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).
Insulation thickness 100 mm.
Tested according to ISO 7235.
