What is an Oil Free Air Compressor?

An oil free air compressor is a machine that compresses air without oil. Unlike oil-lubricated compressors, which require regular oil changes and maintenance, these compressors are more convenient and energy efficient.

Oil free air compressors are ideal for applications where contamination from oil is unacceptable, such as in the medical, food and beverage, or electronics industries. Due to their efficiency, reliability, and versatility, oil-free compressors are the future.

How an Oil Free Air Compressor Works

An oil free air compressor uses non-oil materials for lubrication and cooling. Instead of traditional oil, materials like Teflon or synthetic oil get used.
The cooling is achieved through water or air-based techniques, which help reduce the compressed clean air temperature. This process leads to more efficient and reliable compression.

Oil Free Air Compressor Pros & Cons

Oil Free Compressor Pros

1. Highly Reliable

The high reliability of oil-free air compressors comes from the fact that they are not oil-based. Unlike oil-based compressors that require regular oil changes, these can work for a long time without any maintenance costs or repairs.

2. No Oil Mist or Drain Discharge

Unlike conventional-style compressors that create oil mist as a by-product, oil free compressors have no discharge of oil at all. This element reduces the risk of contamination, maintaining quality and precision throughout the process.

3. Less Stressed Pistons

Due to the use of synthetic materials instead of oil-cooling techniques, the pistons are less stressed. This results in a much longer effective life span and better durability.

4. Excellent Stability

An oil free air compressor has excellent stability, providing consistent output and pressure without additional adjustments. They maintain a stable air supply, even in demanding applications, making them ideal for high-performance tasks.

5. Energy Efficient

An oil-free compressor has fewer parts that require lubrication, reducing the power required to drive the compressor. This efficiency translates to lower operating costs and reduced energy consumption.

Oil free Compressor Cons

1. Higher Initial Cost

Oil free compressors tend to be more expensive than oil-based compressors. However, their lower maintenance costs and longer lifespan usually offset the cost.

2. Limited Applications

An oilless air compressor is unsuitable for applications requiring high pressures or continuous operation. They are best suited for intermittent use in the medical, food, or electronics industries.

3. Noise Level

Much like their oil-based counterparts, they are overall quite noisy. The noise level can vary with the technology used but is typically higher than other compressors in the same category.

Oil Free Air Compressors vs Oil Lubricated Compressors

Similarities:

1. Refrigeration Cycle

Both air compressors have a refrigeration cycle, which compresses the refrigerant gas to increase its pressure and temperature.

2. Cooling System

Oil-free and oil-based compressors require a cooling system to maintain a suitable operating temperature. Cooling is achieved through either water or air-based techniques.

3. Industry and Application

Both compressors have wide-ranging industrial and application uses, including automotive, manufacturing, and construction industries.

4. Rotary Screw

The rotary screw is a technology used in oil-free and oil-based compressors, providing a highly efficient and reliable compression method.

5. Compressed Air System

Both compressors are used in compressed air systems, where the air is compressed and stored for later use.

6. Control Systems

Both oil-free and oil-based compressors use control systems to regulate their operation. These systems include sensors and microprocessors, which control the compressor’s performance based on data from components within the machine.

Differences

1. Class 0 Certification

Oil-free compressors are often certified as Class 0, meaning they produce no oil, making them suitable for applications requiring oil-free compressed air.

2. Pressure Drops

An oil free air compressor is more prone to pressure drops due to its reliance on water or air cooling techniques, while oil-based compressors can operate at higher pressures due to the use of oil-based lubricants.

3. Environmental Impact

Oil-free compressors are more environmentally friendly since they do not produce oil mist or discharge oil into the environment. This feature makes them ideal for applications where the air grade is crucial.

What Are Oil Free Air Compressors Used for?

Spray Painting

Oil free air compressors are widely used in spray painting applications. These compressors provide clean and dry air, ensuring a high quality finish with no oil mist or water droplets.

Food & Beverage

Oil-free compressors are essential for maintaining food quality and safety. They are used for packaging, processing, and preservation, providing clean, dry air that meets industry standards.

