Lau 00840310 Blower Wheel
The Lau 00840310 Blower Wheel is a high-performance A12-12A model engineered for belt drive applications within light commercial and residential HVACR systems. This double inlet blower wheel features a 12-5/8" diameter and 12-5/8" width, utilizing Preslok center disc construction where the center disc is mechanically attached to each blade for superior structural integrity at high velocities. With a 5/8" bore, a single set screw, and a standard 3/16" x 3/32" keyway, it ensures a secure fit on the motor shaft even under its 1800 Max RPM rating. Its CW/CCW rotation capability makes it a versatile HVAC blower wheel replacement for various air handlers and furnace configurations. This galvanized steel centrifugal blower wheel is balanced to minimize vibration, maintaining efficient airflow across the coils while reducing mechanical stress on bearings. When performing a blower motor repair, verifying the 12-5/8 inch outer diameter and hub dimensions is critical for maintaining OEM performance standards in central air conditioning units.
- Universal Preslok Design: Features interlocking blades and a center disc for rugged durability in heavy-duty air handling units.
- High-Velocity Performance: Rated for up to 1800 RPM, providing consistent CFM delivery for large-scale ventilation needs.
- Corrosion Resistance: Constructed from galvanized steel to prevent oxidation and extend the service life in high-humidity environments.
- Flexible Configuration: Supports dual rotation (Clockwise and Counter-Clockwise) to fit numerous manufacturer specifications.
Common Questions
What is the best way to determine the rotation of a Lau A12-12A?
For this double inlet model, rotation is determined by viewing the wheel from the hub/bore end. This specific 00840310 part is engineered to support both rotations, making it a reliable choice for field replacements where original specs may be unclear.
Will this wheel fit a 1/2" or 3/4" shaft?
No, this unit is specifically machined with a 5/8 inch bore. Always measure the motor or blower shaft with a caliper to ensure compatibility, as using a different bore size will prevent proper installation and drive alignment.
Why is a belt drive wheel preferred over direct drive in larger systems?
Belt drive blower wheels allow for precise speed adjustments via pulley ratios, enabling technicians to fine-tune system static pressure and airflow more effectively than most fixed-speed direct drive setups.
