Fields of application
The dimensions of the overflow box have been adjusted to the requirements of dry construction and can easily be integrated into partition walls. The integrated telephony sound absorber has the same duty as the previously separate inserted telephonie sound absorber in the duct system, for which rarely enough space was available. The transmission of telephone cross-talk through the wall is thus effectively prevented.
The overflow box with the integrated cross-talk sound attenuator is made of galvanised sheet steel and an inner lining of special sound absorbing plates, which are laid out in a reverse labyrinth. To give the overflow box an elegant finish, a cover frame is included which can be fitted to the box by means of a clamp mounting device. This will also cover up any gap that may exist between the wall and the diffuser.
