Overview
Powering air tools such as nailers, drills and spray guns is the job of this California Air Tools compressor, which uses an aluminum tank and a corded electric motor. A filter is included.
The reason to look is a quiet, portable compressor with a stated flow rate and a filter in the box. The limit is that bars is surely a mislabel for pressure, so confirm the real maximum with the maker.
Who it's for
Hobbyists and tradespeople who need modest air volume in a workspace where noise matters. Rated air flow limits the choice of tools. Heavy users of sanders or grinders may need a bigger unit.
Pros and cons
- Low noise rating
- Pressure unit looks wrong
- Heavy at the listed weight
- Tank size entries disagree
Performance notes
Air flow in cubic feet per minute decides which tools it can run continuously, while tank size smooths out bursts. A smaller tank refills often under steady use. Low noise comes from the motor and pump design.

Frequently asked questions
What air tools can the California Air Tools compressor run?
The listing recommends airbrushing, drilling, nailing and spraying. Check each tool's air requirement against the 6.4 CFM flow rate.
Is the maximum pressure really 125 bars?
The listing says 125 bars, which is far too high for a portable compressor. Treat it as a unit mistake and confirm the pressure with the maker.
