A quiet air compressor is a pneumatic device that uses either an electric motor, gasoline or diesel engine to transform power into potential energy that’s stored in the form of compressed air/ pressurized air.

A compressor forces air into a tank hence increasing the pressure. Upon the air stored in the storage tank reaches the engineered upper limit, the air compressor automatically shuts off. The compressed air in the storage tank is held until when needed for use. After the air in the storage tank is used up or reaches the engineered lower limits, the air compressor turns on again to repressurize the tank.

According to a study published on the National Center for Biotechnology Information (NCBI) website, the use of regular air compressors (over 100 decibels) is one of the leading causes of Noise-Induced Hearing Loss.

If you frequently use air compressors and want to avoid the risk of NIHL, it’s highly recommended you invest a quiet air compressor and implement other measures that will keep noise levels down.

The best quiet air compressor is California Air Tools CAT-1P1060S Light & Quiet Portable Air Compressor with 56 decibels noise ratings.

What to Consider When Buying a Quiet Air Compressor

There are factors to consider when investing in the best quiet air compressor. It’s essential to take these factors into consideration to get a compressor that meets your specific requirements.

Noise Levels

It’s obvious you want a quiet air compressor- for this reason, the decibel levels play an important role.

As earlier mentioned, something below 79 decibels is considered quiet to avoid the risk of induced hearing loss and noise pollution to your next-door neighbors, a quiet compressor is a must.

The quietest air compressor in this guide is California Air Tools CAT-1P1060S Light & Quiet Portable Air Compressor rated 56 decibels. However, other options are considered quiet, with all below 79 decibels.

PSI CFM ratings and HP

Cubic Feet per Minute (CFM) ratings are important when buying an air compressor. They tell the amount of air the unit will supply during a cycle.

Compressors with higher CFM ratings will provide more air, making them best for larger applications.

Your best would be something with a range of 0.6 to 5 CFM at 90PSI. If you’ll be using the unit as a supplementary compressor for a larger one, consider a range between 0.6-2cfm.

A compressor with 3CFM is excellent for powering light tools and other DIY projects, while 4-5CFM is perfect for a busy workshop.

Another important factor is pounds per square inch (PSI), which measures the amount of pressure per square inch of space. It’s the amount of force your compressor can deliver.

Horsepower (HP) is the amount of power a motor can perform. This factor is not as crucial as CFM and PSI because newer models work just fine even with less HP. Less HP will help save energy bills.

Tank Capacity

The bigger the tank capacity, the more air it will hold. Large tanks are great, especially if you will be undertaking major projects and can handle two or more tools simultaneously.

However, for simple DIY projects, you’ll do fine with a medium-sized tank.

Oil-Free or Oil Lubricated

Oil-free air compressors require little to no maintenance. They are mostly preferred over oil-lubricated counterparts.

Lubricated ones require regular maintenance checks and you to continually check that oil doesn’t drip into the air tank.

For example, Makita MAC2400 Big Bore is the only air compressor in this guide that requires oil lubrication.

Types of Quiet Air Compressors?

Air compressors are essential tools in a rental or construction business. These devices power a wide range of tools from air sprayers, pneumatic wrenches, paint sprayers, and nailers.

It’s important to note that not every air compressor is ideal for every use. Because different air compressors compress air at different atmospheric pressures, it’s important to know which one fits a specific job.

Below is my guide on the different types of air compressors you can get on the market today.

Reciprocating Air Compressors

Reciprocating air compressors are popular in smaller job sites such as home construction or garage projects. They fall under displacement class air compressors.

They are not designed for continuous use and have more moving parts than rotary screw compressors. The moving parts are lubricated with oil, allowing efficiency and smoother operation.

Reciprocating air compressors use a piston located inside a cylinder that compresses and displaces air, resulting in pressure buildup.

There are two reciprocating air compressors: single and multi-stage air compressors.

Multi-stage provides more power and are ideal for intense construction sites such as auto maintenance or assembly.

Rotary Screw Air Compressors

Rotary screw compressors are fall under the positive displacement class. They are ideal for manufacturing industries.

An industrial rotary screw compressor offers a 100% duty cycle and can operate for 24 hours nonstop. Constant flow is ensured through a pair of screws that rotate in opposite directions to operate the air sealed in the chamber.

They are durable and ideal for heavy-duty use, such as powering sand-blasting machines or jackhammers.

Axial Air Compressors

These are found in high-speed engines found in planes or ships. They are highly efficient but quite expensive than other types of compressors. Since they give thousands of horsepower, it’s the reason they are reserved for aerospace research.

Centrifugal Compressors

They are known to slow and cool the incoming air in a diffuser to build potential energy. The multi-phase compression process results in a high amount of energy in a tiny machine.

They don’t require much maintenance compared to reciprocating and rotary screw compressors, with some producing oil-free air. They are found in demanding construction sites, such as steel manufacturing plants or chemical plants.

Quiet Industrial Air Compressor

Quiet industrial air compressors are powerful and highly efficient air compressors made from powerful horsepower motors. They can deliver higher CFM at high PSI, and these heavy-duty workhorses are designed to operate at higher pressure levels than their commercial counterparts.

Eaton 5HP Quiet Air Compressor

The Eaton is a heavy-duty quiet industrial air compressor with an 80-gallon tank. The unit is designed for up to 50,000 hours with proper maintenance. It features a low RPM pump that delivers 19CFM @ 100PSI, allowing utmost flexibility to meet your air compression needs.

According to the manufacturer, this unit uses a noise-suppression technology developed by Polar Air Engineers. This results in a noise reduction of 25% compared to standard air compressors.

This technology reduces noise and saves you money which you’d otherwise use to build a structure to isolate the air compressor from the work environment.

The built-in intercoolers allow the air to be cooled between stages, while the aftercoolers allow for a second cooling stage which further cools the air before it’s stored in the tank.

EMAX Quiet Industrial Air Compressor

Like the EATON above, the EMAX quiet air compressor uses a silent air technology that lowers the noise output by 25%.

This is a vertical 2-stage 80-gallon air compressor with a 209-230 voltage rating that delivers max performance for longer periods. The unit utilizes a 1750RPM motor that runs quieter and cooler and increases the pump life.

You get a 5-year warranty upon purchase.

Final Thoughts

Compressors play an integral part in our day-to-day life. And while most of these devices might look resembling each other, they are not as they seem. They are also designed differently and for specific tasks.

For example, airbrushing compressors aren’t designed for high functionality, such as powering pneumatic tools. Consequently, you won’t need a commercial compressor for airbrushing projects.

Where you intend to use your compressor will also affect the type of compressor you’re limited to.

In my case, I have a tiny garage, and my wife got a baby to take care of upstairs. I only got to go for a vertical air compressor rather than a horizontal one. But even when you have a tiny garage like me, you could go for a horizontal air compressor, especially if you’ve cabinets where you can hide the unit.

If you require an industrial size compressor, choosing one that’s already “soundproofed” will go a long way in saving you money in soundproofing costs.

If you’re ever caught at crossroads between oiled and oil-free, remember that oil-lubricated compressors are durable and quieter than oil-free. But you will spend more time and money on maintenance.
