Lau 01333201 Blower Wheel

The Lau 01333201 Blower Wheel is a high-performance direct drive blower wheel engineered for reliable service in residential and light commercial HVAC applications. As a model DD9-9A, this double inlet blower wheel features a 9-1/2 inch diameter and 9-1/2 inch width, specifically designed to maximize airflow while maintaining a compact footprint. Constructed from galvanized cold-rolled steel, the wheel utilizes 43 blades and a Preslok center disc for superior stability and reduced vibration during high-speed operation. This CW rotation blower wheel is rated for a 1750 max RPM, ensuring effective static pressure performance across 1/2 inch bore motor shafts. It serves as the direct replacement for R02592A002, offering a precise fit for technicians performing maintenance on older air handlers and furnaces. The concave center disc design facilitates efficient air distribution into the centrifugal housing, while the 135°F temperature limit provides safe operation within standard heating and cooling cycles.

Key Benefits

• Optimized Airflow: The double inlet configuration increases air intake volume for improved system efficiency.
• Industrial Durability: Galvanized steel construction protects against corrosion and extends the component life in high-humidity environments.
• Vibration Control: The Preslok center disc ensures the hub remains securely locked to the 1/2 inch bore, preventing mechanical slip.
• Precision Balance: Each wheel is factory-balanced to eliminate noise and reduce wear on the blower motor bearings.

Common Questions

How do I confirm the rotation of this wheel?
The Lau 01333201 is a CW rotation wheel. Rotation is determined by looking at the hub/bore end of the wheel.

Can this wheel be used in heating-only applications?
Yes, but ensure the operating environment does not exceed the 135°F limit typically dictated by the blower motor's thermal protections.

Is this compatible with 5/8 inch motor shafts?
No, this specific model features a 1/2 inch bore. Always verify the motor shaft diameter before installation to ensure a proper fit.
