Daikin-McQuay 667996502 Blower Wheel
The Daikin-McQuay 667996502 Blower Wheel is a high-performance tangential blower wheel engineered for critical airflow management in commercial HVAC systems, specifically within PTAC units and high-capacity fan coil units. Featuring a 28.6-inch diameter by 4.4-inch width, this crossflow blower wheel is constructed from galvanized metal to ensure structural integrity under continuous operation. The counter-clockwise (CCW) rotation, as viewed from the motor end, is designed to integrate seamlessly with the internal static pressure requirements of Daikin-McQuay air handlers. This OEM replacement fan wheel provides a precise fit on the motor spindle, minimizing balance issues and vibration that can lead to premature motor bearing wear. By maintaining the correct centrifugal fan geometry, this component restores original airflow volume and system efficiency in 1.25-ton cooling applications. Whether you are addressing restricted air movement or loud mechanical rattling, this replacement blower assembly is the standard for maintaining HVAC system performance.
Key Benefits:
- Precision Air Distribution: Designed as a tangential fan wheel to provide uniform air velocity across the entire 4.4" width of the cooling coil.
- Durable Galvanized Construction: Built to withstand commercial duty cycles, replacing the older 669660901 plastic wheel variations for increased longevity.
- Optimized Compatibility: Specifically balanced for Daikin PTAC units and McQuay fan coils, ensuring drop-in replacement without field modifications.
- Acoustic Performance: Reduced vibration profiles help eliminate common humming or rattling noises associated with unbalanced or deformed squirrel cage fans.
Common Questions:
What are the signs that my blower wheel needs to be replaced?
Technicians should look for uneven airflow, excessive vibration at the motor mount, or "thumping" sounds. Physical inspection often reveals warped blades or debris buildup that throws the impeller wheel out of balance.
Is this wheel compatible with older plastic models?
Yes, the 667996502 metal blower wheel is the direct engineering replacement for the legacy 669660901 plastic blower wheel, offering superior heat resistance and structural stability.
What is the correct rotation for this part?
This part is CCW (Counter-Clockwise) rotation. Always verify the rotation matches your specific motor and housing configuration to ensure proper static pressure and air discharge.
