California Air Tools 20040DSPCAD 4.0 HP Ultra Quiet Oil-Free 20 Gallon Air Compressor with 80% Air Dryer, Automatic Drain & Soundproof Cabinet

Product Description

The California Air Tools 20040DSPCAD is a 4.0 HP ultra-quiet, oil-free air compressor designed for professional applications where reduced noise and dry compressed air are important. It combines a 20-gallon steel air tank, an 80% air drying system, a factory-installed automatic drain valve, and a soundproof cabinet into one complete compressed-air system.

Operating at only 65 dB, the 20040DSPCAD is designed for indoor environments such as offices, shops, stores, warehouses, and other workspaces where compressor noise is a concern. The powerful twin 2.0 HP motors operate at 1680 RPM to help reduce noise, vibration, and wear.

The oil-free dual piston pump system is engineered for high performance, durability, and long service life. The integrated 80% air drying system helps remove water vapor from compressed air to protect sensitive tools and machinery, while the EZ-1 automatic drain valve eliminates the need to manually drain accumulated moisture from the air tank.

Applications

The California Air Tools 20040DSPCAD is suitable for automotive painting, dental milling, workshops, shops, stores, warehouses, offices, and other indoor professional environments where quiet operation and reduced moisture in compressed air are important. The 80% drying system is also designed to help protect sensitive pneumatic tools and machinery from water vapor.

Maintenance

The 80% dry air system uses desiccant that should be replaced approximately every 3,000–4,000 motor or pump operating hours, typically every 1–2 years depending on usage. California Air Tools recommends replacing the two 2 HP motor-pump air filters every 2 years, or annually when the compressor is operated in dusty or dirty environments. The automatic drain valve should also be checked periodically to ensure proper operation, while the cabinet exhaust fans and ventilation areas should be kept clean.
