Lau 01333401 Blower Wheel
When you are maintaining direct drive blower assemblies, the Lau 01333401 Blower Wheel (Model DD9-4A) is a standard-setting replacement for ensuring quiet, stable airflow. This double inlet blower wheel features a 9.5-inch diameter and 4.5-inch width, specifically engineered for high-static pressure environments. Built with galvanized steel construction, the 43 forward-curved blades are locked into a convex center disc using the Preslok technique, which ensures positive blade retention even at the 1750 Max RPM rating. The 1/2-inch bore facilitates a secure fit on standard motor shafts for CW rotation as viewed from the hub end. As a veteran-preferred HVAC blower wheel replacement, it minimizes vibration and mechanical stress on the motor, extending the system's operational life. Whether you are servicing a residential furnace or a light commercial unit, this direct drive blower wheel provides the precise alignment needed for efficient air distribution and low-decibel performance.
Key Benefits:- Preslok Blade Retention: High-integrity mechanical locking of the blades into the center disc prevents detachment at high speeds.
- Corrosion Resistance: The cold-rolled galvanized steel finish protects against moisture and oxidation in damp plenum environments.
- Dynamic Balance: Precision-engineered to reduce harmonic vibration, protecting the motor bearings and ensuring quiet operation.
- Universal Replacement: Designed as a drop-in Lau DD9-4A equivalent for a wide range of furnace and air handler brands.
- How do I determine the rotation? This wheel is CW rotation when viewed from the hub (bore) end. Always verify your motor's lead orientation before installation.
- Will this fit a 5/8-inch shaft? No, this model is bored for a 1/2-inch shaft. For different bore sizes, a different part number or a shaft reducer (if applicable) would be required.
- Is this suitable for high-heat applications? This wheel is recommended for standard HVAC application temperatures and is rated for performance up to 1750 RPM in typical conditions.
