J&D Manufacturing J&D Panel Fan, 50" PM 380/460V, 3 Bl Poly, 2.2kW 3Phase Motor, 1/Variable Speed

J&D Manufacturing’s Permanent Magnet Direct Drive 50″ Panel Fan is a game changer. Using only basic 0-10 volt control relays, this fan can efficiently operate at nearly any speed. This allows uniform air recirculation even when on beginning stages. Enabling all fans to run at low speeds eliminates dead or turbulent spots that are often created with full on/off fan stages. The high performance of the Permanent Magnet Direct Drive Panel Fan, means fewer fans are required and the incredible efficiency of 33.5 CFM/Watt when run at lower speeds can save you up to 75% energy savings over traditional fans.
