Westinghouse 621891 Blower Motor 3/4 Hp 208V

Product Description

The WESTINGHOUSE 621891 is a replacement blower motor rated at 3/4 HP and 208 volts, designed for use in modular indoor blower assemblies. This motor drives the blower wheel in forced-air ventilation and air handling equipment, maintaining airflow through the system. Licensed HVAC technicians typically source this part when the original motor has failed due to bearing wear, winding failure, or overheating. At 3/4 HP and 208 volts, it is suited for light commercial or residential air handling applications where a direct OEM-style replacement is required.

This motor is intended for installation in modular indoor blower units. It fits the MB5BM model platform and is compatible with BM-1200KB and BM-2000KC blower assemblies. These units are commonly found in commercial or light commercial indoor air handling applications. The motor mounts within the blower housing and connects to the blower wheel to deliver conditioned or ventilated air through the duct system.
