The CALIFORNIA AIR TOOLS  Ultra Dry, Oil-Free & Ultra Quiet Air Compressors with Air Dryers are designed to be one of the quietest air compressors in the industry removing 98% of the moisture from the air.

The powerful motors operate at only 1680 RPM creating less noise, vibration and creating less wear.

The Oil-Free Dual Piston Pump System is  engineered for longevity, high performance and durability.

To dry the air from the air compressor an Aftercooler and Dryer are utilized.



The aftercooler is a heat exchanger for cooling the discharge air from the air compressor. The water vapor from the compressed air is condensed into liquid form and pushed into the Air Dyer.

The Ultra Dry Air Dyer is specially designed to remove 98% of the water vapor from the air to protect sensitive tools and machinery.

PDP performance range (-20' F. to -51' F.)

Air Quality: ISO 8573 - Class 2.3.1

These Ultra Quiet & Oil-Free Air Compressors with Air Drying Systems are designed for industries such as, Dental, Dental Lab, Medical, Biotech, Laser, 3D Printing and others with a need for Dry Clean Air.

If you plan on using an air tool or machine on a continuous basis, it is a good idea to multiply the “CFM” x 2 to get a continuous CFM rating for the tool or machine.

Most all air tools and machines are rated for intermediate usage (not continuous).

Always consult the air tool or machine manufacturer for the correct CFM requirement.
