Lennox 71W99 Blade
The Lennox 71W99 is a high-performance 3-blade condenser fan blade engineered for heavy-duty HVACR applications. This OEM Lennox fan blade features a 23.5-inch diameter and a 26-degree pitch, specifically calibrated to optimize airflow across condenser coils in residential and commercial outdoor units. With a 1/2-inch bore and clockwise (CW) rotation, the 71W99 ensures a secure fit on standard motor shafts, maintaining the static pressure requirements necessary for efficient heat exchange. Constructed with a steel spider and riveted aluminum blades, this replacement condenser fan blade (also cataloged as 100654-02) provides the structural integrity needed to prevent blade flex and vibration during high-RPM operation. Professional technicians prioritize this 23-1/2" diameter fan blade to restore system factory specifications, ensuring the compressor operates within safe thermal limits while reducing amp draw on the fan motor.
Key Benefits
- Precision Airflow: The 26-degree blade pitch is engineered to move the exact CFM required for Lennox KHB, LGM, and premium condensing models.
- Vibration Dampening: Features a steel spider hub that minimizes harmonic resonance, extending the life of the motor bearings.
- OEM Compatibility: Replaces the Lennox 100654-02 and 100654-05, ensuring a drop-in fit without the need for shaft modifications.
- Durable Construction: Riveted propeller design withstands harsh outdoor environments and constant cycling.
Common Questions
What is the correct rotation for the Lennox 71W99?
This blade is designed for clockwise (CW) rotation when facing the discharge side (looking at the air leaving the unit).
Will this blade fit a 5/8-inch motor shaft?
No, the 71W99 is strictly a 1/2-inch bore. For 5/8-inch applications, a different part number or a reducing bushing is required, though OEM replacement is recommended.
How do I verify if this 23.5-inch blade is compatible with my unit?
Always check the data plate on the blower housing or the original blade. This 3-blade fan is a specific match for Lennox 71W99 and Revcor 100654-02 specifications.
