If your building does not have three-phase electrical service — and most shops in the U.S. do not — this unit closes the gap between the performance you need and the power you actually have. With 40 CFM delivered at 135 PSI, paired with a 120-gallon horizontal storage tank, it handles continuous production work without the pressure drops that plague piston compressors running the same horse power.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotary Screw Technology:\u003c\/strong\u003e Continuous-duty oil-flooded rotary screw design produces steady, pulsation-free air — unlike piston compressors that cycle on and off and heat the air with each stroke.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Phase Power — No Electrician Rework Required:\u003c\/strong\u003e Runs on 230V single-phase service, the standard residential and light-commercial supply.
