Lennox 98M18 Fan Blade

For veteran technicians servicing Lennox, Armstrong, or Ducane condenser units, the Lennox 98M18 Fan Blade (also identified as 98M1801) is an essential OEM replacement for restoring peak static pressure and airflow. This 18-inch diameter, 3-blade propeller features a 1/2-inch bore and a fixed hub located on the intake side (opposite discharge). Engineered with a 27-degree pitch, this condenser fan blade replacement ensures the precise cubic feet per minute (CFM) required for optimal heat transfer across the coil. Designed for a counter-clockwise (CCW) rotation when facing the discharge side, the Lennox 98M18 provides a direct fit for a vast range of residential systems, including popular models like the 10HPB24-1P and 13ACXN-series. Using a genuine Lennox HVAC part vs. a generic alternative prevents premature motor bearing wear and maintains the integrity of the system's factory-rated performance levels.

• Precise Airflow Dynamics: The 27-degree pitch is specifically calibrated for 18-inch HVAC fan blade applications to maximize efficiency.
• Universal Compatibility: This 1/2-inch bore unit serves as a direct replacement for both 98M18 and 98M1801 part numbers.
• Rugged Construction: Built to withstand high-velocity outdoor environments in standard Lennox and Ducane condensing units.
• Seamless Installation: Features a fixed hub design for secure attachment to the motor shaft without the need for additional specialized adapters.

Is the 98M18 identical to the 98M1801?
Yes, these two part numbers are interchangeable. The 98M18 is the common replacement identifier for the original 98M1801 Lennox fan blade.

How do I confirm the rotation of my existing blade?
This blade is rated for counter-clockwise (CCW) rotation as viewed looking at the air discharge side. Verify your condenser motor rotation before securing the hub.

What is the best way to pull the old blade?
To avoid damaging the motor shaft, a professional fan blade puller is recommended, especially on older Lennox 18-inch fan assemblies where corrosion may have bonded the hub to the 1/2-inch shaft.
