Circular sound attenuator in galvanized steel with insulation shell thickness between 50 and 100 mm
Composition
Circular silencers are designed with an external galvanised duct
system
Inner casing is made of perforated sheet steel
Cavity is filled with soundabsorbent mineral wool
Mounting
The attenuators should be mounted using duct suspension
clamps, around the duct connection Ød The outside diameter
ØD of these attenuators may have small deviations in size
