Sterling HVAC 11J34R06999-007 Fan Blade

The Sterling HVAC 11J34R06999-007 Fan Blade is a critical OEM replacement propeller designed for precise airflow management in residential and commercial heating units. Constructed from high-grade aluminum, this 14-inch diameter fan blade features a 5-blade configuration optimized for the Sterling HSB series and compatible Beacon Morris unit heaters. Engineered with a 3/8 inch bore and a clockwise (CW) rotation, it ensures exact balance and reduced vibration, preventing premature motor bearing wear. Whether you are servicing a horizontal steam or hot water unit heater, this Sterling unit heater fan blade provides the structural integrity required to maintain static pressure and peak thermal exchange. As an authentic Mestek replacement part, it eliminates the pitch and fitment issues often found in generic hub-and-blade assemblies, ensuring a seamless field installation for HVAC technicians.

• Optimized Airflow: The 5-blade aluminum design maximizes CFM output while maintaining low decibel levels during high-load operation.
• Precision Tolerance: Features a factory-set 3/8" bore and hub assembly for direct mounting to OEM motor shafts without modification.
• System Longevity: Lightweight aluminum construction reduces rotational mass, extending the service life of the blower motor.
• Broad Compatibility: Matches technical specifications for Sterling HSB08411, GG075, and QVF060 models manufactured after June 2007.

What is the direction of rotation for this blade?
This specific model is designed for clockwise (CW) rotation as viewed from the discharge side to ensure correct air throw across the heat exchanger.

Will this fan blade fit older Sterling unit heaters?
The 11J34R06999-007 is typically utilized in units built after mid-2007. For older GG or HS series, verify the bore size and diameter, as earlier production runs may utilize different hub offsets.

Does this include the set screw for the motor shaft?
Standard Sterling HVAC replacement fan blades generally include the integrated hub set screw, but it is recommended to inspect the existing motor shaft for scoring before securing the new propeller.