Brewing Beer

Breweries require an oil free air compressor for various applications, like brewing, bottling, and packaging. These compressors provide clean and dry air essential for maintaining the quality and taste of beer.

Textiles

Textile manufacturing companies utilize oil-free compressors to ensure that all aspects of their production, such as washing and drying, produce clean and dry air.

Oil Free Air Compressor Maintenance

These compressors require less maintenance than oiled models but still need routine safety checks and upkeep. Regularly check and clean your safety valves and filters. Also, visually inspect the whole unit, including hoses and seals. Look for cracks and make sure all fittings are secure. If you see anything wrong with your compressor, bring it to Air Power Equipment Co. in OKC for same-day maintenance.

Do you Need to Break in Oilless Air Compressors?

No, you do not need to break in an oilless air compressor. Unlike oil-lubricated compressors, which require a break-in period to allow the oil to circulate throughout the system, an oil free air compressor does not. As a result, they do not require any special break-in procedures.

Oil Free Compressor Life Expectancy

Oil free compressors can last up to 50,000 hours, depending on the type of unit and how well it is maintained.

How to Extend the Life of the Compressor?

1. Follow the Manufacturer’s Maintenance Guidelines

The manufacturer’s maintenance guidelines should get followed religiously to ensure the longevity of the compressor. It includes filter replacements and general maintenance.

2. Regular Cleaning

Cleaning your air compressor can help prevent the buildup of debris and dirt, which can cause damage to the compressor and lead to a decrease in its lifespan.

3. Proper Storage

Proper storage protects the compressor from environmental factors like dust, moisture, and extreme temperatures. Ensure the compressor is stored in a clean, dry, and cool environment.

4. Monitor Air Quality

Monitoring the air quality is essential to ensure that the compressor is not operating in an environment that can cause damage to it. This process includes monitoring for water, oil, and other contaminants in the air supply.

5. Regular Inspections

Regular inspections of the compressor can help detect issues early on and prevent more significant damage from occurring. This inspection includes checking for leaks, unusual noises, and unusual vibrations.

Want to know how to measure your air compressor CFM, PSI, and HP? Well, you’re in the right place! We’ll cover the average HP, PSI, & CFM requirements for industrial, commercial, and personal compressors. So let’s clear the air around compressor power.

Air compressors bring in the surrounding air and create compressed air through their internal components, turning it into a serviceable force for your air tools (pneumatic tools). Let’s start with some basics.

What Is CFM Air Compressor

Air compressor CFM translates to cubic feet per minute; in other words, it measures the volume of air in cubic feet for every minute it moves. So, for example, if your air compressor is rated for 50 CFM, it can push 50 cubic feet of air per minute. 

What Is Air Compressor PSI

PSI is an acronym for pounds per square inch. Thus measuring the amount of pressure placed in a square inch, or in other words, the amount of force that your air compressor can produce. 

What Is Air Compressor HP

Horsepower is the amount of work your air compressor’s motor can deliver. But this holds less importance than PSI or CFM. It just means more or less energy is needed to get the job done. 

What Is The Difference Between HP And CFM

Air compressor CFM is the amount of air possible within an air compressor. For example, a room that is 5000 cubic feet would need a 5,000 CFM system to replace all the air each minute. 

HP or horsepower measures how much energy your air compressor can output. Horsepower refers to 550 foot pounds of compressor power per second (745.7 watts).

Between PSI & CFM

The difference between PSI & CFM is in when what’s being measured. For example, PSI is the measurement of pressure. In contrast, air compressor CFM is the measurement of volume. 

However, both are essential when it comes to air compressors. These two measurement forms correctly identify the requirements for any particular tool or task.

How To Convert HP to CFM

Are you trying to convert HP to CFM? Look no further; converting HP to CFM is as simple as multiplying the airflow by 1.6 and multiplying that result by 0.9. The average horsepower for air compressors ranges between 1.5 and 6.5 HP. 

