Lau 01333602 Blower Wheel

The Lau 01333602 is a high-performance DD9-7A blower wheel engineered for residential and light commercial direct drive air handling applications. This 9 1/2" diameter x 7 1/8" wide wheel features 43 forward-curved blades and a convex center disc construction for superior structural integrity at high velocities. Built from galvanized steel, this double inlet centrifugal wheel is designed for CW rotation (clockwise viewing the hub end) and is rated for a 1750 Max RPM. The 1/2" bore includes a precision-machined hub with a set screw for secure shaft mounting, ensuring consistent balance and reduced vibration in high-static environments. As a professional-grade HVAC blower wheel replacement, the 01333602 serves as the primary 667149 direct replacement for Nordyne and other major OEM equipment, maintaining factory-spec airflow and static pressure performance.

• OEM Compatibility: Seamlessly replaces Nordyne 667149 and 667149R in furnace and air handler assemblies.
• Preslok Technology: Features a center disc mechanically attached to each blade for positive retention and heavy-duty reliability.
• Precision Balance: Dynamically balanced to eliminate harmonic resonance and minimize bearing wear on the blower motor.
• Corrosion Resistance: Cold-rolled galvanized steel construction withstands high-humidity conditions common in evaporator coil cabinets.

What is the correct rotation for the Lau 01333602?
This wheel is designed for clockwise (CW) rotation. Technicians should verify rotation by viewing the wheel from the hub/bore end to ensure correct airflow direction.

Will this wheel replace a 9.5 x 7 squirrel cage in a direct drive system?
Yes, the Model DD9-7A is the industry standard for these dimensions, provided the motor shaft is 1/2" and the application requires a double inlet configuration.

Can this be used in high-heat furnace applications?
Yes, the galvanized steel construction and temperature rating of up to 200°F make it suitable for standard gas furnace and electric heat air handlers.
