The flexible non-woven silencer has a connection diameter of 250 mm, a length of 500 mm and has finished ends (cuffs) on both sides. This makes the silencer easy to connect to, for example, a spiral pipe or fan. The connections on both sides have a pipe diameter and are therefore fittings. The inner hose of the flexible silencer consists of non-woven polypropylene. In addition, the flexible silencer has an aluminium laminate outer jacket.
