The HART COOLEY 1500 10 wht is a white metal drop-in ceiling diffuser designed for use in HVAC supply air distribution systems. Measuring 24 inches by 24 inches, it is sized to fit standard lay-in ceiling grid openings and accepts a 10 inch round collar for ductwork connection. The drop-in design allows the diffuser to seat directly into a T-bar ceiling grid without additional fasteners in most installations. This type of diffuser is typically installed by HVAC technicians during new construction or retrofit projects where balanced air distribution across a room is required.
This diffuser is suited for residential and light commercial HVAC applications where a 24 inch by 24 inch ceiling tile grid is in use. The 10 inch collar connection is compatible with standard round duct branches at that diameter. Its white finish blends with most standard ceiling tile systems. HVAC contractors and mechanical installers commonly specify this diffuser for conference rooms, offices, retail spaces, and residential great rooms where flush ceiling aesthetics and reliable airflow are both priorities.
Designed as an OEM-style replacement or new-installation diffuser for standard 24 inch by 24 inch T-bar lay-in ceiling grid systems with 10 inch round duct collar connections.
Installation is typically performed by a licensed HVAC technician or mechanical contractor. Before installation, shut off the air handling unit or furnace serving the duct branch to prevent uncontrolled airflow during fitting. Confirm the ceiling grid opening and collar duct diameter match the diffuser specifications before seating the unit. Follow local mechanical codes and ASHRAE guidelines for diffuser placement and throw distance to ensure proper room air distribution.
