Why Choose Genuine Carrier OEM?

For large-format blower wheels, precision balance is the most critical factor for system longevity. An unbalanced wheel of this size creates massive mechanical vibrations that can lead to catastrophic motor bearing failure and structural damage to the blower housing. This wheel is factory-calibrated for vibration-free rotation, ensuring reliable performance and protecting your equipment investment.

Pro-Tech Installation Tip: This blower wheel is designed for a 1-7/16" motor shaft. Before mounting, thoroughly clean the motor shaft of any rust or oxidation with a light abrasive to allow the hub to seat easily. Ensure the set screw is tightened firmly against the flat portion of the shaft to prevent slippage during high-torque startup. Always spin the wheel by hand after installation to verify it has full clearance within the blower housing before restoring power to the unit.
