Lau 01333501 Blower Wheel
The Lau 01333501 Blower Wheel is a precision-engineered DD9-6A replacement designed for direct drive blower motor applications in residential and light commercial HVAC systems. This double inlet centrifugal wheel features a 9 1/2-inch diameter and a 6-inch width, optimized for consistent airflow delivery and static pressure performance. Built with a 1/2-inch bore and convex center disc design, it ensures structural integrity at speeds up to its 1750 Max RPM rating. This Lau replacement wheel utilizes CW rotation (Clockwise as viewed from the bore side) and is finished in galvanized steel for corrosion resistance in high-cycle environments. For contractors handling furnace blower repairs or air handler maintenance, the 01333501 provides an exact mechanical match to OEM specifications, ensuring proper balance and minimal vibration. Integrating this galvanized blower wheel into your assembly restores system efficiency and mitigates HVAC blower motor strain caused by imbalanced or damaged blades.
Technical Specifications & Performance Benefits
- Direct Drive Compatibility: Designed specifically for direct drive blower motor configurations, eliminating the need for pulleys or belts.
- High-Speed Rating: Engineered to maintain mechanical stability at a 1750 RPM max speed.
- Convex Hub Configuration: The convex center disc provides superior torque distribution across the 1/2" shaft interface.
- Optimized Airflow: The double inlet blower design maximizes CFM output while maintaining a compact physical footprint.
- Galvanized Construction: Resists moisture and environmental wear, essential for long-term HVAC air handler operation.
Common Installation Questions
How do I determine the correct rotation for this blower wheel?
Rotation is determined by looking at the hub/bore side. The Lau 01333501 is a CW rotation blower wheel. Ensure your motor matches this orientation to prevent airflow reversal or motor overheating.
Can I use this wheel if my motor has a 5/8" shaft?
No, this model features a 1/2-inch bore. Forcing a fit or using an adapter is not recommended as it compromises the balance and safety of the centrifugal fan assembly.
What are the symptoms of a failing DD9-6A blower wheel?
Excessive vibration, "thumping" noises during the startup cycle, or reduced airflow across the heat exchanger often indicate a warped or fouled blower wheel blade.
