The AccuSpray HVLP System 23K uses a 3-stage turbine to supply air, not an air compressor. It runs on standard 110V, less than 12 amps power, so you can use it virtually anywhere an extension cord will reach. The turbine contains no oil, so the possibility of oil getting onto your paint job via the air line is eliminated. Also, the air from the turbine is pre-heated and dry, so the possibility of condensation forming in the lines is eliminated. Unlike 2-stage turbines, delivers 85 cfm at 5 p.s.i. at the gun, which is perfect for automotive paints and yields a consistantly smoother finish.
