Installation
The silencer may be installed, vertically, horizontally
or in any position close to the end of the piping.
Design
The operating of the silencer is based on the absorp-
tion system. The Gasflow passes straight-through a
perforated tube, surrounded by highly effecient sound
absorbing material, thus giving an excellent attenuation
over a wide frequency range.
The silencer is delivered without insulation and
fastening fittings.
Pressure Loss
The pressure loss will not be more then in a straight
tube having the same lenght and bore as the silencer.
