York S1-026-25529-704 Blower Wheel

The York S1-026-25529-704 is a heavy-duty 15" x 15" centrifugal blower wheel designed for high-static pressure applications in commercial and residential air handlers. Featuring a 1-inch bore and Counter-Clockwise (CCW) rotation (viewed from the drive end), this double-inlet blower wheel is engineered for precise balance and optimal airflow delivery. Constructed with galvanized steel blades to resist corrosion and structural fatigue, it serves as a critical OEM replacement part for ensuring consistent CFM output and reducing motor strain. When performing a changeout, verify the hub configuration and set screw alignment to prevent vibration-induced failure. This HVAC blower wheel is built to handle the rigorous duty cycles typical of York and Guardian systems, providing the mechanical reliability required for maintaining system static pressure and overall thermal efficiency in large-scale furnace and AC configurations.

• Precision Balancing: Factory-aligned to minimize vibration and extend the lifespan of the blower motor bearings.
• Enhanced Airflow Efficiency: Optimized blade pitch ensures maximum CFM delivery across high-resistance ductwork.
• Industrial Construction: Rugged galvanized steel design provides durability in high-moisture or variable temperature environments.
• Direct Fit Compatibility: Specifically engineered as a drop-in York replacement part to reduce field modification time.

What is the correct way to determine rotation for this wheel?
Rotation is determined by viewing the wheel from the hub side or drive end; this S1-026-25529-704 is a CCW rotation unit.

Will this wheel fit a 3/4-inch motor shaft?
No, this unit features a 1-inch bore. Attempting to use a reducer bushing is not recommended for high-torque HVAC applications.

How do I ensure the new blower wheel is balanced after installation?
Always ensure the set screws are tightened onto the flat of the motor shaft and check for any lateral runout before restoring power to the assembly.
