Lennox 46K13 Fan Blade

For HVACR contractors maintaining Lennox condensing units, the Lennox 46K13 Fan Blade is a direct OEM replacement engineered for high-volume airflow and precise balance. This 20-inch diameter HVAC fan blade features a 4-blade configuration with a 24-degree pitch, designed specifically to maintain optimal head pressure in outdoor condenser sections. Built with a 1/2-inch bore, it ensures a secure fit on standard motor shafts, effectively eliminating the vibration issues often associated with generic aftermarket alternatives.

The Lennox 46K13 is technically identical to part number 46K1301 and serves as a critical condenser fan blade replacement for various residential and commercial models. Utilizing a CW (Clockwise) rotation, this component is constructed from heavy-duty materials to resist the structural fatigue caused by continuous outdoor operation. For technicians performing a Lennox AC fan motor repair, verifying the pitch and rotation is essential to prevent motor overheating and ensure the system meets its rated SEER efficiency. This blade provides the exact OEM specifications required to restore factory-standard cooling performance.

• Precision Balanced: Engineered to reduce mechanical stress on the fan motor bearings, extending the service life of the entire drive assembly.
• Direct OEM Match: Fully compatible with systems requiring part numbers 46K13, 46K1301, 41518001, and R41518-001.
• Optimized Airflow: The 24-degree blade pitch maximizes CFM output while maintaining quiet operation in high-demand environments.
• Durability: High-grade construction resists corrosion and deformation under extreme thermal cycling and UV exposure.

• Does this blade include the set screw? Yes, most 46K13 assemblies include the necessary hardware to secure the 1/2" hub to the motor shaft.
• What is the rotation direction? This is a Clockwise (CW) rotation blade. Always verify rotation from the discharge side (top) before installation.
• Can I use this if my original part is 46K1301? Absolutely. The 46K13 and 46K1301 are the same technical component with identical performance metrics.