HP to CFM Conversions

I know what you’re thinking, “gross, math,” but don’t worry. Below you can find the math done for you:

1.5 horsepower – Metric to cubic feet/minute = 1.04 CFM

2 horsepower – Metric to cubic feet/minute = 1.39 CFM

3 horsepower – Metric to cubic feet/minute = 2.08 CFM

4 horsepower – Metric to cubic feet/minute = 2.78 CFM

5 horsepower – Metric to cubic feet/minute = 3.47 CFM

6 horsepower – Metric to cubic feet/minute = 4.16 CFM

6.5 horsepower – Metric to cubic feet/minute = 4.51 CFM

Using this, you can determine what air compressor power you need to get the job done.

How Much HP Does My Air Compressor Need?

So we already discussed that the average air compressor power ranges from 1.5 to 6.5 HP. But it doesn’t just end there. A stationary air compressor that is larger can provide up to 15 HP. Ideal for larger applications. Additionally, ensure you factor in your compressor power source because a lesser compressor power source may not provide the energy needed to reach full HP.

How To Adjust PSI On Air Compressor

Changing the pressure level inside the compressor’s air tank is as easy as turning the regulator knob in a clockwise direction. The machine will start to make more noise, and the readings on the pressure monitor will increase, letting you know that the pressure is indeed intensifying.

How To Increase Air Compressor CFM

You can increase the airflow, or air compressor CFM, on your compressor in a few different ways. These methods include:

• Modifying your outlet size 
• Using an auxiliary storage tank
• Improving your cooling system
• Hooking up two air compressors 
• Lessening pressure

All of which will increase your compressor power adequately. 

How CFM Is Calculated In Air Compressor

Figuring out how to measure your compressor air flow rate may seem daunting, but the math is manageable. 

The formula is CFM = tank volume in cubic feet x standard pressure (ATM) during a cycle x cranks per minute.

CFM/PSI/HP For Industrial Air Compressor

Industrial air compressors are available in various styles and sizes to suit different purposes. The average air compressor CFM output is 185, but some models have higher ratings. For example, high-pressure models can reach 2000-6000 PSI. The average HP for an industrial/commercial air compressor is 5HP. 

An excellent compressor for job sites would be wheelbarrow compressors. These models are perfect for challenging terrain and are designed for work sites. However, these air compressors can weigh as much as 300 lbs, so make sure your job site is wheel friendly. 

CFM/PSI/HP For Commercial Air Compressors

You’ll want a twin-stack compressor for contractors and commercial business owners. A twin-stack system allows you to store more air, so your compressor doesn’t have to run as often. Keep in mind that these air compressors can weigh close to 100 pounds. An excellent air compressor CFM for these is around 6.2, with a PSI of 90 and 2.5HP.

CFM/PSI/HP For Personal Air Compressor

For personal use, a portable compressor’s CFM can rest anywhere from 3 to 11.3 CFM, with a PSI of 90, which is perfect for airbrush painting, a widespread use for personal compressors. Horsepower isn’t something you’ll need to worry about for personal compressors. 

CFM FAQs

Is Higher CFM Better?

The bigger the project, the better it is to have a higher compressor CFM. The higher the air compressor CFM, the more air you can disperse. 

Smaller projects would that wouldn’t need much CFM would be:

• Cleaning electronics
• Quick cleanups after a messy DIY project
• Quick drying after painting

Larger projects that would require more CFM would be:

• Angle grinding, a tool used to cut through metal
• Chiseling, a tool used to cut through metal
• Using a cut-off tool often used in auto maintenance

Can You Lower The CFM Of An Air Compressor?

Reducing the pressure in your air compressor’s tank can quickly reduce the compressor CFM. The compressor doesn’t have to work as hard at lower pressures to push air into the tank.

Does Adding An Extra Air Tank Give Compressor Extra CFM?

Yes, but there is a process to combining air tanks safely. You’ll need the right tools, and you’ll need to proceed with caution, as this can be a risky solution. A safer solution would be switching to a twin-tank system.

