Lau 01333703 Blower Wheel
The Lau 01333703 Blower Wheel, model DD9-8A, is a high-performance direct drive blower wheel engineered for consistent airflow in residential and commercial furnaces, air handlers, and condensers. Featuring a 9 1/2-inch diameter and 8-inch width, this unit is constructed from galvanized cold-rolled steel for superior corrosion resistance and structural integrity under high static pressure. The 1/2-inch bore hub is secured via the Preslok center disc design, which ensures positive blade retention and precise balance at speeds up to 1750 Max RPM. With a CCW rotation (viewed from the hub end) and convex center disc, this double inlet blower wheel provides quiet, vibration-free operation for demanding HVACR duty cycles. As a universal replacement blower wheel, it serves as a critical component for technicians aiming to restore OEM-level CFM performance in HVAC systems.
Key Benefits- Preslok Technology: Incorporates a mechanical lock at the center disc to prevent blade shifting and ensure long-term mechanical stability.
- Quiet Performance: The 43 forward curved blades are precisely spaced to maximize airflow while minimizing acoustic resonance.
- Corrosion Resistance: Fabricated from galvanized steel to withstand moisture-heavy environments typical of evaporator and condenser sections.
- High Velocity Integrity: Balances efficiency and durability, rated for direct drive motor applications up to 1750 RPM.
Is this wheel compatible with CW rotation motors?
No, this specific model is designed for CCW rotation (Counter-Clockwise) when viewing the bore/hub end. Installing on a CW motor will result in significant CFM loss and potential motor overheating.
What is the temperature rating for this blower wheel?
While the galvanized steel is rated for higher temperatures, it is typically recommended for HVACR applications where air temperatures do not exceed 135°F (60°C) to protect the associated drive motor.
Does this fit a 5/8" motor shaft?
No, this wheel features a precision-machined 1/2-inch bore. Ensure your motor shaft diameter matches exactly to avoid runout or mounting failure.
