Glaunach · Vent Silencers
GLAUNACH type DAA combined diffuser / absorber silencer
Integrated combination of a type DA diffuser silencer with one or more type A absorber stages, for 50 dB and more. Covers almost any noise reduction requirement.
Where a single principle is not enough, the DAA stacks both: the diffuser stage removes the jet noise at the source and the absorber stages take out what remains across the spectrum. This is the silencer for the strictest limits, for example vents near residential areas or plants with night-time noise restrictions.
