My Search for a Quiet Air Compressor

When I was looking for a new compressor, one of my requirements was to find a quiet air compressor.  Most of us have experienced what it’s like to be exposed to the roar of the normal air compressor and it made my ears ring.

My old compressor was a jewel but I have to say it was loud!  I was totally prepared to pay extra for a compressor that not only fit my needs but hummed instead of imitated a 747 jet.  I knew the neighbors would appreciate it and I’d feel less inhibited about running it for my various projects.

There are a number of factors that affect the noise level of an air compressor.  The size of the compressor is a definite cause of noise.  A small air compressor will have a smaller power unit and this will tend to result in a much quieter operating level.

Most home compressors run on electric power and of course this makes for quiet operation.  In the field of silent or quiet air compressors, the most common type is the piston compressor.  These compressors feature technology that isn’t new by any means but they produce much less noise.

There are air compressors that are designed with the objective of being a very quiet air compressor.  They usually feature technology that insulates, dampens or resists vibration as the compressor runs.  There is no compressor that I’m aware of that is totally silent but by combining some of these technologies they certainly lessen the decibel level of older air compressors.

The Makita MAC700 which I recently bought and highly recommend has an oil-lubricated pump and is equipped with a large automotive style filter for increased air intake and greater efficiency. The Big Bore oil-lubricated pump is also more efficient: the MAC700 runs cooler and at half the RPM’s of most competitive units, resulting in greater motor and pump life and lower noise.

I wanted a quiet air compressor but also one that fit all of my do it yourself and project requirements.  I knew the Makita was a good compressor but the user comments and reviews on Amazon sold me when they talked about how quiet this air compressor is.

Comments like: “I would say this unit is half as loud as those typical oil-free models”,  “I am very pleased to report that the unit is as quiet as advertised”, “Surprisingly quiet for the power it produces” and many others testifying to what a quiet air compressor this is.

I’ve done an extensive review on the Makita MAC700 which sells for under $200 on Amazon so click here to check it out.
