Round silencers
SIL

Description

The silencers are delivered with the SPIRAL® system seals in the standard version. The diameter sizes d1 > 315 mm require ordering the NSL male couplings which need to be installed in the silencer before connecting the silencer to the ductwork. The male fittings are available separately. They are not delivered with the silencers. Glass wool thickness inside the silencer: 50 mm for SIL-50 – depends on the outer cladding size. 100 mm for SIL-100 – depends on the outer cladding size.
Insulation:
Insulation material: glass wool.
Insulation type: trimmed from reel, flexible.
Reaction to fire: A1 acc. to EN 13162
