Swirl diffuser 250 mm with uninsulated plenum box and side connection
This steel swirl diffuser with fixed vanes, also called a ceiling diffuser, has a 250mm connection diameter, and is supplied with an uninsulated plenum box with 200 mm side connection. Thanks to its high inducing effect, the swirl diffuser is highly suited for efficiently displacing very cool or warm air. The swirl diffuser can be used for both extracting and supplying air.
It is easy to connect a spiral pipe or flexible hose to the side connection on the uninsulated plenum box.
