The CAT-4620A series of California Air Tools air compressors offer a 4.6 gallon, horizontal aluminum tank. The entire unit weighs approximately 70-pounds. It is not the most lightweight air compressor on the market, but it is compact and light enough to allow contractors to move the unit from worksite to worksite.


Surprisingly, this little unit is quite powerful, with a max pressure setting at 125 PSI and pushing out a whopping 5.3 CFM at 90 PSI. The twin aluminum air tanks are rust resistant, and the oil-free design allows users to enjoy maximum performance without worrying about when to change the oil, keeping the unit on a level terrain, or a need to replace parts.

Additional Benefits

The ultra-quiet, oil-free design of the CAT-4620A air compressor offers an essential benefit that many building sub-contractor teams and homeowners will enjoy. This air compressor allows users to connect more than one air tool to the unit – enhancing performance and reducing the amount of time necessary to complete simple project tasks.

Who It’s For

Designed to be one of the quietest, most powerful compact air compressors on the market, the 4620A air compressor model is a great selection for residential homeowners, business owners, and building sub-contractors. However, some users have reported that certain parts on the unit are made of poor quality materials or appear somewhat unprofessional in appearance.2


  • Oil-free design
  • 2 quick-release connectorsallows you to connect multiple air tools at once
  • Quiet
  • Allows users to connect the power cord into a normal 15-amp power outlet


  • Low to moderate build quality on certain parts

The quiet functionality and oil-free design coupled with the ability to connect more than one tool to the unit at once definitely makes it worth the purchase, but if you’re want something that offers higher quality construction, you may want to consider a different model, such as the Porter Cable C2002.
