Lau Blower Wheel 12 5/8D 9 1369325

The Lau 1369325 is a 12-5/8 inch diameter by approximately 9-1/2 inch wide blower wheel for larger direct-drive centrifugal blower assemblies in light commercial and large residential air handling equipment.

At 12-5/8 inches this is a substantially larger wheel than the residential norm, used in equipment where higher airflow and greater static pressure capability are required. The larger diameter develops more pressure at a given rotational speed, which allows the blower to serve longer duct runs and higher-resistance systems without resorting to higher shaft speed and the noise that accompanies it.

Larger wheels carry more rotating mass, which makes balance and hub security correspondingly more important. A large wheel running with a loose hub imposes significant cyclic load on the motor bearings and will fail the motor rapidly.

Confirm diameter, width, bore diameter, hub position, and rotation direction before ordering, and verify that the motor is rated for the load. Fitting a larger wheel than the original to an existing motor increases airflow and motor current and is a common cause of nuisance thermal overload trips.

Check clearance around the full circumference and rotate by hand before energising.
