What is A Vacuum Pump?

When you think of a vacuum pump, it’s common to think of the vacuum cleaner in your closet at home. However, a vacuum pump is a mechanical device used in various air compressor systems, specifically designed to remove air or gas from a sealed area to create a low-pressure or negative-pressure environment, often referred to as a vacuum. These pumps, though seemingly unimportant, have a wide variety of uses and applications across numerous industries.

Measuring the Performance of Vacuum Pumps

The performance of vacuum pumps is typically measured by several key parameters:

  • Ultimate Pressure – This is the lowest pressure that the vacuum pump can achieve, usually measured in torr or millibar, and is a critical measure for applications requiring very low pressures.
  • Pumping Speed – Expressed in volume per unit time (such as cubic feet per minute, CFM), this indicates how quickly a vacuum pump can evacuate air from a space. Higher pumping speeds translate to faster evacuation times, which is vital for high-throughput industrial processes.
  • Throughput – This refers to the amount of gas that can be processed by the pump in a given time, often correlated with the pump’s ability to handle gas loads effectively.
  • Power Consumption – Understanding how much energy a vacuum pump consumes during operation is essential for assessing its efficiency and operating cost.
  • Leakage Rate – The rate at which air or gas leaks back into the vacuumed space. A lower leakage rate indicates a more efficient vacuum seal, which is particularly important in maintaining high vacuum levels over time.
  • Compression Ratio: This measurement indicates the pump’s capability to compress the gas from its entry point to its discharge point and helps determine the efficiency of a vacuum pump in reaching and maintaining desired vacuum levels.

The Science Behind Different Vacuum Pumps

A vacuum pump operates by removing gas or air molecules from a confined space, creating a vacuum within that space. They do this via a mechanical, pneumatic, or hydraulic process, depending on the type of vacuum pump. There are primarily three main types of vacuum pumps: positive displacement pumps, momentum transfer pumps, and entrapment pumps.

Positive Displacement Vacuum Pumps

Positive displacement vacuum pumps are the most common type of vacuum pump and operate by mechanically expanding a cavity, allowing gasses to flow, then sealing off and compressing the cavity to eject the gasses into the atmosphere or another chamber. This type is particularly effective for creating low vacuums and is widely used due to its simplicity. The most common types of positive displacement pumps include:

  • Piston Pumps – Utilize a piston moving back and forth in a cylinder to compress and move the gas.
  • Diaphragm Pumps – Use a flexible diaphragm that moves up and down to create vacuum conditions without contaminating the gas with lubricants.
  • Liquid Ring Vacuum Pumps – Employ a rotating impeller and sealing liquid (typically water) to create a vacuum by forming a liquid ring within the pump.
  • Rotary Vane Vacuum Pumps – Contain a rotor with sliding vanes that press against the housing of the pump, trapping gas and moving it through the pump system.
  • Scroll Pumps – Involve two spiral-shaped scrolls, where one remains stationary and the other orbits to trap and move gas toward the exhaust.

Momentum Transfer Vacuum Pumps

Also known as molecular pumps, these use high-speed jets of dense fluid or rotating blades to propel gas molecules out of the chamber. This type of pump is particularly useful when a higher vacuum level is required.

Entrapment Vacuum Pumps

These pumps capture gasses using chemical reactions or changes in physical conditions to capture and contain gas molecules. They are used for creating ultra-high vacuums and generally do not have moving parts, which minimizes maintenance.

Each type of vacuum pump offers distinct advantages and is suited to particular applications. It is essential to select the right type to ensure efficiency and effectiveness in any given application.

What Does The Governor on an Air Compressor Do

Various red air compressors and equipment in a room.

Table of Contents

What is an Air Compressor Governor and What Does It Do?

An air compressor is made up of several components, one of which is the governor.

The governor regulates the amount of air pressure generated within an air compressor, usually measured in pounds per square inch (psi). It operates based on preset minimum and maximum air pressure levels to prevent overly high pressure that could break the system. When the pressure reaches a specific cut-out pressure, which is the maximum pressure limit set to prevent excessive pressure build-up, the governor signals the compressor to stop pumping air.

Conversely, once the air pressure decreases to below the cut-in pressure threshold, which is the minimum pressure required to ensure the system operates effectively, the governor signals the compressor to start the loading phase and build air pressure again.  So, how does it work?

How a Governor Works

Similar to how the thermostat in your home keeps the temperature within a comfortable range, the governor retains the air pressure within an appropriate range to ensure the system has the appropriate pressure to function correctly. 

Firstly, the governor is connected to the system by an airline. Once the air pressure starts to build in the air system, reaching its maximum, or cut-out pressure, the governor, detecting this higher pressure, prompts the unloader mechanism to open. This specifically designed unloader port now allows the air to bypass, diverting it away from the air compressor and hence ceasing any further inflation.

