Lennox 98M20 Fan Blade

The Lennox 98M20 Condenser Fan Blade is a heavy-duty 18-inch HVAC replacement fan engineered for high-static pressure applications in residential and light commercial condensing units. This specialized 4-blade riveted propeller features a precise 34-degree pitch, optimized to maintain high-velocity airflow while reducing motor load. Designed with a 1/2-inch bore and a fixed hub, this component is a direct drop-in for Lennox technical specs requiring counterclockwise (CCW) rotation facing the discharge side. The steel spider construction provides the structural integrity needed to prevent blade deflection under heavy load, ensuring long-term balance and whisper-quiet operation in demanding outdoor environments. As a veteran-grade OEM replacement part, this unit offers cross-compatibility with several legacy Lennox, Armstrong, and Ducane part numbers, making it a versatile addition to any technician's truck stock for emergency cooling repairs. This part is functionally identical to Lennox 98M2001 and Allied 68J2801.

• Optimized Airflow: The 34° blade pitch is factory-calibrated to deliver maximum CFM for efficient heat rejection.
• Precise Balance: Riveted steel construction reduces vibration, protecting the condenser fan motor bearings from premature wear.
• Broad Compatibility: Replaces multiple obsolete part numbers including 68J2801, 98M2001, 68J28, and 100060-09.
• Durable Engineering: Designed with a steel spider and high-grade aluminum blades to resist corrosion in harsh outdoor conditions.

What is the correct rotation for the 98M20?
This blade is designed for CCW (Counterclockwise) rotation when facing the discharge side. Always verify the motor rotation before installation to ensure proper airflow direction across the coil.

Will this fit a 1/2" motor shaft?
Yes, this fan blade features a standard 1/2" bore with a set screw, making it compatible with most standard condenser fan motor shafts in this size class.

Can I use this to replace a 3-blade fan?
It is recommended to match the original blade count, diameter, and pitch exactly. Switching from a 3-blade to a 4-blade fan blade can change the amp draw on your motor; always check the motor's FLA (Full Load Amps) after replacement.
