Product Description

The LAU g078052544 is a belt-drive blower pulley designed for use in HVAC air handling equipment. With a 3/4 inch bore and a 9 inch diameter, this pulley fits standard blower shaft configurations found in residential and light commercial forced-air systems. Precision machined grooves ensure accurate belt tracking and reduced slippage during operation. The g078052544 is compatible with Truflex 3L and 4L belt profiles and is available in single and double groove configurations. HVAC technicians and mechanical contractors install this component during blower assembly, drive train replacement, or system retrofits where belt-drive blower wheels are in use.

This pulley is suited for belt-drive blower assemblies in ducted HVAC systems including gas furnaces, air handlers, and packaged rooftop units that use fractional or standard V-belt drive configurations. It is a direct fit for applications requiring a 3/4 inch bore and a 9 inch outer diameter pulley matched to Truflex 3L or 4L belts. Technicians selecting this component should verify bore size, groove count, and belt profile against the existing drive system before installation.
