Looking at a used air compressor its a Devilbiss portable compressor 1.5 HP, 3 gal,125 psi says 5.4CFM.Now I know nothing about these units other they push air lol,the seller says its in excellent condition and was not used not much, and I talk him down to 50 dollars from 70.What I would like to know what can i used it for other than pumping up tires up witch i am kind of interested in,but would like to know if it has any other uses.Thanks again. :???:
