Our old air compressor looked super sleek and modern, but what good is design if operation is subpar? So I was left with no choice but to continue my search for an air compressor that will not disrupt anyone when in use. My search for ‘quiet air compressor’ led me to the California Air Tools CAT-6310, and it proves to be one of the best choices I’ve ever made.


Ultra Quiet Air Compressor with only 60 Decibels

The most common complain with air compressors is the brutal noise it creates during operation. The California Air Tools CAT-6310 Steel Tank Air Compressor is built with a powerful 1.0 HP motor, operating at only 1680 RPM. It is the only model in the market that boasts having only 60 decibels of sound, which is as quiet as a normal conversation. If noise is a major consideration for you, you won’t go wrong with this unit.

Durable Motor with low RPM

The powerful motor operates at 1 rated HP and up to 2 peak HP with speed of 1680 RPM, which is responsible for the low noise and virtually no vibration. The low RPM feature also improves the life of your air compressor’s motor. Powered by a standard 110V power supply, the motor has a built-in thermal overload protector that turns off the motor when it reaches 135° C or higher during operation.

Very happy with the 8010spc.”

Most customers, though, had the same positive experience as me. Other customers said, “my favorite compressor,” and “Very quiet. This is the only oiless compressor I have ever been able to talk over.” And finally, “Gets the job done and it does not lie. It is very quiet.
