Lennox 24L20 Fan Blade
The Lennox 24L20 Fan Blade is a precision-engineered condenser fan blade designed for high-performance heat transfer in residential and light commercial HVAC units. Featuring a 20-inch diameter and a 30-degree pitch, this 4-blade aluminum assembly is optimized for maximum CFM output while maintaining structural integrity under high static pressure. Engineered for CW rotation (clockwise) with a standard 1/2-inch bore, it serves as a direct replacement for numerous Lennox condenser units and Armstrong Air systems. As a critical component of the outdoor fan motor assembly, it ensures efficient refrigerant cooling by facilitating consistent airflow across the condenser coils. Its robust construction resists corrosion and prevents blade deformation, common issues that lead to system vibration and motor bearing premature wear. Technicians should verify the hub location and set screw alignment during installation to ensure dynamic balance and quiet operation within the shroud.
Key Technical Benefits- Optimized Airflow Efficiency: The 30-degree pitch is calibrated to move high volumes of air, essential for maintaining proper head pressure in Lennox HVAC systems.
- Durable Aluminum Construction: Lightweight yet rigid replacement fan blade design reduces the starting torque requirement on the condenser fan motor.
- Universal HVAC Compatibility: Features a standard 1/2" bore size, making it compatible with a wide range of OEM and aftermarket motors.
- Vibration Reduction: Factory-balanced 4-blade configuration minimizes mechanical stress on the motor shaft and prevents cabinet rattling.
Is the Lennox 24L20 compatible with all 20-inch condenser fans?
While the 20-inch diameter is standard, compatibility depends on the 30-degree pitch, CW rotation, and 1/2" bore. Always verify the orientation (Clockwise facing the intake) before fitting.
What causes this fan blade to require replacement?
Common failure points include blade stress fractures, hub corrosion, or damage from hail and debris. Replacing a bent blade is critical to prevent HVAC compressor overheating and motor failure.
Does this blade include the hub set screw?
Yes, this OEM replacement part typically includes the integrated hub and set screw for secure mounting to the motor shaft.
