Trane WHL2557 Blower Wheel

The Trane WHL2557 Blower Wheel is a precision-engineered OEM replacement part designed for high-performance centrifugal fan applications in Trane and American Standard air handlers and furnaces. This 11-10DD blower wheel features a counterclockwise (CCW) rotation and a 1/2 inch bore size, making it a drop-in solution for maintaining static pressure and design cfm in residential and light commercial systems. Constructed with 53 concave blades and a double-discharge (DD) configuration, the WHL02557 is factory-balanced to eliminate vibration-induced noise and mechanical wear on the motor bearings. For technicians troubleshooting restricted airflow or rattling in the cabinet, this 11.75-inch diameter blower wheel ensures the assembly meets original efficiency ratings and thermal management requirements. Its heavy-duty galvanized steel construction provides the structural integrity needed for high-speed operation and consistent directional airflow across the heat exchanger or evaporator coil.

• OEM Compatibility: Exact replacement for Trane WHL2557 and WHL02557, ensuring housing clearances and shaft alignment are maintained without field modification.
• Optimal Airflow Delivery: The 53-blade design is engineered to restore factory-specified air volume and velocity in multi-speed or variable-speed systems.
• Reduced Mechanical Stress: Precision balancing limits run-out, preventing premature failure of the blower motor and reducing ambient decibel levels.
• Durable Technical Design: Features a robust 1/2" bore hub and reinforced blades capable of enduring the startup torque of high-efficiency motors.

What is the exact rotation and bore of the WHL2557?
This wheel is specifically designed for counterclockwise (CCW) rotation—determined by viewing the wheel from the hub/bore side—and fits a standard 1/2-inch motor shaft.

Will this wheel resolve vibration issues in a Trane furnace?
Yes, because the WHL2557 is a balanced OEM blower wheel, it is the direct solution for replacing warped, dirty, or damaged wheels that cause harmonic resonance and cabinet rattling.

Is this a Double Discharge (DD) or Single Inlet wheel?
This is an 11-10 DD (Double Discharge) wheel, meaning it pulls air from both sides to maximize airflow efficiency within the blower housing.
