The FUJI ELECTRIC VFZ501A-5W is a three-phase Ring Compressor — a regenerative blower rated for 2.7 hp at 575V AC, 60 Hz. It delivers 135 cfm of air against a maximum operating pressure of 84.7 in wc and pulls a maximum vacuum of 83 in wc, making it suited for pneumatic conveying, aeration, and vacuum hold-down applications where a continuous-duty, oil-free air source is needed.
Ratings and construction
The Totally Enclosed Fan-Cooled (TEFC) aluminum housing carries a NEMA Premium IE3 efficiency rating, so it meets the current U.S. energy-efficiency standard for motors in continuous industrial service. Full-load current draws 3.0 A at the rated 575V — a figure that governs conductor sizing and overload relay selection in the panel. Inlet and outlet are both 1-1/2 in NPT female, which matches standard Schedule-40 pipe threads for direct connection to the process piping. Thermal protection is listed as Pilot Duty — meaning the internal thermostat switches a control circuit (typically a contactor coil or PLC input) rather than interrupting the motor current directly; the starter must provide the motor overload protection.
