The 150mm Metal Non-Return Damper controls airflow in circular ducting and stops air from flowing back into the system. It is built with a galvanised steel collar and lightweight aluminium blades, spring-loaded so the blades close positively as soon as airflow stops. The one-way design keeps outside air, odours and contaminants out of the duct run. Suitable for bathroom exhaust, kitchen rangehood and ducted heating and cooling systems, it mounts vertically or horizontally and is used in both residential and commercial installations.
