SRS is a conventional design with overall dimensions that do not exceed the duct connection dimensions. The attenuator is manufactured in standard duct sizes as detailed in the table below.
Rectangular straight attenuator from the SRS series. SRS is the attenuator is manufactured with a casing of galvanized sheet steel and stone wool absorption material covered by a plastic inter-liner and wire mesh to prevent the migration of fibers into the airstream and to protect the acoustic media from grease and oil in kitchen applications.
The SRS is available with splitter widths 100 mm.