As the system operates, the air pressure diminishes. The moment this system pressure descends below the minimum, or cut-in pressure, the unloader mechanism in the governor ceases discharging the air. Instantly, the compressor restarts building air, continuing until reaching the cut-out pressure again. During this process, the governor also interacts with the purge valve. When the governor signals the unloader mechanism, it simultaneously activates the purge valve in the air dryer system. This valve opens to release moisture and contaminants collected during the compression phase, ensuring that only dry, clean air is circulated back into the system. This is a continuous cycle that ensures the air system is responsive and maintains optimum pressure for operations. 

Controlling the Speed

The governor plays a pivotal role in controlling the speed of an air compressor by adjusting how quickly the compressor cycles between the cut-in and cut-out pressures. By fine-tuning these settings, operators can manage the frequency and duration of the compressor’s run times, which directly impacts energy consumption and wear on the compressor. Adjusting these parameters allows for better control over the compressor’s speed, leading to more precise management of airflow and pressure, which can be particularly beneficial in applications requiring a consistent delivery of compressed air over a long period.

Can a Governor be Adjusted?

Adjusting a governor involves setting the cut-in and cut-out pressure thresholds to the desired levels. This is typically done by turning a screw on the governor, which changes the tension on a spring inside the device. The tension adjustment affects when the governor activates the unloader mechanism, thus controlling when the compressor stops and starts pumping air.

It’s important to consult the compressor’s manual or a professional technician when making these adjustments to ensure they are done correctly and safely. Incorrect adjustments can lead to system inefficiencies, increased wear and tear, or safety hazards.

Troubleshooting and Maintaining Your Governor

The value of an air compressor relies on its smooth and efficient operation. In case you’re experiencing trouble with your air compressor not building pressure, there might be issues with your governor. Here are some common issues and how to deal with them:

1. Leaks: If your system cannot hold a consistent tank pressure, it is often a result of a leak or multiple leaks. To detect leaks, listen for a hissing or whistling noise and apply a mixture of soapy water around the area, and look for bubbles indicating the presence of an air leak. If bubbles are present, there is a leak that needs to be sealed or replaced.

2. Fluctuation in Air Pressure: A faulty governor could lead to a constant fluctuation in air pressure so keep an eye on your air pressure gauge. If the cut-out or the cut-in psi is inconsistent or fluctuates wildly, your governor could be faulty and may need to be replaced.

3. Sticking Unloader Valve: Sometimes the unloader valve may stick in the ‘loaded’ or ‘unloaded’ position, disrupting the normal cycling of air pressure. Lubricating the valve and checking for dirt or debris can often resolve this issue but if the problem persists, the valve may need to be replaced.

4. Worn Internal Components: Over time, internal components of the governor such as springs or pistons can wear out, so perform periodic inspections and replace worn parts to prevent failure.

5. Inaccurate Pressure Settings: Incorrect calibration of the governor can lead to improper pressure settings, causing the air compressor to either overwork or underperform. Recalibrate the governor periodically, especially after repairs or replacement of parts, to ensure that the governor operates within the designated pressure settings.

6. Improper Installation: If the governor or its connections are not installed correctly, it can lead to various issues including leaks, pressure imbalances, and other operational failures. So, ensure that all connections are secure and that the governor is mounted according to manufacturer specifications to prevent such issues.

What is a Compressed Air Audit?

Have you wondered how much power your air compressor is using? Or if it’s working as efficiently as it could be? These are the types of questions that can be answered with an air compressor audit.

A compressed air system is an intricate setup that includes dryers, filters, pipes, storage tanks, motors, and more, all working together to deliver compressed air where it’s needed. But, like any complex system, it needs regular check-ups to ensure it’s running at peak performance.

This is where a compressed air audit provides a thorough health check for your system. An audit analyzes your setup, checking everything about your compressed air system, from air usage and pressure readings to energy consumption and energy efficiency. In addition to identifying problems, a major piece of a comprehensive audit is finding opportunities to make your air system more efficient, reducing energy costs, and power consumption, and even improving your system’s operational reliability.

What Happens in an Audit

A typical compressed air audit requires one week or less of onsite time and consists of the following procedures:

1. Perform a Comprehensive Site Survey

Before you can conduct a compressed air audit, you need to understand your system and the equipment that comprises it. A site survey performed by a professional with extensive compressed air expertise will yield the most reliable results. This knowledgeable individual can determine if you’ve placed your compressors properly and assess the overall system dynamics.

2. Check for Leaks and Other Issues

As air compressor leaks are a primary culprit of excess energy consumption and associated higher costs, checking for them should be a top priority on any compressed air audit checklist.

3. Examine Air Filters

Air filters perform the crucial role of preventing contaminants from entering the unit. Over time, dirt, oil, and debris can clog the filters, allowing poor-quality air to pass through the system. Consequently, the equipment will need to work harder to deliver pressurized air on demand. An audit should include checking all filters and recommending cleaning or replacements as needed.

