The strengths of INDUSILENT


Low pressure losses reduced energy expenditure in the central unit.


INDUSILENT is a ventilation element for large creative freedom in the form of a slim 20 mm joint or with an attractive decorative cover. The installation can be designed to be almost invisible through the use of specific architectural elements.


High sound attenuation value. Building material class A2 according to DIN 4102 (incombustible). No connection to the duct network required.


INDUSILENT enables free transfer of air from room to room. The acoustic weakening of the partition wall as a result of the transfer grille installation is minimised owing to the highly effective integrated inner lining. Taking account of a maximum pressure difference of 20 Pa, specific air flow rates of up to 200 m³/hm are possible.

Installation length 500, 800, 1000, 1200 mm special lengths on request
Box length 200 mm (Typ T) / 300 mm (Typ S)
Air flow rates bis 200 m³/hm
Pressure loss < 20 Pa
Wall thickness from 58 mm (Tpy TS)
Building material class according to DIN 4102 A2 (incombustible)

Installation situation

The transfer grille is installed between the board layers during construction of the drywall. Once the drywall construction and plastering works are finished, the dust protection must be removed from the air slots. In the case of type TR/SR, a decorative frame is fitted on both sides.
