Circular silencers TAR
TAR silencers are designed for attenuating the noise transferred by circular ducts in ventilation systems. They are usually located between fans and intake or extraction ducts as well as before intake ventilators which supply air to rooms requiring high acoustic comfort.
An external silencer housing is made of zinc-plated sheet. Inside the housing, there is an attenuating insert, made of nonflammable sound absorbing material, protected by a shutter made of perforated zinc-plated sheet. TARs are normally fitted with nipple connectors adjusted to the standardized diameters of circular spiro ducts. It is possible to order customized silencers with sleeve or flange connectors.