4. Detect Artificial Demand

Artificial demand occurs when a compressed air system operates at a higher pressure than necessary, typically to compensate for leaks or flow fluctuations. This extra demand causes the compressor to work harder, resulting in energy waste and increasing the risk of equipment damage. Compressed air audits can determine if artificial demand exists, and recommend the most reliable and cost-effective solution to ensure your compressors function at the lowest possible pressure point without affecting system performance.

5. Assess Air Dryer Compatibility

Dryers perform the critical function of cooling the air and removing moisture. However, to get the full benefit from your air dryer, it must be compatible with your air compressor. Otherwise, you’ll end up wasting money by using a dryer that has to work too hard or perform a task that doesn’t meet its functional requirements. A knowledgeable auditor can determine if you’re using the best equipment for your facility’s unique compressed air system configuration and make recommended upgrades if necessary.

6. Evaluate Storage Capacity

The more compressed air your system can store, the less frequently your compressors will need to operate. The result is more efficient equipment that lasts longer and requires fewer repairs and substantial cost savings for your business. An audit can determine if your compressor’s tanks provide sufficient storage capacity for your applications. If not, there are several options for increasing it. For example, it may be possible to couple two tanks to create a larger reservoir. If the compressor is a reciprocating unit, the air produced by the piston can flow through a connected tube into the tanks.

7. Optimize the Operating Schedule

Many companies fall into the habit of running their air compressors when they don’t need them. Some even leave them on during weekends or other times when the facility is empty. The simple step of shutting down compressors during off-hours can result in substantial energy savings and reduce the burden on your equipment.

8. Implementation

Compressed air audits offer little value if the company doesn’t implement the auditor’s recommendations. It’s important to develop a strategy for making upgrades cost-effectively and you should also schedule a follow-up audit after making the changes to assess their effectiveness.

How to Conduct an Audit

A typical analysis takes one week or less of onsite time and consists of the following procedures:

  1. Asses Supply Equipment
  2. Evaluate Storage Capability
  3. Determine Air Demand
  4. Address Production Issues
  5. Create System Diagrams
  6. Determine Operating Expenses

3. Inspect Air Filters

Air filters are vital for preventing contamination. Over time, they can become clogged, leading to inefficient system operation. The audit process should include a thorough inspection of filters, with recommendations for cleaning or replacement as needed.

4. Detect Artificial Demand

Artificial demand, created when systems operate at higher than necessary pressures, often compensates for leaks or fluctuations, wasting energy and risking equipment. Audits should pinpoint any artificial demand, suggesting solutions to minimize pressure without compromising performance.

5. Evaluate Dryer Compatibility

Ensuring that your air dryer is compatible with your compressor is critical for removing moisture efficiently without overworking the equipment. During the audit, an expert should assess system compatibility and suggest upgrades if needed.

6. Assess Storage Capacity

Adequate storage reduces the need for constant compressor operation, enhancing efficiency and longevity while saving costs. An audit should evaluate if the current storage is adequate and explore options for expansion if necessary.

7. Optimize Operating Schedules

Unnecessary operation of compressors, especially during downtime, can lead to wasted energy. An audit can provide a strategy to shut down equipment when not in use which can yield significant savings.

8. Implement Recommendations

Compressed air audits do very little if the company doesn’t implement the recommendations. It’s important to develop a strategy for making upgrades cost-effectively and you should also schedule a follow-up audit after making the changes to assess their effectiveness.

Understanding the Importance of a Compressed Air Audit

The process of performing an air compressor audit involves using advanced tools to measure system performance, identify any problems, and find opportunities to improve your system efficiency.  Here’s why an audit is an indispensable tool for your operations:

Replacing An Air Compressor Tank

The air compressor tank is the reservoir of pressurized air, and it’s crucial for the function of your air compressor. A sturdy and high-functioning compressor tank safeguards the quality of the air you use and increases efficiency in operation. Even the best-maintained air compressors will need to have their tanks replaced at some point, owing to wear and tear and the constant pressure the tanks are subjected to. 

Steps To Replacing An Air Compressor Tank

To successfully replace your air compressor tank, you will need a variety of tools including a drill with different-sized sockets for removing and attaching bolts, a flathead screwdriver, a Phillips head screwdriver, and a pair of pliers or an adjustable crescent wrench. In addition to using these tools, knowing the components of an air compressor and their placement will make this process much easier and smoother.

1. Power Off:

The first and most important step is to turn off and unplug the air compressor. Remove any power cords that could turn on the air compressor and remember that safety should be your primary concern. Always double-check that the compressor is completely powered down before proceeding with any maintenance tasks.

2. Drain the tank:

Next, release the drain valve located at the tank bottom to get rid of any residual moisture or air. Allowing the tank to fully drain will ensure a safer and simpler disconnection process.

3. Disconnect the old tank:

Once emptied, use the right tools to disconnect the old tank and detach any drain valves, hoses, pipelines, wires, and pressure switches. Be very mindful of the electric motor wires and mark or photograph their positions to aid with reassembly. Take care to inspect the condition of all components for any signs of wear or damage that may need attention during the replacement process.

