Complimentary to our AXN 12/56 series<br />
(with outlet guide vanes) we supply specially<br />
developed round silencers in 13 sizes.<br />
These units substantially reduce the<br />
sound level.<br />
They are easily fitted on the fan inlet or outlet<br />
side, without any additional intermediateelements.<br />
The silencer housing consists of Sendzimir<br />
galvanized sheet steel.<br />
Mounting nuts are provided internally on<br />
the connecting face sides (hole pattern as<br />
per DIN 24154 – Series 3).<br />
The interspace between the exterior barrel<br />
and the interior sleeve (made of galvanized<br />
perforated sheet metal) as well as<br />
the interior core are filled with a non-combustible<br />
acoustic damping material.<br />
(The sketch shows an axial-flow fan<br />
with extension casing and one round<br />
silencer each on its inlet and outlet<br />
sides).<br />

For higher attenuations several silencers of identical<br />
diameter may be arranged in series.<br />
