Lau Fan Blade 22" Clockwise 27-Degree 3-Wing

The Lau 60557301 is a 22 inch clockwise rotation, 27 degree pitch, three-wing propeller fan blade for condenser fan applications in larger HVAC equipment.

Twenty two inch blades serve four and five ton residential condensing units and light commercial equipment, where the condenser coil area requires substantial airflow.

Larger blades carry more rotating mass, and that mass has two consequences. It increases the starting load on the motor, which is one reason larger condenser fan motors are more sensitive to a degraded run capacitor: the capacitor's contribution to starting torque matters more when there is more inertia to accelerate. And it magnifies the effect of any imbalance, since the cyclic load at the bearings scales with the mass involved.

Both point to the same practical conclusion. On larger fan assemblies, blade condition and capacitor condition are worth verifying together, and a blade that shows damage should be replaced rather than straightened.

Confirm diameter, rotation, pitch angle, wing count, hub bore, and hub depth before ordering, and check that the assembly runs true and that running current matches nameplate after installation.
