Greenheck 335304 Blower Wheel
The Greenheck 335304 Blower Wheel is a precision-engineered centrifugal blower wheel designed for specific HVAC ventilation applications, such as the Greenheck SP-A series ceiling exhaust fans. Constructed from high-grade, glass-reinforced plastic blower wheel material, this component offers superior corrosion resistance and reduced rotational mass compared to traditional galvanized steel alternatives. It features a CW (Clockwise) rotation as viewed from the drive end and is designed with a 1/2 inch bore to ensure a secure fit on standard motor shafts. For technicians performing a Greenheck exhaust fan repair, this wheel is essential for maintaining original CFM ratings and static pressure performance. The forward-curved fin geometry is optimized for quiet operation and efficient airflow delivery in commercial air handling environments. When replacing a ventilation fan impeller, verify the diameter and width match the existing housing dimensions to prevent mechanical interference or motor overload during startup.
Key Benefits
- Precision Balanced: Factory-set balancing reduces vibration, extending the life of the motor bearings and minimizing noise.
- Corrosion-Resistant Polymer: High-density plastic construction prevents rust and degradation in high-humidity airflow streams.
- OEM Specific Design: Ensures exact compatibility with Greenheck SP-A110 through SP-A190 models for seamless drop-in replacement.
- Reduced Motor Load: Lightweight material composition requires lower starting torque, improving overall drive efficiency.
Common Questions
Is the Greenheck 335304 compatible with other fan brands?
While designed primarily for Greenheck SP-A series units, this centrifugal fan wheel may fit other housings provided the 1/2 inch bore, CW rotation, and physical diameter specs align. Always measure your existing wheel before installation.
What causes a plastic blower wheel to fail?
Most damage occurs due to excessive debris buildup, high temperature exposure beyond thermal limits, or set-screw slippage causing the hub to wallow out. Regular inspection of the fan impeller is recommended during seasonal maintenance.
How do I ensure the CW rotation is correct?
Check the rotation by looking at the intake side of the wheel. The blades must "scoop" the air into the discharge. This specific 335304 model is engineered for clockwise rotation only.
