Variant with spigot has a groove for a lip seal, suitable for circular connecting ducts to EN 1506 or EN 13180
Insertion loss measured according to ISO 7235
Casing air leakage to EN 15727, class D
Optional equipment and accessories
Socket-type spigots on both ends
Raised edges at both ends
With lip seals on both ends
Circular silencer Type CS
Circular silencer Type CS
Application
Circular silencers Type CS for the reduction of air-regenerated noise in the circular ducts of air
conditioning systems
