circular straight silencer.
Nominal insulation thicknesses are 50 mm or 100 mm.
Attenuation
material is mineral wool. The SLU'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. Silencer can be cleaned by rotating nylon brushes,
vacuum cleaner or damp cloth.
Tested according to ISO 7235 standard.
Special materials, sizes and flanges on request. Please contact Lindab sales.
