Lau 00851912 Blower Wheel
The Lau 00851912 Blower Wheel, also identified as Model A9-9A, is a high-performance replacement blower wheel engineered for demanding belt-drive HVACR applications. This double inlet centrifugal fan features a 9.5-inch diameter and 9.5-inch width, providing the necessary static pressure for consistent airflow in commercial and residential air handling units. Constructed with galvanized steel and utilizing a Preslok wheel design, the blades are mechanically attached to the center disc via two hubs for maximum structural integrity. The 3/4-inch bore hub includes a single set screw and a 3/16 x 3/32 keyway to ensure a secure, slip-free connection to the motor shaft. With a 2400 max RPM rating, this industrial blower wheel is balanced for dual rotation (CW/CCW), offering versatile compatibility across various blower housing configurations. Its forward-curved blade geometry is specifically designed to minimize vibration and noise, making it a reliable choice for furnace blower wheel maintenance and high-static ventilation tasks.
Key Benefits
- Universal Compatibility: The Model A9-9A design with dual rotation capability allows this 9.5 x 9.5 blower wheel to replace numerous OEM parts in both clockwise and counter-clockwise systems.
- Durable Construction: Heavy-duty galvanized steel blades and Preslok mechanical locking provide superior resistance to torque and corrosion.
- High-Speed Performance: Rated for up to 2400 RPM, making it suitable for high-velocity belt drive blower assemblies.
- Precision Fit: Features a standard 3/4" bore with a integrated 3/16" x 3/32" keyway for professional-grade mechanical power transmission.
Common Questions
How do I confirm if this Lau wheel replaces my existing squirrel cage? Check your current wheel for the Lau 00851912 or A9-9A stamp. Measure the diameter and width (both 9-1/2") and verify your motor shaft is 3/4" with a keyway. Can this blower wheel be used in direct drive motors? No, this specific model is a belt drive blower wheel designed for use with pulleys and belts. Direct drive wheels typically require a different hub configuration. Does rotation direction matter when installing the A9-9A? This double inlet wheel is designed for CW/CCW rotation, meaning it can be installed in housings requiring either lead-edge direction, provided the hub and set screw are positioned correctly on the shaft.This item is not eligible for free shipping.
