Sterling HVAC 11J34R06999-003 Fan Blade
The Sterling HVAC 11J34R06999-003 Fan Blade is a critical OEM replacement component engineered for high-performance air movement in gas-fired unit heaters and ventilation systems. This 12-inch 5-blade fan features a clockwise (CW) rotation and is precision-balanced to maintain system pressure and CFM output. Designed with a 3/8-inch bore, it ensures a secure fit on standard motor shafts, effectively eliminating vibration issues that lead to bearing wear. Built for industrial durability, this condenser and heater fan blade is compatible with Beacon Morris, Mestek, and Sterling unit heaters, including HSA and HSB series models manufactured both before and after 2007. Utilizing an air drive AD12CW34 configuration, it provides a direct cross-reference for the J34R00321-001 fan blade. For technicians performing HVAC motor maintenance, this part is essential for restoring optimal airflow and preventing motor overheating in commercial heating environments.
Key Benefits- Broad Compatibility: Direct OEM replacement for Sterling and Beacon Morris unit heaters, streamlining inventory for service calls.
- Optimized Airflow: The 5-blade design maximizes static pressure and air distribution for better thermal exchange.
- Precision Engineering: Balanced 12" fan diameter reduces torque stress on the motor, extending the life of the drive system.
- Secure Installation: The 3/8" bore provides a precise mechanical connection for high-RPM operation.
What is the correct rotation for this fan blade?
This model is designed for clockwise (CW) rotation. Always verify the rotation from the lead end of the motor to ensure proper airflow direction.
Which heater models use the 11J34R06999-003?
It is commonly found in Sterling HSA13611 and HSB04811 units, as well as equivalent Beacon Morris models like the HBA and HBB series.
Can this replace a blade with a different bore size?
No, this unit is specifically machined for a 3/8-inch shaft. For different shaft diameters, a matching bore size or specialized adapter is required to prevent shaft damage.
