The new FRS-SDB silencer box is the latest addition to our tried-and-tested flexpipe ^plus air distribution system, which offers flexible and uncomplicated solution for the installation of KWL systems with heat recovery in single family homes and apartment buildings.

The new FRS silencer box is the ideal companion for the ceiling-integrated FRS-VE distribution element. Together, remarkable sound insulation properties of 30 dB can be achieved. In most applications, separate unit silencers can therefore be completely eliminated.

The compact silencing box is mounted directly to the distribution element, reducing the space requirement to a minimum. There are two installation options to choose from horizontally on the ceiling or vertically on the wall. Thanks to additional connection pieces, it can also be used as a straight distributor. This enables intelligent and space-saving air distribution over several floors.

The robust metal construction offers a simple, quick to install and therefore cost-saving silencing solution. The generously dimensioned inspection opening ensures effortless accessibility for subsequent cleaning work.
