SLKNU is an extract air terminal device consisting of a silencer and conical inlet with wire guard.

Nominal insulation thicknesses are 50 mm or 100 mm.

Attenuation material is mineral wool. The SLKNU's are made of strong outer spiral seemed tube and an inner tube made of sheet steel with small openings to be able to withstand mechanical cleaning and at the same time not interfere with the insertion loss. The space between them is filled with mineral wool and a nonwoven cloth is inserted between inner tube and the attenuation material, to prevent fibres from the insulation getting into the duct system. SLKNU can be cleaned by rotating nylon brushes, vacuum cleaner or damp cloth.
