Lennox 67M37 Fan Blade
The Lennox 67M37 Fan Blade is a critical replacement component designed for high-efficiency condenser units and commercial HVAC systems. Engineered for durability, this condenser fan blade features an 18-inch diameter with a 3-blade configuration, optimized for maximum CFM output while maintaining stable static pressure. It is precision-balanced to reduce vibration, extending the service life of the fan motor and maintaining system integrity. Built with a 1/2-inch bore, it ensures a secure fit on standard motor shafts. The clockwise (CW) rotation is essential for proper airflow direction across the coils, facilitating effective heat transfer. This OEM-spec blade is crucial for HVAC maintenance, particularly in systems where Lennox replacement parts are specified to meet original engineering tolerances. When replacing, verify the pitch degree and bore size to ensure optimal performance and avoid unnecessary motor load in demanding environmental conditions.
Key Benefits
- Precision Balance: Reduces mechanical stress on the condenser motor bearings to prevent premature failure.
- Optimal Airflow: The 3-blade design provides a high-volume CFM rating to ensure efficient thermal exchange.
- Corrosion Resistance: Engineered with materials capable of withstanding harsh outdoor environments.
- Direct Compatibility: Designed specifically for Lennox HVAC systems, ensuring exact physical and performance specifications.
Common Questions
What is the correct rotation for the 67M37?
This fan blade is designed for clockwise (CW) rotation when viewed from the discharge side. Confirming rotation is critical to avoid reversing airflow.
Will this blade fit a 5/8-inch motor shaft?
No, this unit features a 1/2-inch hub bore. Attempting to modify the bore will compromise the balance and integrity of the blade.
When should I replace my condenser fan blade?
Replacement is necessary if you notice stress cracks, excessive vibration, or significant oxidation that could lead to catastrophic blade failure during high-load periods.
