Description
The Lennox 88K34 TRI-Power V-Belt 71″ Outer Circumference BX68 is designed for power transmission and used for rooftop units, air handlers, and blower assemblies in HVAC systems. It transfers rotational force between motor and pulley components to support fan and compressor operation during heating and cooling cycles. It allows adjustment around smaller pulleys while maintaining stable belt tracking and consistent torque transfer. It operates as part of the mechanical control system that supports air flow movement and overall system performance.
