Devilbiss 44643 7.5HP Compressor Head Pump 24CFM. For sale is this used Devilbiss 44643 7.5HP Compressor Head Pump 24CFM. It is in fair cosmetic condition. It has a decent number of scuffs and scratches from prior use and is fairly oily and dirty. The head is missing one bolt, but the hole is not stripped and will only need the bolt replaced. See photos below for more details on physical condition. I tested the compressor by hand only and it does turn over and I can feel some compression. We tested the compression with a guage while turning it by hand and found that it had about 90 PSI. It may have more at normal running speed, but we cannot guarantee it. Quick Stop Auctions //.
