Lau 00840301 Blower Wheel
The Lau 00840301 Blower Wheel, specifically the Model A12-12A, is a heavy-duty double inlet centrifugal fan wheel engineered for high-demand belt drive blower wheel replacement applications. This 12-5/8 inch blower wheel features a precision-balanced galvanized steel construction with 43 blades, utilizing Lau’s Preslok technology where two hubs and a center disc are mechanically attached to each blade for maximum structural integrity. With a 12-5/8 inch width and a 3/4 inch bore, it is designed for secure mounting via a 3/16 x 3/32 keyway and a single set screw. This unit is fully reversible, supporting both CW/CCW rotation, and is rated for a 1800 Max RPM, making it suitable for a wide range of commercial air handlers and ventilation systems requiring consistent static pressure. When air volume and vibration control are critical, this industrial-grade wheel ensures the mechanical stability required to protect your motor bearings and belts under constant load.
- Universal Application: Reversible rotation (CW/CCW) allows this one part number to cover multiple equipment configurations.
- Superior Balance: Preslok center-disc design reduces harmonic vibration, extending the life of the blower assembly.
- Resilient Construction: Corrosion-resistant galvanized steel blades maintain their pitch and alignment at speeds up to 1800 RPM.
- High Torque Transfer: Standard 3/16" x 3/32" keyway ensures a positive mechanical connection to 3/4" motor shafts.
Common Questions
Will a 12-5/8 x 12-5/8 blower wheel fit my HVAC unit?
Compatibility depends on the internal clearance of your blower housing and the motor shaft size. This model requires a 3/4" shaft and at least 13 inches of clearance for the 12-5/8" diameter and width.
What is the max RPM for Lau A12-12A?
This specific wheel is engineered for performance up to a maximum of 1800 RPM. Exceeding this limit can cause blade deformation or balance failure.
How do I replace a double inlet blower wheel?
Ensure the power is disconnected, remove the belt, and loosen the set screw. Slide the old wheel off the 3/4" shaft, align the keyway of the new Lau 00840301, and tighten the set screw firmly against the 3/16" key.
