Lau 01333603 Blower Wheel
The Lau 01333603 Blower Wheel is a precision-engineered double inlet centrifugal fan designed for high-performance air handling in residential and light commercial HVAC systems. This Direct Drive Blower Wheel, model DD9-7A, features a 9.5-inch diameter and a 7.125-inch width, making it a standard replacement for many OEM HVAC blower assemblies. Constructed with a 1/2-inch bore and a convex center disc, it is engineered for Counter-Clockwise (CCW) rotation as viewed from the motor side. The Lau DD9-7A is rated for a maximum speed of 1750 RPM, ensuring efficient airflow and static pressure management in various furnace and air handler configurations. Its galvanized steel construction provides the structural integrity required to prevent blade deformation under high-velocity conditions. For technicians performing a furnace blower wheel replacement, this component ensures proper dynamic balance to minimize vibration and extend the service life of the blower motor bearings.
Key Benefits
- Optimized Airflow: The double inlet design maximizes air intake volume for improved heat exchange efficiency.
- Precision Balance: Individually balanced blades reduce mechanical stress on the 1/2 inch bore motor shaft and prevent resonance.
- Direct Drive Compatibility: Designed for seamless integration with direct drive blower motors, simplifying field installation.
- Industrial Durability: The convex hub design provides superior structural support for the fan blades at 1750 RPM.
Common Questions
How do I verify the rotation for this blower wheel?
This wheel is rated for CCW rotation. Always determine rotation by looking at the wheel from the hub/motor side to ensure compatibility with your existing housing.
What are the exact dimensions for the Lau 01333603?
The unit measures 9-1/2 inches in diameter and 7-1/8 inches in width. Using a 9.5 x 7.125 blower fan that matches these specs is critical for maintaining correct static pressure.
Can this wheel be used in belt-drive applications?
No, this is a direct drive fan wheel specifically designed to be mounted directly onto the motor shaft of a compatible HVAC blower motor.
