4.0 HP, 20.0 Gal, Steel Tank, Auto Drain, Ultra Quiet Oil-Free Air Compressor - California Air | CAT-20040CAD

California Air Tools 20040CAD: 4 HP, 20 gallon, auto drain, 75 dB

The 20040CAD is the open frame version of California Air Tools' twin pump 4 HP compressor: two 2 HP oil free pumps on a 20 gallon horizontal tank, 10.6 CFM at 90 PSI, 125 PSI maximum, with the EZ-1 timed automatic tank drain fitted at the factory. At 75 dB it is quiet enough to run in a two bay garage, a cabinet shop or a small body shop without ear protection. Buyers who need the same output but even less noise should look at the 20040SPCAD, which puts this compressor inside a sound proof cabinet.

What 10.6 CFM runs: impact wrenches, die grinders, nailers and staplers of any size, a tire machine, and a mid size HVLP gun or DA sander for normal shop use rather than all day production. It is not a continuous duty machine (treat it as roughly 70 percent on, 30 percent off), so for a sander that runs for hours or a second technician, step up to the 60040CAD with its 60 gallon tank or the 6 HP 20060CAD.

Power: 220 volt single phase, 14 amps, on a NEMA 6-15 plug. Give it a dedicated 20 amp 220 V circuit and plug it straight in; do not run it on an extension cord. The auto drain opens on a timer, so place the unit where the discharge can reach a floor drain or a bucket. It weighs 141 lb and ships by freight.

For spray painting or any air tool that hates water, add the RD-91503 refrigerated dryer downstream and a filter regulator at the hose. See more California Air Tools compressors, other 10 CFM compressors and 125 PSI compressors.
