Replacement Motor, 120V

This replacement blower motor is engineered for Lennox 33W12 HVAC systems, delivering reliable performance in residential and commercial climate control applications. Rated at 1/2 HP with variable speed capability ranging from 0 to 1200 RPM, this electronically commutated motor (ECM) provides flexible operational control to optimize energy efficiency and comfort levels. The motor operates on 120/240 VAC single-phase power at 50/60 Hz frequencies, drawing 7.4 amps at 120V or 4.3 amps at 240V for adaptable installation options. Constructed with a NEMA 48 frame, this motor supports Class B insulation and includes integrated electronic overload protection for enhanced durability and safety. Maximum torque output reaches 42 oz/ft at 1050 RPM, while maintaining a continuous minimum operating speed of 300 RPM. The motor accommodates both clockwise and counterclockwise rotation from the control end, providing installation flexibility. Ideal for heating and cooling systems requiring precise airflow management, this replacement motor ensures consistent operation across varying load conditions. The variable speed design reduces energy consumption compared to fixed-speed alternatives, contributing to lower utility costs and extended equipment lifespan. Electronic speed control allows the motor to adjust automatically based on system demands, improving overall HVAC system performance and indoor air quality. This replacement unit is designed as a direct fit for existing Lennox 33W12 applications, simplifying installation and minimizing system downtime. Suitable for HVAC contractors, facility managers, and building service professionals seeking reliable motor replacement solutions.
