Carrier LA22LA118 Wheel

The Carrier LA22LA118 is a heavy-duty, double-inlet centrifugal blower wheel engineered for high-static pressure applications in residential and light commercial HVAC systems. This genuine OEM blower wheel measures 11 1/8 inches in diameter with a 10 5/8-inch width, featuring a clockwise (CW) rotation configuration as viewed from the drive end. Constructed from corrosion-resistant galvanized steel, the blades are precision-balanced to eliminate vibration, reducing mechanical stress on the blower motor and ensuring quiet operation under load. This specific HVAC replacement wheel is a critical component for maintaining target airflow (CFM) across the evaporator coil, preventing liquid slugging and maintaining system efficiency. Designed for a 1/2-inch shaft diameter with a secure concave hub, it serves as a direct drop-in for numerous Carrier, Bryant, and Payne furnace and fan coil assemblies where replacement blower assembly parts are required for structural integrity and reliable air delivery.

Key Performance Benefits

• Precision Balance: Factory-calibrated to minimize shaft wobble and extend the bearing life of your fan motor.
• Industrial Construction: Galvanized steel fins provide necessary rigidity to prevent blade deformation during high-RPM cycles.
• Optimized Airflow: The 11 1/8" x 10 5/8" footprint is engineered for specific static pressure requirements to ensure consistent heat exchange.
• Exact OEM Fitment: Eliminates the clearance issues and performance drops associated with generic aftermarket blower wheels.

Common Technical Questions

What are the symptoms of a failing Carrier centrifugal wheel?
Technicians usually identify failure through excessive vibration, "thumping" noises during the ramp-up phase, or visible buildup and pitting on the fins that disrupt the factory balance.

How do I confirm the rotation for the LA22LA118?
This wheel is rated for Clockwise (CW) rotation. Always verify the rotation by looking at the hub side or checking the directional arrow stamped on the original housing to ensure proper furnace blower wheel performance.

Does this wheel include the set screw?
Yes, this OEM component typically includes the hardened set screw required to torque the hub onto a 1/2-inch motor shaft.
