California Air Tools 20040C Powerful 4.0 HP Ultra Quiet & Oil-Free 20 Gallon Horizontal Air Compressor – 220V

Product Description

The California Air Tools 20040C is a powerful 4.0 HP ultra-quiet and oil-free stationary air compressor designed for professional workshops, garages, CNC applications, milling equipment, and other demanding pneumatic applications. With a large 20-gallon horizontal steel tank, the compressor provides substantial air storage while maintaining a relatively low operating noise level of 75 dB.

The 20040C uses two powerful 2.0 HP SP-9421-22060 motors operating at only 1,680 RPM. Its oil-free dual-piston pump system is engineered for high performance, durability, and reduced maintenance, with a pump life cycle of 3,000+ hours before wear. The compressor delivers 12.80 CFM at 40 PSI and 10.60 CFM at 90 PSI with a maximum pressure of 125 PSI.
