It delivers 31 CFM at 100 PSI on 100% duty cycle with an 80-gallon vertical ASME tank, footprint of 34 x 26 x 70 inches, and 546 lbs shipping weight. The 460V wiring is factory-installed — if your facility runs 460V 3-phase service, this is the correct model to order. Do not run a 230V motor on 460V service. Order the right voltage from the start and avoid motor damage.\u003c\/p\u003e\n\n\u003ch2\u003eWhy 460V 3-Phase?\u003c\/h2\u003e\n\u003cp\u003eMany industrial facilities, body shops with heavy equipment, and manufacturing operations standardize on 460V 3-phase distribution because the higher voltage allows smaller wire gauges over long panel-to-equipment runs and reduces amperage draw on the distribution system. If your panel is more than 50 feet from the compressor location, 460V wiring will require a smaller, less expensive wire run compared to 230V at the same HP. If your facility already runs 460V 3-phase for other equipment, keeping everything on the same voltage simplifies electrical maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eAir End and Drive
