Rheia™ Flush Mount Ceiling Diffuser Assembly

Clean, Omnidirectional Air Distribution — Flush to Your Ceiling

Upgrade your home's air distribution with our premium 360-Degree Flush Mount Ceiling Diffuser Assembly. Engineered as a snap-and-twist termination piece for micro-duct home-run ventilation systems, this unit delivers beautiful, even air blending across any room with minimal pressure drop. Say goodbye to bulky, traditional metal registers — this architectural round profile sits completely flush to the drywall for a clean, modern aesthetic that disappears into your ceiling.

Designed for tool-free installation, the diffuser faceplate twists cleanly into the ceiling boot with an integrated latching system that pulls it tight against the drywall — no tools, no fuss, no visible hardware.
