Sterling J34R06999-104 Fan Blade

The Sterling J34R06999-104 Fan Blade is a critical OEM replacement component designed for high-efficiency air movement in Sterling and Beacon Morris unit heaters. This heavy-duty 16-inch diameter fan blade is engineered with a 33-degree pitch and 4-blade configuration to maintain specific CFM requirements. Constructed for precision balance, it features a clockwise (CW) rotation and is designed to fit a standard 1/2 inch bore motor shaft. This propeller is commonly found in TF series unit heaters, providing the necessary static pressure to move air across the heat exchanger safely and effectively.

For technicians performing a Sterling heater fan blade replacement, verifying the pitch and rotation is vital to avoid motor overload or reduced thermal efficiency. The J34R06999-104 offers a direct fit for models manufactured both before and after 2007 (verify specific serial ranges), ensuring the fan assembly operates within the original design parameters. Using an OEM HVAC fan blade like this 16" 33-degree propeller ensures the unit maintains its rated BTU output without causing excessive vibration or premature HVAC blower motor failure.

• Precision Airflow: The 33-degree pitch is calibrated for maximum heat transfer efficiency in industrial unit heaters.
• OEM Compatibility: Direct replacement for Sterling 11J34R06999-104 and can supersede J34R05944 in certain applications.
• Industrial Build: Durable 4-blade aluminum construction resists corrosion and maintains structural integrity under high RPM.
• Standardized Fit: Featuring a 1/2" bore, it installs quickly on standard unit heater motors.

• How do I confirm the rotation? This blade is CW (Clockwise) rotation. Always determine the rotation by looking at the discharge side (the direction of airflow).
• Will this fit other brands? While designed for Sterling and Beacon Morris, it may cross-reference with Lau 6148300001 if the 16" diameter and 33-degree pitch match.
• What if my motor has a different shaft size? This blade is specifically bored for a 1/2 inch shaft; if your motor has a 5/8" shaft, this model will not be compatible.
