Lennox 98M91 Fan Blade
When you're troubleshooting a call for high vibration or reduced heat transfer, a compromised Lennox 98M91 is often the culprit. This OEM condenser fan blade is a critical replacement component for maintaining the static pressure and CFM requirements of commercial and residential Lennox, Armstrong, and Ducane units. Featuring a 22-inch diameter and a 2-blade configuration with a 26-degree pitch, this propeller is engineered for clockwise (CW) rotation (viewed from the discharge side) and mounts to a standard 1/2-inch motor shaft bore.
Replacing a warped or imbalanced 22-inch HVAC fan blade is mandatory to prevent premature motor bearing failure and ensure correct condenser airflow. Constructed from high-strength materials, this Lennox 100265-01 equivalent provides the precise aerodynamic profile needed to meet original factory performance specs. For technicians performing a condenser fan motor replacement, verifying the pitch and rotation is essential to avoid overloading the motor or reversing airflow, which can lead to high-head pressure trips.
- Direct OEM Compatibility: Precise fit for Lennox 98M91 and 100265-01, ensuring no modifications are needed to the motor height or shroud clearance.
- Optimized Airflow: The 26-degree pitch is calibrated to move the exact volume of air required for proper heat rejection at standard RPMs.
- Vibration Reduction: Factory-balanced 2-blade design minimizes mechanical stress on the motor shaft and reduces operational noise levels.
- Standardized Bore: Features a 1/2" hub diameter, compatible with most standard condenser motors used in high-efficiency Lennox equipment.
Common Questions
What is the correct rotation for the 98M91 fan blade?
This blade is designed for Clockwise (CW) rotation when looking at the air-discharge side. Always verify the rotation on the motor nameplate before securing the set screw.
Do I need a hub puller to replace this blade?
While a hub puller is the professional way to remove a rusted blade without bending the motor shaft, cleaning the shaft with emery cloth and using a penetrant is often sufficient for newer installations.
Can I use this on other HVAC brands?
Yes, as long as the 22-inch diameter, 2-blade count, 26-degree pitch, and CW rotation match the original specifications. It is frequently used for Allied, Armstrong, and Ducane service calls.
