OEM Lennox Blower Wheel — 47K28

The genuine OEM Lennox 47K28 blower wheel is the squirrel-cage fan responsible for circulating air through your Lennox furnace or air handler and out into the ductwork. Factory-balanced and matched to your unit's motor, it delivers the precise airflow (CFM) your system was designed around — a key factor in efficient heating, effective cooling, and consistent comfort in every room.

Telltale symptoms of a bad blower wheel include diminished airflow at the registers, noticeable vibration, a rhythmic thumping or rattling noise, and rooms that never quite reach the thermostat setting. Damaged, dirt-loaded, or off-balance wheels force the blower motor to work harder, accelerating wear on the motor and bearings and driving up energy costs.

Installing the OEM Lennox 47K28 is important because blower wheels differ in blade count, pitch, diameter, and shaft bore. A generic substitute can move too little or too much air, overheat the motor, and run loud. The factory-correct part ensures proper fit, true balance, and smooth, quiet performance for your Lennox system.