What Affects The CFM Of An Air Compressor?

Several factors can affect a compressor’s CFM, including its size and type, the pressure at which it operates, and the airflow rate through the compressor. In addition, the compressor’s motor size and horsepower can affect the air compressor CFM, as a larger motor can deliver more air.

Additionally, the type of compressor, such as a single-stage or two-stage compressor, can also affect the CFM. Finally, the condition of the compressor, such as the components’ wear and tear, can also impact the CFM. 

Finally, an air filter, regulator, and lubricator can positively impact your CFM if installed correctly and maintained properly.

Do business owners need to winterize their offices just as homeowners do? Depending on the circumstance, your office may be closed for the winter months. Or your business has a sprinkler system, or you’re a property manager closing down a pool. Either way, our blog can help. 

So, what tools should you add to your collection? First, a portable air compressor is a great tool all year round, especially during winter. But why should your business buy one? Keep reading to learn how to use an air compressor in winter!

How To Use An Air Compressor In Winter

Ensure you properly test your unit; once you’re confident everything is in working condition before you clear out any water lines. 

If your sprinkler system uses black polyurethane piping, you’ll want to use a psi of 50. If your system is made up of rigid PVC, then a psi of 80 is needed. You’ll want to test your psi output before you clear the lines. 

You’ll want to attach your hose now. First, ensure your hose is long enough to get the job done and clear of any cracks or kinks. Then make sure your drip tray is drained. Clean your compressor filter. Make sure you lubricate any internal parts that have yet to be recently maintained. Finally, check the compressor belts; if you’ve been maintaining optimized conditions, you can get to work. 

How To Use An Air Compressor To Blow Out Your Sprinkler System

Using an air compressor for sprinklers sounds worse than it is, but with our step-by-step guide, you’ll be done winterizing your sprinkler system before you know it. First, you’ll want to shut off the water supply to your system before clearing out water lines. By doing this, you can more easily clear out your irrigation system. 

Next, you’ll open your hose bibs and drain lines of any remaining water. Opening the bib will release pressure and create natural air drainage. You’ll want to give your sprinkler system a few minutes to do this properly. 

Before you start clearing lines, shut off the backflow valves & then open the valve on the air compressor. 

Now attach your compressor hose to the bib on your sprinkler systems mainline. You’ll need to purchase an adapter if the hose isn’t attached correctly. 

It’s important to remember to blow out the furthest sprinkler first and work your way down. For example, some areas are higher in elevation than others. Then you would start with the highest and work down to lower levels.

Once all levels have been cleared, give your sprinkler systems a few minutes to release any compressed air left behind after disconnecting your compressor. Congrats your sprinkler system is now ready for the freezing temperatures of winter!

How To Use An Air Compressor To Blow Out Your Pool Lines

To clear out your pool lines, you’ll want to first prep your pool by:

• Draining your pool below 4″ to 12″ leaving a small amount of water.
• Remove water from skimmers.
• Remove drain plugs from your pool filter, pool pump, and heater.

Unlike your sprinkler system, this project is much shorter. You’ll start by connecting your air compressor to the suction side of your pool’s pump. Then turn on your compressor. Clearing your skimmers and main drain completely may take a few minutes. You’ll know you’re done when you see a light mist released. 

Now you’ll remove any water from your filter. Again, depending on your filter, you may not need a compressor. Instead, there may be a setting on your filter to do this. Again, check your instruction manual to see what is required.

Now connect your air compressor hose to the pressure side; this will push water out of the pool jets/cleaner lines. Then plug the cleaner line and jets with pool plugs, and you’re done! 

How To Use An Air Compressor To Winterize Your RV

Before we put your air compressor to work, you’ll want to: 

• Disconnect your water supply.
• Turn off your water pump.
• Turn off the power to your rig. 
• To be safe, you can turn off your propane.
• Drain the water tank, water heater, and all holding tanks. 