4. Remove the old tank:

This stage might need some muscle. Compressor tanks, particularly the larger gallon tanks, can be heavy. Be sure to lift properly or use equipment aid like a dolly to avoid injury. Take your time during this step to ensure the old tank is removed safely and without causing damage to surrounding equipment or structures.

5. Install the new tank:

Position the new air tank and carefully reconnect all drain valves, hoses, pipelines, wires, and pressure switches, ensuring that the new tank is oriented correctly. Double-check all connections to ensure they are secure and properly tightened to prevent any leaks or malfunctions once the compressor is back in operation.

6. Test before final use:

Before you begin using your new compressor tank, ensure that everything’s been installed correctly. Turn the power on, allow it to pressurize, and watch for leaks or other issues. If you run into any problems, turn the system off immediately and consult a professional.

When you face compressor tank failure, check the relief valve, automatic drain valve, and pressure switch to see if these components need replacement parts before deciding to install an entirely new compressor tank. However, if you aren’t comfortable tackling this task yourself, we recommend seeking the expertise of a professional to ensure the best results and to guarantee that that installation is performed safely and correctly.

Common Reasons For Replacing An Air Compressor Tank

Air and pinhole leaks are quite common in older compressor tanks that have not been properly maintained. It’s important to look for small pinhole leaks because if left unattended, they can lead to bigger issues like a tank rupture. If you discover any pinholes in your tank, you should replace the tank immediately. Using sealing products may provide a temporary fix, but over time, this could pose a safety risk.

2. Corrosion

Corrosion is a natural enemy of compressor tanks, often resulting from exposure to moisture over time. When corrosion becomes significant, it weakens the tank’s structure, requiring replacement to avoid failure.

3. Damage

Physical damage from accidents or misuse can compromise the safety and functionality of an air compressor tank. Even minor dents or deformities can affect performance, making replacement the safer and more efficient choice.

4. Capacity Needs

Upgrading to a larger compressor tank might be necessary as your air demand grows. A tank that’s too small for your needs can lead to frequent cycling of the compressor, reducing efficiency and increasing wear.

5. Age

Over time, even well-maintained tanks will succumb to wear and tear. An aging tank may not yet show visible signs of failure but replacing it proactively can avoid unexpected downtime and potential hazards.

6. Performance

It’s important to be observant of changes in the air compressor’s performance. An increase in the time it takes your compressor to pressurize, a noticeable decrease in power and air pressure, continuous cycling, or distributed air that is too moist or oily are clear signs and causes for concern and replacement. 

Remember, the cost of neglecting signs of a failing air compressor tank can be enormous, causing higher energy consumption, compressor failure, or even a tank explosion. So, while a new tank may be an upfront investment, the longer-term savings in energy efficiency, minimization of downtime, and secured safety make it an essential one.

How to Increase CFM on an Air Compressor

Looking to boost the CFM of your compressed air system? Unfortunately, it’s important to note that you cannot exceed the CFM rating of your compressor, but if your air compressor is not reaching the intended CFM that it is rated for or you are aiming for better performance, there are a few simple things to optimize your system’s efficiency like choosing a larger compressor, using larger tanks, add a second compressor and choosing a suppressor with a higher pressure. But first, what is CFM?

What is CFM?

CFM, which stands for Cubic Feet per Minute, is the amount of airflow you’ll get under the specific conditions of your location. It measures how much air your compressor can draw in per minute, taking into account factors like temperature and pressure. So, if your compressor has a rating of 100 CFM, it means it can generate 100 cubic feet of compressed air every minute. This measurement plays a significant role in telling you how efficiently an air compressor functions, essentially dictating the amount of air that a compressor can supply.

However, when we talk about CFM in the context of an air compressor, it’s not a stand-alone measurement, and we’re referring to the volume of air that the compressor can produce at a given PSI (pounds per square inch). For example, your air compressor would be rated for 100 CFM at 100 PSI, not just a certain CFM. It’s essentially the power output of your compressor, or in simpler terms, the breath of your air compressor. A higher CFM essentially means that your air compressor is capable of supplying more air and is often more powerful.

The interaction between pressure and CFM varies based on the type of compressor you’re using.

For a Variable Speed Drive (VSD) compressor, CFM and pressure (PSI) have an inverse relationship. If you increase the pressure, the CFM decreases, and vice versa: lowering the pressure increases the CFM.

In contrast, Fixed-Speed compressors produce a constant airflow regardless of use. Altering the CFM is not possible without adding more horsepower (HP) Reducing CFM isn’t an option either because using less air means the compressor will be in an unloaded state more often than not. However, changing the pressure affects the energy required to maintain that pressure. A higher pressure means more energy consumption as the compressor works harder to maintain air production and vice versa.

Increasing CFM on an Air Compressor

When it comes to finding means of increasing the CFM on an air compressor, several factors come into play.

Selecting The Right Compressor

Choosing the right compressor based on your CFM requirement is fundamental to meeting your air needs. Always check the CFM requirement of the tools you intend to use and make sure your air compressor meets or exceeds that requirement for best performance.

