Lennox 76K01 Blower Wheel

The Lennox 76K01 Blower Wheel is a high-performance 10x10 centrifugal fan wheel specifically engineered for direct drive blower assemblies in Lennox, Allied, and Armstrong HVAC systems. Measuring exactly 10 inches in diameter by 10 inches in width with a 1/2 inch bore, this OEM replacement wheel ensures precise balance and optimal airflow, directly impacting the static pressure and efficiency of the air handler. Featuring a clockwise (CW) rotation and a secured hub-end set screw, this double-inlet blower wheel is designed to reduce motor strain and cabinet vibration. This component is the primary solution for Lennox 76K01 replacement needs and serves as a verified sub-component for several legacy parts, including R02592A006 and R76728200. For technicians servicing G75 and G78 furnace series or 12GCS package units, maintaining the assembly with this galvanized steel blower wheel is critical for preventing premature motor failure and ensuring peak CFM delivery across the ductwork system.

• Precision Balanced: Factory-balanced design minimizes HVAC vibration and noise, protecting the blower motor bearings from excessive wear.
• Universal Compatibility: Serves as a direct replacement for Lennox R76728200, R02592A006, and 28M90, ensuring a seamless drop-in fit.
• High-Volume Airflow: The 10" x 10" blower wheel geometry is optimized for direct drive systems to maintain consistent indoor air quality and system efficiency.
• Durable Infrastructure: Constructed for industrial and commercial use, handling the high-torque demands of constant-speed furnace motors.

• What are the symptoms of a failing blower wheel? Technicians usually identify a failing 76K01 by excessive "thumping" sounds, reduced airflow at the registers, or visible debris buildup in the squirrel cage fins which can cause motor overheating.
• Does this wheel include the mounting hardware? This 1/2 inch bore blower wheel includes the integrated set screw required to lock the wheel onto the motor shaft.
• Which rotation is the 76K01? This is a Clockwise (CW) rotation wheel, viewed from the hub/shaft end. Always verify the rotation of the existing motor before installation to prevent system back-pressure.
