The ZSR rectangular sound attenuator is
used for reducing the noise level in civil
and industrial air conditioning systems. It
consists of a shell made of galvanized she-
et, containing sound attenuators.
The shell thickness is 0.7 to 1.2 mm, de-
pending on size; the flanges have fixing ho-
les, on the corners.
Sound absorbent parting walls consist of a
frame made of galvanized sheet-iron, containing mineral wool
panels covered with a white or black anti-erosion glass fabric,
like interglass, with a high coefficient of sound absorption.
The ZSR model can be equipped with an additional protection
(on sound attenuators) made of perforated sheet. In this case
the sound attenuator denomination is ZSR K.
