Lau g078052486 Blower Pulley 1x7 Inch

Product Description

The LAU g078052486 is a blower pulley designed for use in HVAC air-handling and forced-air systems. With a 1-inch bore and a 7-inch outer diameter, this pulley mounts to the blower shaft and transfers rotational power from the motor via a belt drive. The precision-machined grooves ensure consistent belt tracking and reliable torque transfer. It is compatible with Truflex 3L and 4L belt profiles. Installation is typically performed by HVAC technicians during blower assembly, belt replacement, or drive system upgrades.

This pulley is suited for residential and light commercial forced-air applications where belt-driven blower assemblies are used. Common install scenarios include air handlers, furnace blower sections, and standalone blower cabinets that use V-belt drive configurations. The 7-inch diameter allows for speed ratio tuning when paired with an appropriately sized motor pulley. Single and double groove designs are available within this product family, offering flexibility for both single-belt and dual-belt drive setups.
