PRICE SCD-FR square cone diffusers are fire-rated Assemblies listed in the UL Listed (Underwriters Laboratories Fire resistance Directory) and ULC Listed (Underwriters Laboratories of Canada Equipment and Materials Directory). This design meets time versus temperature test criteria and NFPA 90A requirements.
SCD-FR square cone diffusers are the most efficient diffuser for any ceiling application. It delivers supply air in a true 360° radial horizontal air pattern onto the ceiling making it ideal for VAV applications. The special contour design of the diffuser cones prevent smudging and streaking associated with many other types of ceiling diffusers.
