The flexible non-woven silencer has a connection diameter of 100 mm, a length of 1000 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.

Tips How can I reduce the noise of my ventilation system?

It is important to know where noise in your ventilation system is coming from, before you can reduce it. A ventilation system causes air to be moved and in doing so, vibrations are released. To do this, a mechanical ventilation system is equipped with a motor that also creates vibrations. Many of these vibrations produce noise and thus annoyance. The noise level can vary from one ventilation system to another.
