BSLCU is a circular curved silencer.

Nominal insulation thicknesses are 50 mm or 100 mm. Lack of space is a frequent problem in air treatment installations. This means that it is often difficult to find enough straight lengths to install a straight silencer. This problem can be eliminated by installing a curved silencer. For the same length, it mostly has better attenuation than the equivalent straight silencer. In particular, you get better attenuation at high frequencies 4 and 8 kHz.

Attenuation material is mineral wool. The BSLCU are made of sheet metal and an inner tube made of sheet steel with small openings to be able to withstand mechanical cleaning and at the same time do not interfere with the insertionloss. The space between them is filled with mineral wool and a nonwoven cloth are 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.
