Lennox 18D79 Motor
The Lennox 18D79 is a high-performance 1/3 HP blower motor designed specifically for integration within Lennox air handlers and furnace assemblies. Operating on a 208/230V single-phase power supply, this induction motor is engineered to maintain precise CFM output across various static pressure gradients. As an OEM-spec Lennox replacement motor, it features a robust capacitor-run design that ensures long-term reliability in continuous-duty residential and light commercial HVAC applications. When diagnosing weak airflow or bearing failure in the field, this direct drive blower motor offers a seamless mechanical fit, utilizing the standard NEMA frame mounting to align perfectly with existing blower wheels and housings. Its electrical profile is optimized for 1075 RPM operation, providing the stable torque required to overcome system resistance while maximizing heat exchanger efficiency. For contractors, the 18D79 motor kit simplifies a furnace blower motor replacement by eliminating the need for bracket modifications or lead extensions, ensuring the system returns to its factory-rated performance levels immediately.
