Lennox 98M19 Fan Blade

As a veteran HVAC technician, I know that maintaining precise airflow is non-negotiable for system longevity. The Lennox 98M19 Fan Blade is a genuine OEM condenser fan blade replacement engineered for high-static pressure environments. This 18-inch 4-blade fan features a 27-degree pitch and is balanced to eliminate the vibration issues that commonly lead to premature motor bearing failure. Designed for CCW rotation (counter-clockwise facing discharge), this Lennox HVAC 98M19 part ensures your unit pulls heat from the coils efficiently, preventing compressor overheating during peak summer loads.

The Lennox 98M19 is a direct replacement for legacy part numbers such as Lennox 100060-08 and Allied R20391110. Built with a 1/2 inch bore and a fixed hub, it integrates seamlessly with standard condenser motors found in Lennox, Armstrong, and Ducane equipment. Whether you are performing a routine overhaul or emergency HVAC fan blade repair, sticking with OEM technical specifications ensures the CFM output remains within the manufacturer’s original design parameters.

• OEM Compatibility: Exact fit for Lennox, Armstrong, and Ducane condenser units requiring an 18" prop.
• Precision Balance: The 4-blade, 27-degree pitch design reduces mechanical stress on the motor shaft.
• Durable Construction: High-grade steel blades riveted for industrial-strength performance.

• Standardized Bore: 1/2" fixed hub allows for a secure fit on standard motor shafts.

Common Questions

What is the correct rotation for the Lennox 98M19?
This blade is designed for Counter-Clockwise (CCW) rotation when facing the discharge side. Always verify your motor’s rotation before installation to ensure proper heat rejection.

Will this fan blade fit my specific Lennox unit?
The 98M19 is a widely used 18-inch propeller. It replaces part numbers 100060-08, 68J27, and R100060-08. Check your existing blade’s pitch and diameter to confirm the 18" 27-degree spec matches.

Why is my condenser fan blade vibrating?
Vibration is often caused by a bent blade or debris accumulation. Replacing an unbalanced blade with a factory-spec 98M19 prevents permanent damage to the condenser motor.
