Aaon P86780 Fan Blade

The Aaon P86780 Fan Blade is a precision-engineered 26-inch condenser fan blade designed for high-performance heat dissipation in commercial HVAC systems. This heavy-duty replacement part features a 30-degree pitch and a 1/2-inch bore diameter, ensuring optimal airflow across the condenser coils to maintain system head pressure and efficiency. The P86780 serves as the direct replacement for 28877, allowing for seamless integration into existing Aaon rooftop units and air-cooled chillers without the need for field modifications or shaft adaptations. Constructed for long-term durability in demanding outdoor environments, this blade is balanced to minimize vibration, reducing mechanical stress on the fan motor and bearings. For contractors performing preventative maintenance or emergency repairs, verifying the fan blade rotation and pitch is critical to restoring factory-rated cooling capacity. This OEM HVAC replacement part ensures your system operates within original design parameters while preventing premature compressor failure due to insufficient airflow.

• Precise 30-Degree Pitch: Engineered to maximize CFM output while balancing amp draw on the condenser fan motor.
• Direct OEM Interchange: Specifically designed to replace obsolete part number 28877 for a drop-in fit on Aaon equipment.
• Bore Specifications: Standard 1/2-inch bore compatible with common commercial motor shaft sizes.
• Rigid Construction: Built to withstand high-velocity air movement and variable static pressures typical of industrial applications.

Common Questions

What is the primary application for the Aaon P86780?
This blade is primarily used in commercial condenser sections where a 26-inch diameter and specific 30-degree pitch are required to meet heat exchange requirements.

Can I use the P86780 to replace part number 28877?
Yes, the P86780 is the manufacturer-designated direct replacement for the 28877, maintaining identical physical and performance specifications.

Is the bore size adjustable for different motor shafts?
