Lau 01332203 Blower Wheel

Replacing a worn or vibrating blower wheel is critical for maintaining system static pressure and motor longevity. The Lau 01332203 Blower Wheel is a direct drive, high-performance component engineered for heavy-duty HVACR applications. This 10 5/8" diameter x 10 5/8" wide wheel features a double inlet design with a convex center disc, providing the structural rigidity needed for 1750 Max RPM operations. Constructed from galvanized steel, this forward-curved blower wheel ensures quiet airflow and consistent alignment. The 1/2" bore hub is designed for a precision fit on standard motor shafts, and the clockwise (CW) rotation must be verified against your existing assembly to ensure proper air discharge. Whether you are servicing a furnace, fan coil, or air handler, using a Lau DD10-10A replacement ensures your HVAC blower motor operates at peak efficiency without the turbulence associated with lower-quality aftermarket impellers. Focus on the Preslok center disc technology for a secure, slip-free mechanical attachment to the motor shaft.

• Precision Balanced: Factory-set balance reduces vibration, extending the life of your blower motor bearings.
• High-Speed Rating: Rated for up to 1750 RPM, making it compatible with various multi-speed direct drive motors.
• Durable Construction: Made with corrosion-resistant galvanized steel for long-term reliability in high-humidity environments.
• Optimized Airflow: The double inlet design maximizes CFM delivery while maintaining low decibel levels.

• How do I confirm the rotation of my old wheel? To determine CW rotation, look at the wheel from the hub/motor side; the blades must rotate clockwise to move air correctly.
• Can I use a 1/2" bore wheel on a 5/8" shaft? No, the bore size must match the motor shaft exactly. This model is strictly for 1/2 inch shafts.
• What does a convex disc mean for installation? A convex disc curves outward toward the motor, which affects how the wheel sits on the shaft. Always measure your offset before tightening the setscrew.
