LFAR

Silencer LFAR is designed for good cleanability with removable baffles and accessibility for cleaning the duct system. It is intended for installations with high cleaning requirements, e.g. kitchen flues, healthcare, clean rooms, etc. LFAR complies with all requirements as per applicable building regulations in terms of cleanability, fibre safety, emissions, and microorganisms.

LFAR is manufactured in three attenuation classes (type 1, 3, and 5), where type 1 has the best attenuation. The inlet and outlet sides of the baffles are equipped with angled profiles to limit the pressure drop. The absorption material has a type-approved surface layer that is cleanable and fibre-proof. The casing is co-insulated with the duct system. The silencer is installed irrespective of the air direction. As standard it comes with slip-clamp connections, but can also be supplied with flange connections. In the event of large sizes or restricted entry openings, the silencers are delivered in sections that are assembled on site.
