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 oors 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 anges.
Air tightness is achieved by using exible 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 Teon 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.

Installation and maintenance
Installation
When positioning the damper, the risk of personal injury must be taken into account. The damper
must therefoe be installed outside the working zone, e.g. at least 2,1 meter above the oor level.
As standard, the pipe connections are equipped with clamp rims. Installation can be carried out in
an optional position, but we recommend horizontal.
Connecting pipe work is to be suspended in such a way that the damper is not subjected to rupturing
forces. These can cause the damper to jam och to get stuck.
Electrical installation
Before starting the electrical installation the damper must be connected to the duct work, otherwise
the connections on the damper should be covered securely. Electrical connection must be carried out
by a qualied electrician.
Before starting up
1. Check that the damper blade runs smoothly. This should be done after the mechanical installation.
2. Check that the damper is opened and closed when intended.
Regular maintenance
The damper is maintenance free. When required, it can be cleaned using a cloth dipped in ethylated
spirits.
Troubleshooting when the damper blade jams or gets stuck
1. The damper needs to be cleaned
2. There are rupturing forces in the pipe system
3. The damper blade is damaged
4. Loose sealings
Service switches or lockable master switches for fans must be turned
off when working with the damper.
Declaration of conformity according to EU Directive 2006/42/EC.
Be aware that the unit may not go into service until the machine or the system it is to be included
in, complies with the requirements of the EU machinery directive.
