AUDA/AUDS
The automatic sliding damper AUDA is a com-
pressed air powered damper for tight and rapid
closure.
Because the damper is opened and closed auto-
matically, the extraction is always focused on the
connections, extraction points or machines that
for the time being are in use. This maximizes the
extraction power and reduces the energy con-
sumption. It also creates cleaner end products
and machinery, cleaner floors and a healthier
working environment.
Design
As standard, the damper is made of zinc plated steel, but is also available in stainless steel AISI
304/316.
The pipe connections on the damper are equipped with pull ring edge or straight edge, depending
on the diameter (see table on the next page). The damper can also be delivered with connections
for rolled edge or with flanges.
Air tightness is achieved by using flexible rubber gaskets and sealing rings. Dimensions bigger than
Ø 200 mm, come only with sealing rings.
The standard damper can take a heat with a maximum of +80° C. Sealing rings made of Teflon are
available, in cases when higher temperature is being used. Working preassure is 6-10 bar.
The damper is opened and closed by one or two compressed cylinders, depending on the diameter.
The cylinder i maneuvered by a magnetic port connected to the machinery or to a maneuver switch.
With a micro switch mounted on the damper, the fan can for example be turned on or off when the
damper is opened or closed.
