Heatcraft Refrigeration D21194A2 Blade
The Heatcraft Refrigeration D21194A2 Fan Blade is a precision-engineered OEM replacement fan blade designed for high-efficiency air movement in commercial refrigeration and HVAC systems. Featuring a 12-inch diameter and a 19-degree pitch, this 5-blade aluminum propeller is optimized to maintain critical head pressure and ensure consistent evaporator coil airflow. For service technicians, the 5/16-inch bore and clockwise (CW) rotation make it a standard fit for specialized Heatcraft condensing units and reach-in coolers. Replacing a warped or unbalanced condenser fan blade is essential to protecting the compressor from overheating and preventing premature motor bearing failure. This 12-inch refrigeration fan blade provides the exact HVAC airflow performance required to meet original factory specifications, minimizing vibration and operational noise in the field. When sourcing heavy-duty fan blades, matching the pitch and bore size exactly is non-negotiable for maintaining system TESP (Total External Static Pressure) and overall energy efficiency.
Key Benefits- Optimized Airflow: The 19-degree pitch and 5-blade configuration provide superior CFM delivery for effective heat transfer.
- Direct Fit Compatibility: Specifically designed for Heatcraft units with a 5/16" motor shaft, ensuring a secure bore fit without the need for adapters.
- Durable Construction: Built with lightweight yet rigid materials to handle the high-static environments of commercial refrigeration fans.
- Quiet Operation: Precision balance reduces mechanical resonance, extending the life of the fan motor and reducing site noise.
- How do I determine the correct rotation? Rotation is determined by looking at the discharge side of the blade. This model is Clockwise (CW) rotation.
- Can I use this on a 1/2" shaft? No, this blade features a fixed 5/16" bore size and is only compatible with matching motor shafts.
- Why is the 19-degree pitch important? The pitch directly impacts the amp draw of the motor; using the wrong angle can lead to motor overload or insufficient cooling.
