Best Quiet Air Compressors Reviewed: Perfect for your Workshop or Garage [2021]

Air compressors are a great tool to own since they have more torque and power than electrical tools.

They come in handy for many uses around the home and are a must for any workshop.

But the biggest issue you will face with an air compressor is the sound that it produces.

In a study by the National Center for Biotechnology Information(NCBI), it showed that air compressors producing noise levels over 100 decibels can lead to noise-induced hearing loss, a big problem a lot of loud appliances like air compressors and non-quiet shop vacs can have.

This is why it is important to find the best quiet air compressor on the market so you can reduce the risk of noise-induced hearing loss.

Why Choose a quiet air compressor?

As we’ve mentioned before, the constant use of an air compressor that produces over 100 dB of sounds can lead to Noise-Induced Hearing Loss.

If you are working in a workshop or if you are the owner of a workshop, investing in a quiet air compressor is the best thing to do for yourself and your employees.

You do not have to worry that quiet air compressors will not perform as well as their louder counterparts.

In some cases, they are far better thanks to newer technology being integrated into these smaller and quieter units.

If you already have an exceptionally loud air compressor, then read this tutorial on how to build a generator quiet box that can also quieten a loud compressor.

What to look for in the quietest air compressor

Before you jump on the internet and purchase the first quiet air compressor you see, there are a few things to keep in mind.

Let us take a look at what you need to look for in the quietest air compressor.

Noise Level

The first thing would be the level of noise that the machine produces.

Look for the decibel level that is stated in the manufacturer’s specifications.

The lower the decibel level the better for you and any around you when the air compressor is in use.

Anything below 79 dB should be good enough although you want to aim a little bit low to maybe 60 dB which allows you to have a normal conversation without raising your voice or shouting.

Cubic Feet Per Minute(CFM) and Pressure Per Square Inch(PSI)

CFM tells you how fast your air compressor can supply air when it is in operation.

Low CFM ratings means it won’t work for certain big jobs because it will take forever.

Too high means you may end up causing damage.

This is why it is important to find that balance. 

Remember CFM and Pressure Per Square Inch(PSI) go hand in hand so the higher CFM at a good PSI count, the better the machine is.

The ideal quiet air compressor can be anywhere from 0.6 to 5 CFM at 90 PSI.

Tank Size

Tank size may not matter in some instances, for example when using your quiet air compressor for little jobs at home.

However, for industrial purposes, tank capacity plays an important role and can save precious time.

It’s simple really, the bigger the tank the more it holds and the smaller the tank the less air it holds.

Smaller tanks will have to refill air after a very short period while a larger tank can keep going for a long time without pausing to refill.

If you need a lot of air, a twin-tank air compressor is what you will need.

Portability

You may find instances where you want to move the air compressor or take it with you.

If that is the case then you will have to watch the weight, build, and dimensions of the machine.

Go for a lightweight option and try to choose one that is specifically advertised as being easily portable.

Those are the ones that will be designed to ensure you have no trouble moving the air compressor from place to place.

Some of those units come with large wheels and handles which lends to their portability. 

That being said, if you require lots of air, you will need an air compressor with a large tank so your unit may not be easily transported.

Oil Lubricated or Oil-free

They both have their advantages and disadvantages which makes the decision a bit harder.

Oil-lubricated air compressors lubricate various parts of the device which helps to quieten the sounds and ensure the longevity of your unit.

However, maintaining an oil-lubricated air compressor can be tedious with regular check-ups and cleaning.

Oil-free on the other hand requires very little maintenance but may not be as quiet as an oil-lubricated air compressor.

This all comes down to personal preference so feel free to make your own choice.
