Industrial air compressor. Bought new at Farm and Fleet about 10 years ago. I am downsizing to a smaller portable one as I don't need such a powerful heavy duty one anymore. Has a 60 gal tank, 230 volt 3.7 hp motor, 155psi max pressure. It powered my 3/4 inch impact wrench for semi lug nuts so it does great. I haven't used it much for about 8 years now since I sold my semi tractor. It's still wired up so I can demonstrate. 6one2 5nine 7 three 922
