Lennox 72L75 Fan Blade

Lennox 72L75 Fan Blade

Ensure reliable condenser heat rejection with the Lennox 72L75 Fan Blade, a precision-engineered OEM replacement part designed for high-performance Lennox condensing units. This 18-inch diameter fan blade features a robust 3-blade configuration with a 30-degree pitch, optimized to provide consistent airflow and maintain proper head pressure in demanding outdoor environments. Built with a durable steel spider and riveted propeller blades, it is balanced to reduce vibration and extend the service life of the condenser fan motor. The 1/2-inch bore includes a fixed hub and a single set screw for secure mounting on standard motor shafts. Designed for clockwise (CW) rotation facing discharge, this Lennox 20391102 equivalent ensures a perfect fit for a wide range of Lennox, Armstrong, and Ducane residential systems, restoring original cooling capacity and system efficiency for your next service call.

Key Benefits
  • Optimized Airflow: The 30° blade pitch is specifically calibrated for efficient heat exchange and improved system SEER ratings.
  • Industrial-Grade Construction: Features a corrosion-resistant finish and heavy-duty steel spider for long-term outdoor exposure.
  • Vibration Reduction: Precision-balanced riveted design minimizes mechanical stress on motor bearings and reduces operational noise.
  • Direct OEM Fit: Drop-in replacement for part numbers 72L75, 72L7501, and 20441502, eliminating the need for field modifications.
Common Questions
  • What is the correct rotation for this blade? This unit is designed for Clockwise (CW) rotation when looking at the air discharge side. Always verify your motor's rotation before installation.
  • How do I ensure proper blade depth? To maintain optimal static pressure, align the blade within the venturi shroud as per the original equipment manufacturer's specifications—typically centered in the orifice.
  • Will this fit a 5/8" motor shaft? No, this blade is specifically machined for a 1/2" diameter motor shaft. Attempting to modify the bore will void the balance and performance profile.
