Use:

• noise reduction in ventilation and air-conditioning and vent ducts.

Design:

The external cover is made of galvanised sheet steel. The connection frames are made of DW duct sections and H-corners. As a result, the silencer has sufficient rigidity and can be easily integrated into the duct system. The frames of the silencer noise insulation panels are made of galvanised sheet steel and are filled with sound-absorbing material - mineral wool. The glass fibre fabric that covers the outer side of the noise insulation panels tightly prevents the wool from penetrating into the duct system. The use of high-quality damping materials and the proper installation of the product guarantee high damping parameters.

Standard dimensions:

• height B: 300, 450, 600 and 900 mm;
• length L: 600, 1000 and 1250 mm.

The silencers are acoustically tested acc. to ISO 7235.