Now it’s time to winterize your RV with your air compressor:

• Connect the blowout plug to the city water inlet.
• Now connect your compressor hose to the blowout plug.
• Set the air compressor PSI to no more than 30.
• Now run your compressor and check each faucet one at a time. Finally, open each faucet to let out water until only air remains. 

To be extra careful, you should make your rounds by adding a small amount of RV antifreeze to your p-traps. Then, add a couple of inches of antifreeze to your toilet bowl.

How To Use An Air Compressor To Winterize Your Office Pipes, Tub, and Faucets

First things first, you’ll want to shut off your main water valve. Then, drain hot/cold water from your home into your outdoors. Then you can flush your toilets & open all faucets. 

Connect your air compressor, set it to 70 psi, and open your sink faucets again to let water blow out. Then open the shut-off valve beneath each toilet to allow air to release, and then close your valve. Then cover up any outdoor drains.

For an extra measure, add a little antifreeze to your toilet and bathtub trap. Then follow up by applying heat trace tape to any piping you are concerned may freeze. While you’re at it, adding weather stripping to your property wouldn’t hurt to fight the cold temperatures.

No Snow? How To Use An Air Compressor To Make A DIY Snow Machine!

No snow? No worries! Your air compressor in winter can also be used as a DIY snowmaker. We’ve found a link to help you build a snowmaker using your air compressor. Making a snowmaker is perfect for your business to grab attention if you’re open during winter. It creates community engagement and will make your business remembered fondly by all.

How To Use An Air Compressor To Clean Your Filters

Need to clean a dirty air filter? Your air compressor can handle this job as well. Inspect the filter to ensure there isn’t any damage, and blast away the dirt. 

How To Remove Snow With An Air Compressor

Are you dealing with a snowmageddon? Are you tired of having to shovel away snow? Why use a shovel when you can use a portable air compressor? Simply blast away the snow, and enjoy the rest of your day. Your employees will thank you.

Air compressor filters are one of the most essential parts of an air compressor. A filter prevents dust and debris from entering, allowing for smooth operation. But not all filters are the same.

Different air compressors may need different air compressor filters. And those particular filters require different maintenance.

Here at Air Power Equipment Co., we’ll break down some important questions about filters for air compressors, as well as take a look at the different types of air compressor filters out there.

As always, feel free to give us a call or visit the rest of our website if you have any questions.

Do I Need a Filter On My Air Compressor?

Yes, you need an air filter on all air compressors.

Providing clean air to your air compressor is essential in so many ways. It extends the lifespan of the compressor, the tools you use with it, and ensures your compressor operates at maximum efficiency.

When Should Air Compressor Filters be Changed?

While every compressor and filter is different, it is common practice to change your compressor filter every 2000 hours of use at a minimum.

Now, 2000 hours is a general rule. But a good eye test can often tell you if a filter needs replacing. If it looks dirty, it is and probably should be replaced. You can dust it off to give it more use, but understand you’ll need to make a trip to the compressor store soon.

If dirty filters become a recurring issue, consider where you use your compressor. Is it in an area that gets more dust and debris than usual? Consider moving to a place with clean air.

Air Compressor Types

The four most common types of air compressors are:

Rotary Screw Compressors

These compressors have an internal cooling system, making them easier to maintain. A rotary screw compressor is a large, industrial-sized compressor that can run with or without oil lubrication.

Two internal rotors turn in opposite directions to generate energy in this compressor. Air gets trapped between the two and builds pressure. These compressors can run for a long time because of the internal cooling system and are great for industrial jobs where constant air is needed.

Reciprocating Compressors

Reciprocating compressors are useful for smaller jobs and home projects. However, reciprocating compressors aren’t designed for prolonged use and need oil to lubricate the internal parts.

This compressor uses a piston and a cylinder to compress air. Reciprocating compressors come in single-stage and multi-stage variations, with single-stage being the less powerful of the two.

Axial Compressors

Axial compressors are massive and typically used in aerospace applications.

Centrifugal Compressors

Centrifugal compressors use multi-stage compression to build pressure efficiently and in a relatively small machine. As a result, they require less maintenance and sometimes don’t need oil lubrication.

