Lau 605599-01 24-Inch 3-Blade Fan – CCW Rotation, ½” Bore, Aluminum Construction, OEM Condenser/Exhaust Fan for HVAC Systems

Condition: Used. Shows visible signs of wear from prior installation. Hub and mounting bore intact.

The Lau 605599-01 is a 24-inch diameter, 3-blade aluminum fan blade engineered for use in HVAC condenser units, ventilation systems, and exhaust assemblies. Manufactured by Lau Industries, this model is designed for counter-clockwise rotation when viewed from the shaft end (CCWSE) and is ideally suited for direct-drive fan motors typically found in residential or commercial condenser and ventilation applications.
The aluminum blades offer a high strength-to-weight ratio and excellent corrosion resistance, especially useful in outdoor or humid environments. A ½-inch bore center hub allows for easy mounting to standard motor shafts. Lau’s factory balancing ensures quiet operation and reduced wear on the motor bearings.
