RS PRO Steel Air Diffusion Valve Diffusion Valve 100 mm

Complete your ceiling air supply installation with these air diffusers. Our air diffusion valves are compatible with rigid or flexible ducting, easy to install and are constructed from two component parts that include a diffuser and spigot mount plate.

First create a hole in the ceiling with the appropriate diameter, insert the mounting plate and secure it with screws, and insert the diffuser rotating clockwise until it locks in place. To adjust the airflow rotate the valve and the air will escape at a 90° angle passing along the ceiling or wall.
