Greenheck 820546 Wheel Assembly
The Greenheck 820546 Wheel Assembly is a precision-engineered G95 centrifugal blower wheel designed for high-performance air movement in commercial ventilation systems. This galvanized steel blower wheel features a 9.5-inch diameter and is bored for a 1/2 inch shaft diameter, ensuring a secure fit on standard motor spindles. As a direct OEM Greenheck replacement part, it maintains the structural integrity and airflow characteristics required for Greenheck G-series centrifugal roof exhausters. The forward-curved blade geometry is optimized for quiet operation and efficient static pressure development. This exhaust fan wheel assembly is dynamically balanced to reduce vibration, extending the bearing life of your drive assembly. When performing a field replacement, verify the rotation direction and set screw alignment to ensure peak performance. This assembly is standard hardware for maintaining HVAC blower wheel efficiency in demanding restaurant and laboratory exhaust applications where consistent CFM delivery is critical.
- OEM Compatibility: Exact drop-in replacement for Greenheck G-series fans, ensuring zero-clearance issues during installation.
- Corrosion Resistance: Heavy-gauge galvanized construction protects against moisture and environmental degradation in rooftop settings.
- Precision Balancing: Factory-balanced to eliminate oscillation, reducing mechanical stress on the motor and drive belt.
- Optimized Airflow: Forward-curved design provides high-volume output at lower RPMs for improved acoustic performance.
Frequently Asked Questions
What is the bore size for the Greenheck 820546?
This specific wheel assembly is machined for a 1/2 inch diameter shaft. Always measure the motor or fan shaft with a micrometer before ordering to ensure a proper press fit.
Is this wheel assembly compatible with other fan brands?
While designed as a Greenheck 820546 replacement, it may fit other 9.5-inch centrifugal fans. However, contractors should verify rotation, width, and hub protrusion to prevent motor overloading or housing interference.
How do I ensure the new wheel is installed correctly?
Ensure the set screws are seated on the shaft flat. It is recommended to check the fan's RPM against the G95 wheel specifications to prevent catastrophic failure from over-speeding.
