Silencer LFIK is intended for the attenuation of fan noise in ventilation ducts. LFIK adresses good practice with respect to cleanability, fibre-proofing, emissions and microorganisms.

LFIK 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 provided with angled profiles to limit the pressure drop. The absorption material has a type approved surface layer which is cleanable and fibre-proof. LFIK can where necessary be fitted with an inspection panel (must be clearly stated when ordering). The silencer can be installed irrespective of the direction of the air flow. It is delivered as standard with spigot connection but can also be provided with flange connection (must be clearly stated when ordering). For larger sizes or restricted transport openings the silencer can be delivered in sections for site assembly.
