Westinghouse 904502 Blower Motor 1075 Rpm 1/3 Hp 120V

Product Description

The WESTINGHOUSE 904502 is a 3-speed PSC blower motor rated at 1/3 horsepower and 1075 RPM, designed for forced-air HVAC applications. Operating on 120 volts at 60 Hz, this motor delivers counter-clockwise (CCW) shaft rotation and features a 4-inch shaft length suited for direct-drive blower assemblies. It is a common replacement motor for residential air handlers, furnace blowers, and similar forced-air equipment. Licensed HVAC technicians and skilled service pros handle installation as part of routine blower section service or motor replacement calls.

This motor fits residential forced-air systems where a 3-speed, 120-volt direct-drive blower motor is specified. The CCW rotation and 4-inch shaft length make it compatible with a range of direct-drive blower wheel assemblies found in standard residential air handlers and furnace blower sections. Where multi-speed control is required for low, medium, and high fan settings, this motor covers all three positions.

• 1075 RPM rated speed for consistent blower performance
• 1/3 HP output suitable for residential direct-drive blower applications
