This is a BRAND NEW EconoMaster Universal 3-Speed Furnace Blower Motor. The EconoMaster part # is EM3587 & F48AD25A01. It is 1/2 HP, 115 Volt, and 1075 RPM. It replaces motors with between 2 and 5 speeds (your furnace will only use two speeds- one for heat and one of AC). The frame size is 48 (5 5/8" diameter) and the rotation is reversible. Thanks for looking and good luck!
The motor you are purchasing is brand new. When installing a new motor the motor manufactures highly recommend that you install a new capacitor at the same time. Old capacitors can become weak over time and have a negative effect on the new motor. We have the capacitor that goes with this motor in our store. You can locate it using part # CAP011003O.
