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.*

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. 

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 80% 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 80% Air 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!

                                          EZ-1-2321 Auto Drain Valve Factory Installed

The California Air Tools EZ-1 Automatic Drain Valve has been designed to eliminate manually draining your air compressor air tank.

The manually set timer allows you to set the time for both the frequency and duration of the draining process.

Optional PTFE Black Hose Tubing, 8 mm (10 feet) to connect to Automatic Drain Valve, Air Dryer Valve or Condensate port - Order Here.

Automatic Drain Valve Feature:

Easy Start Valve Feature:

The Easy Start Valve feature allows for a easier start up using less starting amps. The Easy Start Valve releases a small amount of air from the pump at start up to produce a no-load condition  allowing the motor to spin freely. This no-load start up requires less amps for a easier start up in cold temperatures.

NOTE: May not be suitable for applications requiring extremely low pressure dew points (PDP) below 2C or 36F. If ISO compliance is required (i. e. ISO 8573 2.3.1 with PDP performance of -29F to -50F) then a desiccant-based air dryer system will be required. California Air Tools offers 6 Ultra-Dry air compressor models which achieve a PDP average of -40F (-40℃) and outputs 98% ultra dry/clean air with 0.01 um particulate filtering -- CLICK HERE