Centrifugal compressors can reach roughly 1,000 horsepower and are fit for construction sites.

What is The Best Air Compressor Filter for Painting?

A filter on your air compressor is essential for painting. Otherwise, humidity and moisture in the air can pass through your compressor and dilute your paint with water. The section below will highlight different types of air compressor filters that could be compatible for painting with your air compressor.

Different Uses for Air Compressor Filters

Keeping Out Water

Filters can do a lot to help keep moisture out of your compressor’s tank.

Keeping Out Particles

Particles like dust, dirt, and even insects can enter your air compressor without a proper filter. As you can imagine, these particles can cause quite a bit of damage to your air compressor and potentially clog it.

Different Types of Air Compressor Filters. How do I Choose an Air Compressor Filter?

Coalescing Filters

A coalescing filter removes water and aerosols, including oil up to 0.01 microns in size. Brands like Arrow and Watts make this kind of filter.

What is The Best Use of a Coalescing Filter?

The best use of coalescing filters is in air compressors used for paint spraying, paper manufacturing, and food preparation.

How to Change a Coalescing Filter

To start, clean debris and dust around the manifold block to prevent contamination.

Take the filter out by unscrewing it with a wrench. Once it’s out, check the exposed area for contamination and clean it as necessary.

Have your new filter on hand. Coat the cleaned area with filter oil, spin the new filter, and turn it tight. But be careful not to make it too tight!

When Should I Change a Coalescing Filter?

A coalescing filter needs changing roughly once a year if properly installed and fitted.

How to Clean a Coalescing Filter

If your coalescing filter looks like it needs cleaning, it is best just to replace it to ensure maximum results.

Vapor Removal Filters

Vapor filters remove vapors, chemicals, and sometimes oil from the air through an absorption process with activated carbon.

What is The Best Use of a Vapor Removal Filter?

The best use of a vapor removal filter is in coordination with a coalescing filter.

Because of a vapor removal filter’s design, absorbing water will cause the filter to use itself up very quickly. Therefore, a coalescing filter must come before the vapor filter.

How to Change a Vapor Removal Filter

Always consider your filter’s user manual for changing instructions. If those aren’t available and you need to replace them, turn off the compressor and let it cool completely.

Remove the filter top cover from the filter base. Then, remove the filter. Secure the new filter in its place, and attach the filter top cover.

When Should I Change a Vapor Removal Filter?

A vapor removal filter needs changing roughly every 2,000 hours of use.

How to Clean a Vapor Removal Filter

You can clean a vapor removal filter by removing it and blowing air directly through it to clear out debris. However, replacing it with a new one is the best practice.

Dry Particulate Filters

Dry particulate filters, like the FS Curtis High-Temperature After-Filters, remove desiccant particles after an absorption dryer. You can also apply dry particulate filters at the point of use to help filter particles out of the compressed air. A dry particulate filter works similarly to a coalescing filter.

A coalescing filter takes out water, and a dry particulate filter takes out dry particles.

What is The Best Use of a Dry Particulate Filter?

The best use of a dry particulate filter is to be the last step in your air filtration process. It is helpful to ensure that the air coming out of your compressor is pure and clean. In addition, painting projects may require a dry particulate filter.

When Should I Change a Dry Particulate Filter?

The best practice is to change a dry particulate filter when you change your other filters.

How to Clean a Dry Particulate Filter

There are a couple of ways you can clean a dry particulate filter.

You can clean it by hand gently between the filter ridges and clear out the debris. You can also take compressed air to force out the debris.

If your air compressor is not building pressure, don’t panic! Below, we will talk about the different reasons why this could be happening. 

Air compressors are fantastic tools. You can use them in construction, manufacturing, agriculture, and home use. They can fill tires, power supply to an air tool, and much more.

A key component of air compressors is building pressure to force out air. Sometimes, air compressor pumps struggle to build pressure or can’t build pressure at all.

