LRCFU is a straight silencer with circular connections and low overall height.

LRCFU has a compact height making it particularly suitable for installation above suspended ceilings or where space is otherwise limited. Fulfils tightness class C.

Attenuation material is mineral wool. The LRCFU are made of strong rectangular outer casing with circular connections. The insulation inside the silencer are covered with a cloth to be able to withstand mechanical cleaning and at the same time does not interfere with the insertion loss. The cloth is also there to prevent fibres from the insulation getting into the duct system. Silencer can be cleaned by rotating nylon brushes, vacuum cleaner or damp cloth.

Technical data for insertion loss, pressure drop and self-generated noise based on test conducted in accordance with ISO 7235.
