Duct Silencer Kanal-GKD for Effective Noise Reduction in HVAC Systems

The silencer body and the plate body are made of galvanised steel. The plates are filled with noise-absorbing mineral wool with a protective coating to prevent the fibres from blowing out. The standard length of the sound attenuator housing for all sizes is 950 mm.

On request, silencers can be made in other lengths. Channel-GKD are mainly installed between fans and main ducts. In exhaust mechanical ventilation systems, silencers are used both to protect against noise in the rooms served and to reduce the noise coming from the fans to the outside.

Silencers can be installed independently of spatial orientation and remain functional. The advantage of this silencer is that there is no need to install a straight section of duct in front of the silencer to equalise air velocity across the duct cross-section. Multiple silencers can be used for additional noise reduction...
