The HART COOLEY 850 10 04 brn is a 2-way floor diffuser designed to distribute conditioned air in residential and light commercial HVAC systems. Measuring 4 inches by 10 inches, this floor-mount diffuser fits standard floor openings and directs airflow in two directions for balanced room coverage. The brown finish blends with common flooring materials, making it a practical choice for installations where aesthetics matter alongside function. HVAC technicians and installers use this diffuser as part of forced-air supply systems connected to central heating and cooling equipment.
This diffuser is suited for residential forced-air HVAC installations where a floor-mounted supply outlet is required. The 4-inch by 10-inch opening size accommodates standard ductwork terminations in wood or concrete subfloor applications. The 2-way airflow pattern makes it appropriate for rooms where airflow needs to be split across two directions rather than concentrated in one. It is typically installed during new construction or as a direct replacement in existing floor duct systems.
Designed as an OEM-style replacement or new-construction floor diffuser for residential and light commercial forced-air HVAC supply systems using standard 4-inch by 10-inch floor duct openings.
Installation is typically performed by a licensed HVAC technician or qualified installer. Shut off the air handling unit or furnace before removing an existing diffuser or cutting a new floor opening. Ensure the duct collar dimensions match the 4-inch by 10-inch nominal size before securing the diffuser to the floor. Follow local mechanical codes for supply air outlet placement and clearance requirements.