Opting for A Bigger Compressor

This option might sound obvious, but a bigger compressor can indeed deliver a higher CFM than a small compressor. This is due to their larger pump and motor sizes, which allow them to compress more air per revolution, thereby providing a higher CFM. However, ensure that the larger compressor has the same duty cycle, or you may only be able to run the compressor at half load.

Choosing A Compressor with Higher Pressure

Air compressors with a high maximum PSI allow the compressor to fill the tank with more airflow, thus enabling higher CFM. However, remember that the output pressure will not exceed the maximum pressure switch setting. 

Use of A Larger Tank or Add an Extra Tank

A larger tank size or extra tank will store more air, allowing your compressor to rest between fill cycles – hence extending the duty cycle. This will keep you from having to try to increase the CFM of your whole system to meet your peak demand. This can vastly increase the efficiency of your system as you can draw on this air supply and get by with a lower overall CFM.

Adding A Second Compressor

Adding a second compressor can actually increase your total CFM. This can be useful during busy times when you need more air, as it splits the workload between the two compressors. 

Before deciding on any course of action, evaluate the cost-effectiveness and long-term sustainability of your decisions. Remember, when increasing the CFM on your air compressor, it’s critical to understand your CFM needs, compressor capabilities, and the options available to you.

Practical Tips to Maintain Maximum CFM

Establishing optimum CFM on your air compressor is only one part of increasing CFM. The other equally important factor is maintaining and creating an environment where your compressor can perform at its best. Here are some practical tips to maintain maximum CFM for your air compressor.

Maintain Your Compressor

Regular maintenance goes a long way in ensuring your air compressor’s performance and longevity. Keep your compressor clean and check for and repair any air leaks as they can significantly decrease your compressor’s CFM.

Correct Usage of Pneumatic Tools

Try not to use more than one high CFM tool at a time if you can help it. Overloading your air system can reduce the CFM and put a strain on your compressor.

Preventing Pressure Drop

Pressure drop in any air system is an enemy of efficiency and can affect the delivered CFM adversely. Keep your pipe runs as short as possible and ensure the size of the pipes is correctly matched to the CFM and PSI output.

Maintaining Output Pressure

Make sure that your air pressure at the tool end is sufficient. The air pressure drops as the hose or pipe gets longer, so do take the required measures to compensate for the pressure drop.

Managing the Duty Cycle

Make sure not to exceed the air compressor’s duty cycle, which is the amount of time a compressor provides consistent pressure (PSI) and flow (CFM). Operating the compressor continuously, exceeding its duty cycle, can result in overheating and a consequential drop in CFM.

Air Compressor Modifications to Get More CFM

Want more CFM from your current air compressor without reducing your facility’s PSI? It’s doable, but it involves substantial changes. Simply tweaking settings won’t push the CFM beyond what your compressor is designed to handle. To achieve a higher CFM, you need to enhance both the compressor pump and motor, essentially requiring you to add more horsepower into the system. This kind of upgrade, especially for large industrial compressors, is essentially rebuilding the compressor for a higher CFM capability, which can be costly. 

In many instances, it’s better to invest in a new, bigger compressor (like a Variable Speed Drive or VSD model) or to supplement your system with an additional compressor. If your current setup doesn’t suffice your specific needs in terms of CFM capabilities, selling it and using the proceeds towards a more capable unit might be a smart move.

Reasons Why Your Air Compressor is Not Building Pressure & How to Fix It

Old air compressor that is not building pressure.

Jump To:

TL;DR: Air compressors are essential pieces of equipment in various industries. They provide the much-needed power for tools in manufacturing plants, automotive garages, construction sites, and more. But what happens when your air compressor is not building pressure as it should? Understanding this problem is crucial, as it can drastically impact the function and efficiency of your tools and operations.

Understanding the Basics of Industrial Air Compressors

Before we get to the root of the problem, it’s important to understand how an air compressor works. As the term suggests, an air compressor compresses air into a tank, thereby building pressure. This compressed air can then be used to power various tools and machinery. Here are some of the key components of your air compressor that are important to understand…

     

      1. Compressor Tank: A storage unit for compressed air, allowing the compressor to cycle less frequently and providing a reserve of air for tools.

      1. Pressure Switch: A switch that automatically starts or stops the compressor when the air pressure in the tank reaches a preset level.

      1. Unloader Valve: Releases trapped air from the compressor head and discharge line when the compressor stops, easing the motor’s startup.

      1. Check Valve: Prevents compressed air from flowing back into the compressor pump from the tank, ensuring one-way flow.

      1. Safety Valve: A safety device that automatically releases air if the pressure in the tank exceeds safe levels to prevent explosions.

      1. Pressure Regulator: Adjusts the air pressure coming from the tank to a consistent, lower pressure level for tools.

      1. Bleed Valve: Allows manual release of air from the tank to reduce pressure or drain moisture.

      1. Tank Valve: A valve typically at the bottom of the tank used for draining condensation or the tank itself.

      1. Tank Pressure Gauge: Gauge displays the current air pressure inside the compressor tank.

      1. Relief Valve: Similar to the safety valve, it’s designed to release excess pressure from the tank or system to avoid over-pressurization.

