The HART COOLEY 800 10 04 brn is a two-way floor diffuser designed for residential and light commercial forced-air HVAC distribution systems. Finished in brown, this shallow-profile unit measures 4 inches by 10 inches and sits flush with floor surfaces to direct conditioned air in two opposing directions. The shallow depth makes it suitable for installations where floor cavity clearance is limited. Licensed HVAC technicians and sheet metal contractors typically specify this diffuser for supply-air floor registers in ducted heating and cooling systems.
This diffuser is intended for floor-mounted supply air applications in ducted HVAC systems. The 4-inch by 10-inch opening fits standard duct boot sizes commonly found in residential construction. The brown finish blends with wood and laminate flooring common in living areas, hallways, and bedrooms. Its two-way deflection pattern allows airflow to be directed along the floor plane, improving comfort distribution in occupied spaces.
Designed as an OEM-style replacement or new-installation floor diffuser for standard 4-inch by 10-inch supply air duct boot openings in residential and light commercial forced-air HVAC systems.
Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling system before removing or replacing a floor register. Ensure the duct boot opening matches the 4-inch by 10-inch neck size before installation. Secure the diffuser flush to the finished floor surface to prevent air bypass around the frame.
