The HART COOLEY 150 08 wht is an 8-inch round ceiling diffuser designed for supply air distribution in residential and light commercial HVAC systems. Finished in white, it mounts flush to standard ceiling surfaces and disperses conditioned air in a radial pattern to promote even room coverage. HVAC technicians and sheet metal contractors install this diffuser as part of ducted forced-air systems where a clean, round outlet profile is required. The white finish suits standard drywall and drop-ceiling installations where aesthetics matter alongside airflow performance.
This diffuser is suited for residential forced-air systems and light commercial ducted applications. It connects to an 8-inch round duct collar and is typically installed in living spaces, offices, hotel rooms, and similar occupied areas where uniform air distribution is the primary goal. The round profile integrates with standard round-to-ceiling boot fittings and can be installed in both new construction and retrofit projects.
Designed as an OEM-style replacement or new-installation ceiling diffuser for 8-inch round ducted residential and light commercial forced-air HVAC systems.
Installation is performed by a licensed HVAC technician or sheet metal contractor. Shut down the air handling unit and confirm the supply duct is de-pressurized before removing or installing the diffuser. Secure the diffuser to the ceiling boot or duct collar per local mechanical code requirements. Do not restrict the diffuser neck with insulation or fasteners that reduce the effective open area.
