Rheia™ Ceiling Diffuser Assembly | Part #10-04-230

The Finishing Touch That Nobody Notices — Exactly As Intended

The Rheia™ Ceiling Diffuser Assembly mounts flush into a finished ceiling and delivers conditioned air smoothly and evenly across the room, with none of the harsh directional draft a stamped metal register creates. In clean white, it reads as part of the ceiling rather than equipment bolted to it.

It connects directly to compatible Rheia™ ceiling boot assemblies, so the termination and the finish work stay part of one coordinated system. Molded from a flame-retardant PC/ABS polymer rated UL94 V-0 and UL 2043 rated for air-handling spaces, and it is 100% recyclable.
