Nordyne 667294R Blower Wheel

The Nordyne 667294R Blower Wheel is a precision-engineered OEM replacement part designed for high-static pressure applications in residential and light commercial HVAC systems. Featuring a 9.5-inch diameter and a 7.5-inch width, this double inlet blower wheel is specifically balanced to maintain optimal cubic feet per minute (CFM) delivery while minimizing vibration-induced motor stress. This unit operates with a clockwise (CW) rotation and is equipped with a standard 1/2-inch bore, ensuring direct compatibility with shared Nordyne, Nortek, and Miller furnace and air handler assemblies. Utilizing heavy-duty galvanized steel construction, this wheel resists corrosion and blade deformation during high-velocity operation. When diagnosing restricted airflow or excessive mechanical noise, replacing an imbalanced or fouled wheel with this genuine HVAC blower component restores factory-spec static pressure and system efficiency. Contractors should verify the rotation and shaft diameter before installation to ensure a drop-in fit for specific gas and electric furnace models.

Key Benefits

• Optimized Airflow Performance: Specifically pitched blades provide stable 9.5x7.5 performance metrics to meet strict furnace airflow requirements.
• Vibration Reduction: Factory-balanced design prevents premature bearing failure in the blower motor.
• Direct OEM Compatibility: Engineered as a drop-in replacement for the Nordyne 667294R part number, eliminating the need for housing modifications.
• Industrial-Grade Construction: Built with high-quality materials to withstand the thermal stress of continuous heating and cooling cycles.
• Efficient Hub Integration: The 1/2" bore size with integrated setscrew allows for a secure, slip-free connection to the motor shaft.

Common Questions

Is the rotation of this wheel reversible?
No, this is a dedicated clockwise (CW) rotation wheel. Attempting to reverse the rotation will result in significant loss of static pressure and potential motor overheating.

What are the exact dimensions for housing clearance?
This wheel measures 9.5 inches in diameter and 7.5 inches in width. Ensure your blower housing provides adequate clearance for these specific dimensions to prevent rubbing or noise issues.

How do I confirm this fits my specific furnace model?
You should match the 667294R part number against your unit's parts list. This wheel is commonly found in Nordyne-produced equipment branded under several names, including Miller and Intertherm.
