LFAB is designed to attenuate fan noise and air noise from e.g. dampers. The baffles are supplied with assembly profiles and are ideal for use in large, site-built silencers, in shafts or for supplementing in existing ducts. LFAB conforms to all requirements according to the current building regulations in terms of cleanability, fibre safety, emissions and microorganisms.
LFAB can be manufactured in a number of variants, the reported data is only a sample. 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 silencers are installed independent of the air direction. In the event of large sizes or restricted entry openings, the baffles are delivered in sections that are easily assembled on site.
