IMPORTANT – Please study all the instructions
before mounting and commissioning.
Please keep these instructions in a safe place and
instruct all users in the function and operation of
the product.
Do not dismantle any factory-mounted parts,
since it impedes the commissioning of the
equipment.
An authorised electrician must carry out all
electrical installations.
1.1 Danger
Explosive media – The Extraction Arm is not
suitable for the extraction of aluminium dust, flour,
textile dust nor for sawdust or other media, which
are connected with danger of explosion, without
specific approval from Geovent A/S.
Placing the hand between the spring and the
carrying arm could involve a risk of mutilation.
Demounting the spring is deadly dangerous.
1.2 Field of application
The GEOVENT Compact Arm is the ideal
Extraction Arm for the extraction of welding
smoke, grinding dust, fumes, etc. when there is
only limited space available in the working area.
Since the Arm is telescopic, it only requires
minimum space, and still it is a perfect
combination between the large arms with major
suction capacity and the smaller arms, which are
easy to position.
The Extraction Arm is not suitable for the
extraction of aluminium dust, flour, textile dust nor
sawdust or other media, which are connected with
danger of explosion, without specific approval
from Geovent A/S.
Under no circumstances may the balancer, which
is mounted on the ceiling bracket, be loosened or
tightened to the extent that the inner spring
breaks. Therefore, be careful in order to avoid
loading the spring in the outer areas.
The hose may be damaged and leaky via outer
loads, e.g. by a screwdriver. Avoid such load in
order to safeguard a long life.

Instruction Manual COMPACT Arm
Arms and friction joints: The Arm consists of three
joints. The inner carrying arm is executed in
45x45 mm aluminium profile, supplied with
adjustable fittings, where the power of the spring
may be adjusted. Inside this profile, the middle
35x35 mm ALU-profile is moved by means of
journal bearings. The outer joint, a 25x25 mm
aluminium profile, is moved by means of journal
bearings in the middle profile.
2.0 Installation
The COMPACT Arm is supplied partly assembled.
Depending on model, it may consist of one
carrying arm, one funnel, and one set of hose with
clamp and rubber band. As standard, the Arm is
prepared for ceiling mounting, however, in most
cases it will be mounted on a wall by means of a
wall bracket (to be ordered separately).
Before mounting the Arm, please make sure that
the optimum working area is selected. Is there
space enough for the satisfactory utilisation of the
Arm? What about connection possibilities for
piping and automatics? The optimum installation
height is then to be selected in accordance with
the table below:
Recommended installation height COMPACT Arm:
1-2 m 1800 mm
1.5-3 m 2000 mm
3.0 to 7.0 m (incl. extension arm) 2500 mm
Procedure:
1. For wall mounting, attach the wall bracket
firmly to the wall by means of 4 off 10 mm
bolts (when using the extension arm, please
fix this bracket first – refer to item 2.1).
2. Then the ceiling bracket is mounted, either in
the ceiling or in the wall bracket (refer to the
drawing below). The bracket is fixed via
attaching the 4 off 8 mm bolts with 4 off
bevel-edged washers and lock nuts.
3. Then the Arm looks like the one shown on
the picture below. The functionality of the
Arm is tested and the inner joint is tightened
up, if necessary.
4. The outer joint for the funnel is tested and
tightened up, if necessary. The funnel must
be self-retaining in all positions.

5. Subsequently, the hose is mounted on the
ceiling bracket. The rubber band is taken out
over the ceiling bracket, after which the hose
is fixed by means of a clamp. Bending the
edge of the hose is the best way of doing
this, so that the steel spiral is pulled/twisted
up on the bracket. When the hose has been
properly fixed, the rubber band is finally
pulled over the clamp.
6. The hose is mounted on the funnel by
tightening the clamp around the funnel and
the hose. (NB. Remember first to pull the
rubber band over the funnel). When the hose
has been fixed properly, the rubber band is
pulled over the clamp. Subsequently, the
Arm is connected to the complete piping
system.
7. If the telescopic function cannot remain in the
required position or if there is too much
resistance in the Arm, please adjust the
balancer at the back of the ceiling bracket.
2.1 Mounting of optional equipment
Mounting of the extension arm
Start by fixing the extension arm to a solid wall,
e.g. a concrete wall (applies to 1.0, 2.5 and 4.0
m). (Please refer to the whole dimensions).
At 4 meters, every joint is assembled and then the
Arm is mounted. Next, the spiro pipe is fastened
to the extension arm by means of the enclosed
self-cutting screws. The part between the spiro
pipes is assembled by means of clamps and the
supplied hose. Subsequently, the Arm is attached
to the extension arm.
Mounting of the damper
Is factory-mounted. Contact your dealer.
Mounting of light
The mounting of light and net should have been
taken care of by the factory. Extending the power
cord, which is attached inside the Arm, where it is
to be fixed, makes the connection. Next, the
power cord is connected to the transformer (24V
Æ220V), which again is connected to the mains.
Light specifications:
Type: Halogen
Power: 50 W 60°
Voltage: 12 V
Recommended Trafo-power: 70 W
2.2 Power connection
For connection of various electrical components
(e.g. light sensor), please refer to the enclosed
documentation for the actual product.
The electrical installation is to be carried out by a
certified electrician.
2.3 Trial run – exact adjustment
After the final mounting, the COMPACT Arm
should be adjusted to the typical working area, for
optimum utilisation of the Arm. Do so by adjusting
the points mentioned in item 2 (3. 4. and 7.)
exactly.
3.0 User instruction – application
For normal use, the Arm is to be self-retaining in
the required position within the working area. The
bracket of the Arm supplies a 360° rotary working
area.
If the equipment has been correctly dimensioned,
the funnel of the Arm should be placed in vertical
position 300-500 mm over the blanks to be
welded. That is just above the pollutant. Thus up
to 99% of the polluting particles will be caught.
Less optimal welding situation.
2.5 & 4 m Extension arm1 m Extension arm

Instruction Manual COMPACT Arm
Always check that the correct volume of air is
extracted by the suction head/funnel.
The Arm does not work if …
- unauthorised parts have been mounted on the
Arm (e.g. power point on the funnel)
- the Arm is pushed towards the required
position. Instead, please move the Arm to the
required position and wait a moment until the
friction discs have locked the Arm.
- something has been hung on the extension
arm. It is only meant to be capable of carrying
the weight of the actual Arm.
4.0 Maintenance
Periodic maintenance
•When it becomes difficult to position the Arm,
e.g. if it will not remain in the required position,
please adjust the movable joints or the
balancer (please refer to item 2).
•Please check the condition of the hose, the
spring, the balancer as well as the friction
discs, and exchange them if necessary. Please
contact your dealer in respect of spare parts.
At least once annually, the whole point extraction
plant should be overhauled by an authorised
serviceman.
