Overview
The California CAT-4620AC pairs a corded electric motor with a 4.6 gallon tank, built as a stationary shop compressor rather than a jobsite unit you carry around.
At 68 pounds and running on a standard 110 volt AC circuit, this compressor is meant to sit in one spot in a garage or workshop. No pressure or CFM figures are listed in the available specs, so match it against your air tools' actual air draw before buying.
- Corded electric, 110V AC power
- 4.6 gallon air tank
- 68 pound unit weight
- 20.7" L x 18" W x 21" H footprint
Who it's for
Suits a home garage or small shop that wants a plug-in compressor for air tools like nailers, impact wrenches or inflators, and has a fixed spot to keep it. Not built for anyone who needs to move a compressor between job sites.
Pros and cons
- Runs on a standard 110V household outlet
- 4.6 gallon tank buffers air demand between cycles
- Compact footprint at 20.7 x 18 x 21 inches
- At 68 pounds it is not a unit you move often
- No listed PSI or CFM rating to match against tools
Performance notes
The 4.6 gallon tank gives the compressor a buffer of stored air between motor cycles, which matters more for tools that draw air in short bursts than for ones that run continuously. Running on a standard 110V AC circuit means it plugs into a normal household outlet without special wiring.
