Steel silencer TOS 250 UNIWERSAL156

In order to reduce the noise of the fan transporting to the ventilation duct and further to the ventilated rooms, duct silencers with an internal through or flow core were constructed. The structure of the outer jacket is made of polyester-glass laminates made in the same technology as the fan housings, permanently colored with pigment in the technological process of their production. The sound insulation material was selected as optimal as possible to the noise of the fan, taking into account the full spectrum of its acoustic power.
