The Carrier LA22LA105 Blower Wheel is a high-duty OEM replacement centrifugal fan designed for specific Carrier and Bryant commercial and industrial air handling units. Measuring 13.19 inches in diameter with a 9.5-inch width and a precision-ground 1.187-inch bore, this steel blower wheel ensures stable airflow delivery in high-static pressure applications. As a factory authorized part, it is balanced to minimize vibration, preventing premature bearing failure in the blower motor and maintaining the structural integrity of the housing. This component is commonly utilized in models like the Carrier 50DD 016 600, 39LF06, and 39LB06. For technicians performing HVAC blower wheel replacement, verifying the bore size and rotation is critical to ensure proper torque transfer from the motor shaft. This industrial-grade metal wheel is engineered to support up to 2500 RPM, making it a reliable choice for maintaining HVAC system efficiency and consistent air circulation in rooftop units and large-scale split systems.
