Round silencer diameter 125 mm - length 900 mm with 50 mm insulation

The rigid round silencer for spiral pipe has a connection diameter of 125 mm and a length of 900 mm. The silencer is provided with 50 mm insulation. The thickness of the insulation (50 mm) consists of mineral wool. An intermediate layer prevents pieces of wool from ending up in the duct system.

The round silencer reduces the noise of your ventilation system to a pleasant level and is suitable for connection to a round spiral pipe. The fixed outer jacket and perforated, sound insulating inner casing are made of Sendzimir galvanised steel. To achieve maximum results, it is important that the diameter of the silencer is equal to the diameter of your duct. Does your ventilation system make a lot of noise? The longer the silencer, the more sound reduction.

The silencer is fitted with a safe rubber seal as standard.

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