    So What Might Be Causing Issues With Insufficient Pressure?

    Signs of a compressor not building pressure could include:

       

        1. Compressor runs continuously without stopping

        1. Low pressure on the gauge

        1. High-pressure fluctuations

        1. Excess oil carryover 

        1. Noticeable air leaks

      While these are some general issues, the actual problem may differ based on specific use cases and the specific model of the air compressor. It’s always recommended to get a professional to examine the problem, ensuring the correct diagnosis and a safe solution.

      Why Your Air Compressor Is Not Building Pressure: How to Diagnose and Fix the Problem

      Now that we know the components at play and the possible issues, how do you go about diagnosing the problem?

      You need to be observant and careful as you proceed with these checks and fixes – always prioritize safety while handling machinery. While professional assistance is recommended, you can perform these simple checks to gain a better understanding of the problem.

      5 common reasons air compressor is not building pressure.

      Listen Carefully for Leaks & Seal Them

      Problem: The first step is to check for any air leaking out of the compressor tank. Start the compressor and listen for resulting sounds. An air leak will be accompanied by a characteristic hissing or whistling noise. Use your hand around the air line and connection points to see if you feel any air escaping. You can also use a bit of soapy water applied on the suspected leak points. If bubbles appear, you’ve got a leak.

      Solution: If air leaks are identified in the air line or connection points, they can be sealed using a variety of methods depending on the size and location of the leak. This could involve tightening a connection or applying a sealant. Be sure to take the compressor out of service and depressurize it before attempting any repair.

      Pressure Switch & Unloader Valve Testing and How to Fix

      Problem: The pressure switch is typically found close to the compressor motor and is connected to the air line. To test the pressure switch, watch the compressor when it cycles. If it’s not cycling off when it reaches cut-out pressure, there is likely an issue with the pressure switch. On the other hand, if the compressor isn’t reliably starting up again when the tank pressure drops, the issue can be with the unloader valve.

      Solution: If you’ve identified a problem with the pressure switch, correcting the cut-in and cut-out pressure as per the manufacturer’s recommendations can help restore the correct compressor cycling. If the issue is with the unloader valve, this part likely needs to be replaced.

      Issues with the Reed Valve & Check Valve and How to Fix Them

      Problem: You might need to dismantle a portion of your compressor to get to the reed valves. If the reeds are damaged, broken, or not seated correctly, they can negatively affect the compressor’s ability to build air pressure. The next step is to inspect the check valve which is located on the outlet of the air compressor. A functioning check valve is crucial to maintain air pressure in the air tank. If air escapes back into the pump via a faulty check valve, you will have a hard time building air pressure.

      Solution: Depending on the issue and the specific valve – unloader valve, check valve, reed valves – the valve may need to be cleaned, adjusted, or replaced. Before attempting any such repairs, make sure to consult with the manufacturer’s guide or contact a professional from Advanced Air & Vacuum to avoid any risks.

      Other Components of the Air Compressor to Monitor

      Checking the Power Supply: If your compressor motor is struggling to maintain or reach the required PSI, it could be due to a lack of proper power. Ensure that the power supply is not interrupted or restricted in any way. You might want to consult a qualified electrician for this check.

      Cleaning the Air Line: Debris or build-up within the air line can restrict the airflow and affect the pressure. Cleaning or replacing the air line can help improve the pressure. This should be done with care and proper tools to avoid any risk of damaging the air line.

      While these checks may seem simple, remember that they require careful execution and might involve manipulating parts of your compressor machinery that you are unfamiliar with. The safest and most effective way to deal with air compressor pressure problems is always to call the professionals.

      The Importance of Regular Maintenance in Preventing Air Compressor Issues

      We’ve walked through the ins and outs of why an air compressor might fail to build pressure and how to diagnose and fix this issue. But what if we could prevent these hassles from happening in the first place? That’s where routine maintenance comes in.

      Reasons Why Your Air Compressor is Not Turning On & How to Fix It 

      An old air compressor that won't turn on.

      Jump To:

      There is incredible value in understanding the basics of how our everyday equipment works, especially for complex machines like air compressors. The more you know about your machine, the better you’re able to troubleshoot when something goes wrong. But what do you do when your air compressor is not turning on?

      At face value, this problem may seem straightforward – if the machine doesn’t turn on, then it’s broken. However, the truth is that several factors can contribute to an air compressor refusing to start. The issue could be due to a faulty pressure switch, electrical disturbance, or even a lack of regular maintenance. 

      Having a malfunctioning air compressor can be a significant inconvenience, interrupting your activities or even bringing your entire operation to a halt. That’s why it’s worth taking a deeper look into why your air compressor might not be turning on and how to fix these issues.

