What this blower is and what it delivers
The FUJI ELECTRIC VFZ601A-7W is a regenerative ring compressor rated for 5 hp on a three-phase supply, drawing 13.2 A at 230V or 6.1 A at 460V AC, 60 Hz. It delivers a maximum flow of 173 cfm and a maximum operating pressure of 133.5 in wc, with a maximum vacuum of 95 in wc. The 2-inch NPT female inlet and outlet are sized for standard industrial piping.
The 133.5 in wc maximum operating pressure and 95 in wc maximum vacuum define the blower's working envelope for pneumatic conveying, aeration, or vacuum lifting. The 173 cfm flow rate at free delivery drops as backpressure or vacuum load increases; the performance curve (not reproduced here) governs the actual operating point. The 13.2/6.1 A current draw at the respective voltages sets the branch-circuit protection and conductor sizing — per the NEC, a 125% continuous-load factor applies if the blower runs for three hours or more.
Construction and environment
The housing is aluminum with a Totally Enclosed Fan-Cooled (TEFC) enclosure, rated NEMA Premium IE3 efficiency. The maximum ambient temperature is 104 °F, with a maximum air temperature rise of 160 °F above ambient — so inlet air at 104 °F yields discharge air up to 264 °F. Thermal protection is pilot-duty type, meaning it switches a control circuit rather than interrupting the motor current directly. Compliance marks include CE, CSA, and UR RoHS.
