The FUJI ELECTRIC VFZ901A-7W is a three-phase regenerative blower — a Ring Compressor — rated for 14.7 hp output, delivering up to 574 cfm of air at a maximum operating pressure of 138.5 in wc or a maximum vacuum of 110 in wc. It is wound for dual-voltage 230/460V AC at 60 Hz, drawing 39.1 A on the low-voltage tap and 18.9 A on the high-voltage tap. This is a Totally Enclosed Fan-Cooled (TEFC) unit with an aluminum housing, carrying a NEMA Premium IE3 efficiency rating. Thermal protection is integrated as Pilot Duty, and the maximum ambient temperature for operation is 104 °F, with an air temperature rise limit of 180 °F. Ports are 3-inch NPT female on both inlet and outlet.
Because it is a TEFC design with NEMA Premium IE3 efficiency, it is suited for continuous-duty applications in environments where dust or moisture is present — the fan-cooled enclosure keeps contaminants out of the motor windings while maintaining thermal performance. The aluminum housing resists corrosion better than cast iron in humid or mildly corrosive atmospheres.
Approvals on file include CE, CSA, UR, and RoHS compliance — covering European, North American, and material-restriction regulatory requirements. No official successor or cross-reference exists because the part remains active; no second-source substitute is listed by the manufacturer.
