Upgrading a California Air Tools 10020C Compressor

Upgrading a California Air Tools 10020C Compressor

The California Air Tools 10020 compressor is marketed as a quiet compressor, but as stuff wears out, the compressor gets loud. To improve it, safety couplers replace the originals and the unloader valve is muffled. Empty to full cycle times reduces to 123s from 330s. Sound levels reduce so that it’s practical to work in a small shop without hearing protection.

Inspiration for the improvements are form Kamtechnik’s examples: 1 and 2. Also, improvements by others to consider.
