Vents SR 125/600 ventilation silencer is designed to absorb noise. In a galvanized steel casing, the internal space is filled with non-flammable sound-absorbing material. For connection with other elements of the ventilation system, connecting flanges with a rubber seal are provided. This model is designed for connection to air ducts or other round elements with a diameter of 125 mm. The length of the silencer is 600 mm.
Installation
The silencer is attached to the air ducts using clamps. It is recommended to install a silencer where the air ducts (supply and exhaust) pass through the wall of the room in which the ventilation equipment is located. In this case, the silencer must have its end 'include' into the wall. You can also achieve maximum noise absorption by installing two noise suppressors - before the ventilation unit (fan) and after.
