California Air Tools 20040DSPCAD Powerful 4.0 HP Ultra Quiet & Oil-Free 20 Gallon Air Compressor with 80% Air Drying System & Automatic Drain – Soundproof Cabinet, 220V

Product Description

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

The compressor features twin 2.0 HP motors operating at only 1,680 RPM, delivering 12.80 CFM at 40 PSI and 10.60 CFM at 90 PSI. The soundproof cabinet is lined with acoustic insulation to reduce noise and vibration, resulting in an operating noise level of only 65 dB.

The integrated 80% air drying system uses an aftercooler and activated alumina desiccant to reduce water vapor in the compressed air. The factory-installed EZ-1 automatic drain valve uses an adjustable timer to control the frequency and duration of tank draining, reducing the need for manual moisture removal.

• CNC and machining applications
• General engineering applications
• Medium-duty pneumatic equipment
• Moisture-sensitive tools and machinery
• General compressed-air applications requiring reduced noise

Maintenance

The oil-free dual-piston pump eliminates the need for compressor oil and reduces routine lubrication requirements. The 80% 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 EZ-1 automatic drain valve reduces the need for manual tank draining. Its manually adjustable timer controls both the frequency and duration of the draining process.

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.
