The CALIFORNIA AIR TOOLS 10020SPCAD Ultra Quiet and Oil-Free Air Compressor in Sound Proof Cabinet is designed to be one of the quietest 2.0 Hp air compressors in the industry having only 58 decibels of sound. The Powerful 2.0 HP (SP-9421) motor operates 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-10020SPCAD 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 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. 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. The large 10 Gallon Steel air tank and Soundproof Cabinet is 190 lbs. The sound proof cabinet has two latching doors that allows for easy access to the air compressor and componets. The two cabinet exhaust fans are used to remove air from the cabinet to reduce heat and provide a cooler working condition for the air compressor. The 4 caster wheels makes moving the air compressor from location to location very easy. Designed for the person looking for Power, Air Flow, Less Service and Maintenance with at Least 30 percent Less Noise.
