          Quiet air compressor

          best quiet air compressor

          From the outside the California Air Tools CAT-6310 looks like an ordinary single stage air compressor complete with a 6.3 gallon “hot dog” air tank, 2 horsepower motor, easy lift handle and two oversized wheels for convenient transport. Its when you turn her on that the difference is clear, the difference is audible.

          Its quiet, really quiet. When most compressors are decibel ratings in the low to high 80s, the CAT-3610 is at 60 measly decibels, just to give you an idea of how loud that is, a normal conversation is 65 decibels. Since every 10 dB increase is doubles the level of how loud sound is perceived, that means the CAT-6310 is up to 3 times quieter than comparable air compressors.

          How it works

          How does California Air Tools do it? Well, they engineered not one, but two oversized cylinder heads that pump out at nearly half the speed of a normal single cylinder motor that normally would be banging away as fast as it can going nearly twice as fast, and causing excessive, heat, vibration, and lots of NOISE! Our hats are off to California Air Tools for engineering an easy to use and easy to love air compressor.


          Lets talk a little more about the motor, its an oil-less or sometimes called “oil-free” design so you do NOT have to worry about maintaining and changing oil every time the levels drop or when the oil gets too dirty. This unit uses oil inside; however it is a sealed chamber so no maintenance.

          It’s not perfect

          Now the bad news is performance did drop a bit, but not enough to to be concerned about, The performance specs are still good, just not as good a other, louder competitors: 3.8CFM @ 40PSI and 2.35CFM @ 90PSI with a maximum pressure rating of 120PSI. Thats pretty impressive specs when you consider its so quiet that you can literally hold a conversation with it running right next to you.

          We would absolutely recommend the California Air Tools CAT-6310 unless you NEED an air compressor for heavy duty jobs like framing a house or powering a disc grinder and/or paint gun. This is the quietest air compressor on the market. A side by side comparison with a similarly sized compressor and you will understand why the moderately higher price is well worth the lower noise level.

          • Overall Score - 8.9/10
