Carrier LA22LA144 Blower Wheel

The Carrier LA22LA144 Blower Wheel is a high-performance HVAC centrifugal fan component engineered for precision air movement in commercial and industrial air handling units. Featuring a 15 1/8-inch diameter and an 11 1/8-inch width, this double-inlet blower wheel is constructed from durable galvanized steel to prevent corrosion and ensure structural integrity under high-static pressure. Designed with a 1 3/16-inch bore and dual set screws on each side, it provides a secure, balanced fit to the motor shaft, minimizing vibration and mechanical wear. As a genuine OEM replacement part, it maintains factory-spec airflow pull and distribution, rated for speeds up to 1600 RPM. The reversible rotation capability offers essential versatility for various housing configurations, making it a critical HVAC air distribution part for maintaining system efficiency. For contractors performing a furnace blower wheel replacement, this unit ensures seamless compatibility with 48PMDM and 50PMBC series units, restoring optimal CFMs while reducing the load on the blower motor.

• Precision Balanced Geometry: Engineered to reduce harmonic vibration, extending the life of motor bearings and the blower assembly.
• Corrosion-Resistant Steel: Heavy-duty galvanized construction withstands the rigorous moisture and temperature fluctuations of commercial HVAC systems.
• Optimized Airflow Efficiency: Forward-curved blade design maximizes air volume displacement at lower decibel levels for quiet operation.
• Universal Shaft Compatibility: The 1 3/16-inch bore with reinforced hubs ensures a slip-free connection to high-torque motors.
