Lennox 85L53 Wheel

The Lennox 85L53 blower wheel is a heavy-duty, 15" x 15" centrifugal fan wheel engineered for high-performance air handling in commercial and industrial HVACR systems. This OEM replacement wheel features a 1 7/16" bore diameter and is constructed from durable tacked steel, providing the structural integrity required for precise dynamic balance and vibration-free operation. Specifically designed for belt drive blower assemblies, it replaces Lennox 85L5301 and legacy part numbers including LB-29333BCS and 78L7801. With a clockwise (CW) rotation and 51 individual blades, this component is frequently found in Lennox KCC and KHA series rooftop units, including KCC240S4-01 and KHA180S4-1. Technicians should verify hub end rotation and set screw alignment during installation to maintain optimal CFM delivery and motor longevity. This robust part ensures exact mechanical fit for Allied, Armstrong, and Ducane equipment sharing this Lennox 85L5301 cross-reference profile.
