Aaon R17840 Fan Blade

The Aaon R17840 Fan Blade is a critical OEM replacement part for technicians maintaining commercial condensers and air handling units. This 22-inch diameter propeller is precision-engineered with a three-blade configuration and a 29-degree pitch to deliver high-volume airflow while minimizing motor load and vibration. Built for durability in demanding HVACR environments, the R17840 features a standard 1/2" bore and is designed for clockwise (CW) rotation. When performing a condenser fan motor repair, utilizing this genuine Aaon component ensures the static pressure and CFM ratings remain within factory specifications, preventing premature compressor wear or high-head pressure trips. This HVAC ventilation fan is balanced to industrial standards, offering a reliable solution for restoring system efficiency and maintaining optimal heat transfer across the coils. For contractors seeking direct-fit HVAC parts, the R17840 provides the exact mechanical tolerances required for seamless integration with existing Aaon equipment drive shafts.

• Precision Airflow: The 29-degree pitch angle is optimized for maximum CFM and efficient heat dissipation in commercial cooling applications.
• OEM Compatibility: As a genuine Aaon fan blade, it eliminates the balancing issues and alignment risks associated with generic aftermarket propellers.
• Reduced Mechanical Stress: The 3-blade design is engineered to reduce rotational noise and bearing wear on the condenser motor.
• Rugged Construction: Designed to withstand high-static pressure and harsh environmental exposure without deforming or losing pitch accuracy.

• How do I confirm the rotation of my old blade? Check the rotation from the discharge side or the end of the motor shaft; the R17840 is strictly a clockwise (CW) rotation component.
• Will this fit a 5/8" motor shaft? No, this part is specifically manufactured with a 1/2 inch bore; always verify your motor shaft diameter before installation.
• Is balancing required before installation? No, these HVAC replacement blades are factory-balanced to ensure smooth operation immediately upon secure mounting.
