4.0  HP (Rated/Running)

20 Gallon Steel Tank

80% Air Drying System

12.80 CFM @ 40 PSI      

10.60 CFM @ 90 PSI

220 Volts / 60 Hertz / Single Phase

The CALIFORNIA AIR TOOLS 20040DC Ultra Quiet & Oil-Free Air Compressor with Air Drying System is designed to be one of the quietest  4.0 Hp air compressors in the industry having only 75 decibels of sound.   

The Powerful Twin 2.0 HP (SP-9421-22060) motors operate at only 1680 RPM creating less noise and less wear.

The SP Series of Ultra Quiet Air Compressor Motors have been designed to increase duty cycle and allow for longer continuous run times (i.e. may run continuously at 5.3 cfm @90 PSI, or up to 30-40 minutes at a time, at 10.6 cfm @90 PSI).

The Oil-Free Dual Piston Pump System is engineered for high performance and durability.

The CAT-20040DC Air Compressor has a Oil-Free Dual Piston pump designed to have a life cycle before wear of 3000 Plus hours compared to other comparable air compressors with life cycles of 1500 hours or less. 

The Oil-Free pump allows for use in a variety of temperatures  (cold starts) and uneven terrains (no oil in the pump).

The large 20 Gallon Steel Air Tank is just the right size for shop or garage.

The Air Dryer is specially designed to remove the 80% of the water vapor from the air to protect sensitive tools and machinery. 

To dry the air from the air compressor an Aftercooler and Dryer are utilized.

The aftercooler is a heat exchanger for cooling the discharge air from the air compressor. The water vapor from the compressed air is condensed into liquid form and pushed into the Air Dryer.

Designed for the person looking for Power, Dry Air,  Air Flow and     Less Service with at Least 30% Less Noise!
