The HART COOLEY 470 18 wht is an 18-inch perimeter sunburst diffuser designed for ceiling or wall air distribution in commercial and residential HVAC systems. This diffuser delivers a radial, sunburst pattern of airflow around its perimeter, promoting even air distribution across the space. Constructed from metal, it is built to handle the demands of professional HVAC installations. The white finish suits standard interior applications. HVAC technicians and mechanical contractors install this diffuser as part of supply-air distribution systems where a wide, perimeter-pattern throw is required.
This diffuser is suited for use in light commercial and residential installations where perimeter-pattern air distribution is specified. It fits into standard supply air duct openings and is appropriate for ceiling applications requiring a sunburst-style diffuser. The 18-inch size accommodates moderate to larger duct openings in typical forced-air systems. It is commonly specified on mechanical drawings wherever perimeter diffusion is called for in office, retail, or residential spaces.
Designed as an OEM-style replacement or new-installation diffuser for residential and light commercial forced-air supply systems requiring an 18-inch perimeter sunburst diffuser.
Installation should be performed by a licensed HVAC technician or mechanical contractor. Shut down the air handling unit and confirm the supply air is off before beginning installation. Secure the diffuser to the duct collar or ceiling grid per the manufacturer guidelines and local mechanical codes. Do not restrict the perimeter openings during installation, as this will impair airflow distribution.
