The California Air Tools 10020C 2 HP 10 Gallon Ultra Quiet Steel Tank Air Compressor is designed to be one of the quietest 2.0 HP air compressors in the industry having only 70 decibels of sound. The powerful motor operates at only 1,680 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 fuel piston pump system is engineered for high performance and durability. The CAT-10020C Air Compressor has an oil-free dual piston pump designed to have a life cycle before wear of 3,000 plus hours compared to other comparable air compressors with life cycles of 500 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).
