V-Fan Fiberglass Slant Wall Exhaust Fan 36 inch Variable Speed 15250 CFM 230 Volt 936230-1

To order a complete 36" fiberglass fan, select one FAN, one CONE & one SHUTTER. Photo is a representation of complete fan with cone. Second photo is to show VFD. Older-style Triac-controlled variable speed fans would get less efficient the slower they ran due to regulating the voltage, thereby making the CFM/Watt (or (m3/hour)/W) worse. The V-Fan motor is not only VFD-driven, meaning the frequency (hertz) to the motor is driven, but it’s also a PMAC motor, yielding greater efficiency than induction VFD-driven motors. V-Fan is direct drive - so no belts to maintain or bearings to grease The VFD gives you the control you need to provide the ideal environment Features: Features a Permanent-Magnet (PMAC) motor and individually-tuned integral drive. Available in fiberglass (36”, 50”, 54”), Sable™ (36”, 54”), galvanized (36”, 54”) and Z-Fan™ materials (36”, 54”). Fan options include single or three phase inputs in either 50 Hz (please call for 50Hz) or 60 Hz at 200-240V, 380-420V or 420-
