Flexible rectangular silencer
Flexible rectangular silencer is a rectangular plate construction. The silencers can have any position in the system. The range of operating temperatures is from-30 to + 50. The recommended maximum speed of the air passing through the silencer is 8 m/C.
The silencers are made from galvanized steel (quality class is not lower than dx510 by en10327). Nonflammable mineral wool board covered with a black glass-cloth is used by way of noise absorbing material. The glass-cloth prevents blowing fibers from mineral wool into the ventilation channels. The connecting pipes provide a rack rail connection with ducts of rectangular cross-section.