      5 Common Reasons Why Your Air Compressor Is Not Turning On 

      Knowing the reasons behind your air compressor not turning on is the first step toward addressing this issue. Here are some of the most common causes of an air compressor refusing to crank up. 

      Faulty Pressure Switch

      The Issue: The key role of the pressure switch in an air compressor is essentially to tell the system to start and stop. When your compressor doesn’t kick on, one common culprit might be a faulty pressure switch. For instance, if the pressure switch is stuck in the open position, it may not send the necessary signal to the compressor, preventing it from working as expected.

      The Solution: If the pressure switch is at fault, in many cases, the best solution is to replace it. Always make sure to replace the faulty pressure switch with one that matches the specifications of your compressor. Consult your owner’s manual or the manufacturer’s website to find the correct part.

      Electrical Issues

      The Issue: Electrical problems are one of the most common causes of air compressor failures. From a blown fuse to issues in the engine compartment, several electrical components could prevent your compressor from turning on. Always ensure that your compressor has power. If it doesn’t, the problem might lie within the power supply, wiring, or a fused connection needing replacement.

      The Solution: If you suspect an electrical issue, the first step is to click the reset switch. If you find a blown fuse, replacing it may bring your air compressor back to life. However, remember that a repeated blown fuse indicates a bigger electrical problem. Consider consulting with an experienced professional who can rectify any underlying issues that are causing this experience.

      Lack of Regular Maintenance 

      The Issue: Regular maintenance is crucial for keeping your air compressor in top condition. Not having routine maintenance leaves your compressor susceptible to various issues, including motor failure or low pressure. Regular checks and servicing can prevent unexpected breakdowns, prolong the life of your compressor, and maintain its efficiency.

      The Solution: The simplest yet crucial action is performing regular maintenance on your compressor. From changing filters and oil to checking hoses and belts for wear and tear, a little care goes a long way to prevent unforeseen issues. 

      Defective Electric Motor

      The Issue: If you notice a humming sound or excessive noise when trying to start your air compressor, it might be an indication of a failing electric motor. Additionally, an overheated or burnt motor due to excessive usage or lack of maintenance can also stop your air compressor from turning on.

      The Solution: A defective air compressor motor usually needs to be rewound or replaced, which should be done by a professional. A regular check-up of the motor and immediate action at the first sign of trouble can prevent extensive damage and costly repairs.

      Low Pressure

      The Issue: The air compressor requires a specific pressure level to kick-start its operations. If you notice that your compressor assembly is not reaching the correct pressure level, the low-pressure switch may be the source of the problem. In this case, you might need to adjust or replace the pressure switch. Alternatively, there could be a mechanical failure involving a check valve, which can cause the compressor to trip under excessive load. In certain rotary screw compressor cases, there may be an anti-start switch that activates if too much pressure is sensed. 

      The Solution: Manually reset the low-pressure switch to tackle low-pressure problems. If resetting doesn’t work, replacing the switch is the best course of action. Remember to replace it with a switch that matches your air compressor’s specifications.

      Understanding and solving these issues will not only ensure the smooth running of your compressor, but will also extend its life, efficiency, and productivity. 


      When to Repair Your Air Compressor & When to Replace It

      Sometimes, despite our best efforts and intentions, an air compressor might just refuse to work, leaving us with the critical decision of whether to repair or replace it. It can be a tough call to make. Here are some guidelines to assist you in making an informed decision.

      Consider the Lifespan 

      A well-cared-for compressor can serve you well for about 10-15 years, given it operates under normal conditions and is regularly maintained. However, if your device is nearing the end of this period and frequently causing you trouble, it might be time to consider replacing it.

      Severity of the Issue 

      If the problem is minor, such as a blown fuse, electrical wiring problems, or insufficient air pressure, it is certainly reasonable to fix it. These fixes are relatively inexpensive and do not take a lot of time. You can do these repairs yourself after a quick search online for your particular model’s wiring diagram.

      However, some problems can be more severe, like a broken air suspension or a faulty compressor motor. When these occur, repairing the compressor might pose a significant challenge and can become an expensive affair. For instance, if the compressor motor is to be replaced, it could cost almost as much as a brand-new unit. In such cases, it might be more cost-effective to replace your machine entirely.

      Downtime 

      If your business or operations depend heavily on the compressor and you can’t afford the time it takes for a lengthy repair, replacing the air compressor might be the most effective route to take.

      Energy Efficiency 

      Older models tend to be less energy-efficient and can lead to high electricity bills over time. Newer models, on the other hand, run more efficiently and provide long-term cost savings. 

      Consider all these factors while making your decision. Still, remember that it’s equally important to consult with experts when you are unsure of the best approach to take. 

      Recognizing the Need for Regular Maintenance

      The ability to troubleshoot and address your air compressor issues when they arise can save you time, money, and frustration. This blog has shed light on the common reasons your air compressor might refuse to turn on and provided practical solutions for each of these issues.

      However, one key takeaway is the importance of regular maintenance.

