Lennox 72L87 Fan Blade

The Lennox 72L87 Fan Blade is a critical HVAC replacement part designed for high-efficiency air movement in condenser units and air handlers. This 22-inch diameter fan blade features a precision-engineered 3-blade configuration with a 21-degree pitch to ensure optimal CFM performance while maintaining a balanced, low-vibration operation. It is built with a 0.5-inch bore and a fixed hub, specifically designed for CW facing discharge (clockwise rotation) to meet the demanding airflow requirements of Lennox residential and commercial systems.

As a direct OEM specification, the 72L87 is identical to 72L8701, providing a seamless drop-in solution for contractors performing field repairs. Constructing the assembly from heavy-duty materials, this Lennox condenser fan blade is engineered to withstand environmental exposure and mechanical stress. Using a genuine OEM Lennox 72L87 ensures that the motor remains within its designated torque range, preventing premature motor failure caused by off-spec aftermarket blade weight or pitch imbalances.

• Precision Airflow: The 22" 3-blade design and 21-degree pitch provide consistent static pressure and efficient heat exchange.
• Direct OEM Compatibility: Replaces 72L8701 and 20391106 without requiring modification to the motor shaft or housing.
• Reduced Vibration: Factory-balanced construction minimizes mechanical noise and bearing wear on the fan motor.
• Industrial Durability: Solid hub and rigid blade design prevent flexing under high-load cooling cycles.

Is the Lennox 72L87 interchangeable with the 72L8701?
Yes, the 72L87 and 72L8701 are identical parts with the same technical specifications, diameter, and bore size.

What is the rotation direction for this fan blade?
This specific model is designed for clockwise (CW) facing discharge. Always verify rotation from the discharge side before installation.

Will this fit any 1/2 inch motor shaft?
While the 0.5-inch bore is a standard size, this blade is specifically pitched for Lennox performance envelopes. Confirming the 22-inch clearance and motor horsepower is recommended to avoid overloading the drive.