An air compressor not building pressure is a problem that makes the air compressor useless. Therefore, it would be best if you fixed an air compressor not building pressure as fast as possible to resume your work.

Here at Air Power Equipment Co, we’ve identified some reasons why an air compressor runs but doesn’t build pressure and how to fix an air compressor not building pressure safely.

Broken Intake Valve

With a broken compressor intake valve, your air compressor will still draw air in, but most of it will blow back out from where it came. Your tank will reach a fraction of its capacity when this happens.

How to Fix a Broken Intake Valve

Take out the air intake port filter and feel if any air is blowing back out. If it is, then your intake valve plates are likely broken. 

Your best bet is to visit the compressor repair shop for a remedy. But, first, the compressor must be pieced apart to identify the issue.

Failure in the Pressure Pump Valve 

When the pressure pump valve fails, air will enter the tank on the compression stroke, immediately flowing out of the compressor as it tries to fill with more air. Air flows where there is the least resistance.

Cheaper air compressors have cheaper valves more prone to failure after usage. You can tell your compressor is having pump valve issues when it caps out at a specific pressure lower than it should, despite how long you run it.

How to Fix a Pressure Pump

Like a broken intake valve, the best solution may be to take it into a compressor repair shop. But, first, you must remove the compressor to identify the issue and diagnose a solution correctly.

Broken Compressor Gasket

Gaskets separate the flow of pressurized air and intake air. They break down over time. A broken gasket leads to your compressor not reaching max pressure. 

How to Fix It a Broken Compressor Gasket

The issues caused by a broken compressor gasket are similar to those caused by broken intake valves and failing pressure compressor pump valves. 

Therefore, you may be experiencing a combination of these failures when experiencing air compressor issues. If you have to take apart your compressor to locate the source of the problem, it’s worth replacing all of these parts at the same time if possible.

Failure of the Compressor Piston Seal

A piston seal contains a filter that prevents dust parcels from entering the air compressor. It also has rings that are seals that stop oil from the oil fill tube from dripping into the compressor. 

Old rings can leak air pressure, preventing your compressor from reaching max pressure. 

How to Fix Compressor Piston Seal

Regular maintenance is the best way to prevent this from happening. However, if it goes too long without fixing, metal can grind against metal, and oil can leak into your compressor tank. 

Swap out old rings with new ones at a compressor repair shop, and you’ll be ready to go. Since this repair doesn’t require a complete disassembling of the compressor (that is, if the oil hasn’t leaked into the tank or if the metal hasn’t come in contact with other metal), you should be able to do this repair yourself if you have enough experience. 

However, Air Power Equipment Co recommends visiting a compressor repair shop to get the best results.

Broken Check Valve

A check valve stops compressed air from flowing back into the pump. If your tank reaches high pressure with a broken check valve, it might automatically shut off. 

The valve pressure switch should cut out pressure when max pressure is reached while running. However, it should not be releasing air if max pressure is not reached.

How to Fix a Broken Check Valve

If air leaks out of the unloader valve when the compressor is turned off, you have a faulty check valve. With an hour of labor and an ordered part, you can repair this type of issue by yourself if you have experience.

Ways to Regularly Maintain your Compressor to Prevent these Issues

1. Check Your Filters

   Keep your filters clean. Inspect for debris and dust buildup. Replace filters as recommended or as you see necessary.

2. Do A Pump Test

   This will show you how long your compressor takes to reach maximum pressure. First, empty your tank and measure how long it takes to reach the needed PSI. Different compressors have different maximum pressures, so refer to your owner’s manual to know what yours is.

3. Examine Belts

   Some compressors have a belt drive, much like a car. An old belt could be the reason why you have low pressure. However, an old or damaged belt could also make noise, adding to the already loud sounds produced by an air compressor.

In conclusion

As we laid out, there are many ways that your air compressor can break or fail, leading to low air pressure. 

The good thing is many of these issues are related or happen concurrently. This means a single visit to a repair shop can solve the problem and reduce the likelihood of it happening again in the immediate future.

And you can solve some issues at home with the right tools and expertise.
