A local business has put an industrial air compressor out in their yard for sale. It has a Lincoln 25hp/230v/3phase electric drive motor, a Quincy 2 cylinder compressor, and a 200 gal/200 psi tank. The price is right so, What should I look for and how can I test this thing to make sure it works. Also, what do I need to do at home to make the 3 phase electrical motor work right...Thanks for your help...Tom.