      Air compressors are expensive tools, which is why it is so important to maintain them to ensure their longevity and performance. One simple yet crucial aspect of maintaining your air compressor is regularly draining it. Whether you are dealing with a large industrial air compressor or a smaller compressor, overlooking the importance of draining can lead to a range of problems, from reduced efficiency to significant damage over time. In this blog, we aim to equip you with an easy-to-follow guide on the process of draining your air compressor, making it a task that you can confidently undertake regularly.

      An air compressor is a vital tool in various industrial, commercial, and even home settings. It powers everything from pneumatic tools to complex machinery. However, like any piece of equipment, it requires regular care to function at its best. Draining the compressor is not just a recommendation; it’s a necessity. This process helps in removing accumulated moisture, which if left unchecked, can cause corrosion and deterioration of both the compressor and the tools it powers.

      So, whether you’re a seasoned professional or new to the world of compressed air systems, this comprehensive guide is designed to provide you with all the information you need to maintain your air compressor effectively.

      Why is it Important to Drain Water from your Air Compressor?

      The functioning of an air compressor is linked to the concept of air pressure and the use of compressed air. In simple terms, an air compressor takes in atmospheric air and compresses it, resulting in a high-pressure output. This compressed air is a powerful resource, but it comes with an often overlooked byproduct – moisture.

      The Basics of Moisture Buildup

      When air is compressed, the moisture that was once dispersed in the atmosphere gets concentrated. This is because air can hold less water vapor when it’s under pressure compared to when it’s at atmospheric pressure. As a result, this moisture naturally condenses and accumulates within the compressor system.

      The Inevitable Moisture Buildup

      As the compressor operates, it continually pulls in new air and with it, more moisture. This is not a sign of a malfunctioning compressor but a natural consequence of air compression. The critical factor here is not the presence of moisture but the management of it.

      Why Draining is Crucial

      Neglecting to drain this accumulated moisture can lead to a host of problems. The most immediate is the reduced efficiency of the compressor. When water mixes with the oil in the system, it affects lubrication, leading to increased wear and tear. But the impact goes beyond just the compressor itself.

      Corrosion: The Silent Culprit

      Over time, moisture will start to corrode the internal components of the compressor, such as the valves and tanks. This corrosion shortens the lifespan of the compressor and can also lead to costly repairs.

      The Far-Reaching Impact of Moisture

      The effects of moisture don’t stop at the compressor. When it makes its way into the compressed air supply, it can damage the tools and machinery that rely on this air. This is particularly problematic in applications where dry air is critical, such as in woodworking or sandblasting. The presence of water can lead to poor finishes, clogged tools, and even failure of pneumatic controls.

      Draining your air compressor isn’t just about maintaining the compressor; it’s about protecting the entire system and the applications it supports. It’s a simple yet vital routine that preserves the efficiency, reliability, and longevity of your compressed air system.

      How to Drain Moisture from an Air Compressor

      Having understood the critical importance of draining your air compressor to prevent moisture build-up and its detrimental effects, let’s jump into the practical steps of this task. Remember, regular draining is key to maintaining the health and efficiency of your air compressor and the entire compressed air system.

      Understanding Your Air System Components

      Before we start, it’s crucial to have a basic understanding of your air system components. The main parts involved in the draining process include the drain valve, aftercooler, receiver tank, and distribution system. Each plays a vital role in the operation and maintenance of your air compressor.

      Step-by-Step Guide to Draining an Air Compressor

      1. Turn Off the Compressor: Ensure that your air compressor is turned off. This prevents any additional pressure build-up while you are performing the maintenance.
      2. Release Pressure: Safely release any residual pressure from the air tank. This can be done by opening the pressure release valve.
      3. Locating and Releasing the Drain Valve: The drain valve is typically located at the bottom of the air compressor tank. In some systems, you might also find a drain valve on the after-cooler. Depending on your compressor model, you might have a manual drain valve, which requires you to open it manually, or an automatic drain valve that does the job automatically at set intervals. Open the drain valve by pulling the ring and allow all the water and moisture to flow out. If your system has an automatic drain valve, check it periodically to ensure it’s functioning correctly.
      4. Close the Drain Valve: Once all the moisture is drained, securely close the drain valve.
      5. Draining Frequency: For manual drain valves, it’s recommended to drain your air compressor after each use or at least daily, depending on the humidity levels and usage frequency.

      Draining Other Air System Components

      Besides the air compressor itself, other components in your compressed air system need regular draining, such as air dryers, receiver tanks, and the piping system. These components can also accumulate moisture and should be included in your regular maintenance routine.

      How to Drain These Other Components

      • Air Dryers and Receiver Tanks: Similar to the air compressor, locate the drain valves and release any accumulated moisture.
      • Piping System: Check for any low points where moisture might collect and ensure they are drained properly. Many piping systems will have a drain valve underneath the drip leg which is placed at the optimal low point.

      By following these steps, you can effectively manage moisture in your air compressor and the entire compressed air system, ensuring optimal performance and longevity. Regular maintenance, like draining, is a small investment of time and effort that pays off significantly in the long run.
