SLGU is a circular straight silencer
Nominal insulation thicknesses are 100 mm or 150 mm.
Attenuation material is mineral wool. The SLGU are made of strong outer spiral seemed tube and an inner tube made of 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.
Technical data for insertion loss, pressure drop and self-generated noise based on test conducted in accordance with ISO 7235.
