California Air Tools 20040DCAD Powerful 4.0 HP Ultra Quiet & Oil-Free 20 Gallon Air Compressor with 80% Air Drying System and Automatic Drain Valve – 220V

Product Description

The California Air Tools 20040DCAD is a powerful 4.0 HP ultra-quiet and oil-free air compressor designed for applications requiring reliable airflow, reduced noise, and drier compressed air. It combines a 20-gallon horizontal steel air tank with an integrated 80% air drying system and factory-installed automatic drain valve.

The compressor is powered by twin 2.0 HP SP-9421-22060 motors operating at only 1,680 RPM, delivering 12.80 CFM at 40 PSI and 10.60 CFM at 90 PSI while producing only 75 dB of noise. The oil-free dual-piston pump is engineered for high performance and durability with a rated life cycle of 3,000+ hours before wear.

The integrated air drying system uses an aftercooler and activated alumina desiccant to remove approximately 80% of water vapor from compressed air, helping protect sensitive tools and machinery. The factory-installed EZ-1 automatic drain valve uses an adjustable timer to control the frequency and duration of tank draining.

Applications

The California Air Tools 20040DCAD is suitable for applications requiring higher airflow and reduced moisture in compressed air, including:

• Dental offices and dental laboratories
• Dental milling equipment
• Dental air tools
• CNC equipment
• Milling equipment
• Machine shops
• Workshops and garages
• Medium-duty pneumatic equipment
• HVLP painting applications
• General compressed-air applications requiring dry air
• Tools and machinery sensitive to moisture

Maintenance

The oil-free dual-piston pump eliminates the need for compressor oil and reduces routine lubrication requirements. The integrated air drying system uses activated alumina desiccant, which should be replaced approximately every 3,000–4,000 motor/pump running hours, typically every 1–2 years depending on usage.

The automatic drain valve helps eliminate manual tank draining by releasing accumulated moisture according to its adjustable timer settings.

The two air filters attached to the motor-pump should be replaced every two years under normal conditions or annually when the compressor is exposed to dirty or dusty environments. Replacement air filter part number is 90260.
