Carrier LA22LA037 Blower Wheel

The Carrier LA22LA037 Blower Wheel is a precision-engineered OEM replacement part designed for high-static pressure applications in Carrier, Bryant, and Payne air handlers and furnaces. Featuring a .625 (5/8 inch) bore diameter, this double-inlet centrifugal fan is balanced to eliminate vibration and prevent premature blower motor bearing wear. Constructed from heavy-duty galvanized steel, the wheel measures 12-1/4 inches in diameter and 10-5/8 inches in width, specifically optimized for high-volume airflow across evaporator coils. The clockwise (CW) rotation and single set-screw hub layout ensure a secure mechanical connection to the direct-drive motor shaft, maintaining consistent CFM delivery even in restrictive ductwork. For service technicians performing a furnace blower repair or upgrading HVAC blower assembly performance, this Factory Authorized Part provides exact dimensional sizing to prevent housing interference and optimize system static pressure.

• Precision Balanced: Factory-set balancing reduces decibel levels and minimizes motor shaft stress.
• OEM Compatibility: Exact replacement for P441-1236 and related 11x10 DD blower components.
• Corrosion Resistance: Galvanized steel construction prevents oxidation in high-humidity air handler environments.
• Standardized Bore: The 5/8" bore with recessed hub allows for rapid installation on standard NEMA frame motors.

• What rotation is required for the Carrier LA22LA037? This wheel is designed for Clockwise (CW) rotation when viewed from the hub end.
• Will this fit a 1/2 inch motor shaft? No, this wheel requires a .625 (5/8") shaft diameter; using a bushing is not recommended for high-RPM blower applications.
• Does this include the set screw? Yes, it features a heavy-duty single set screw for securing the hub to the motor shaft keyway or flat.
