1.0 General safety precautions
IMPORTANT – Please study all the instructions before
mounting and commissioning.
Please keep these instructions in a safe place and in-
struct all users in the function and operation of the pro-
duct.
Exchange of filter/maintenance should only be imple-
mented after studying section 4 thoroughly.
Avoid the dismantling of any factory-mounted parts, sin-
ce it impedes the commissioning of the equipment.
All electrical installations must be carried out by an
authorised electrician.
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 gas spring and the carry-
ing arm could involve a risk of mutilation.
Boring in the gas spring or other ways of puncturing it is
deadly dangerous.
1.2 Field of application
The GEOVENT ASA-3 Arm is the ideal Extraction Arm
for the extraction of welding smoke, grinding dust, fu-
mes, etc., where the well-being of the operator is in
focus with regard to lightness, ergonomics and efficien-
cy of the Arm.
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.
The hose may be damaged and leaky via outer loads,
e.g. by a screw driver. Avoid such load in order to safe-
guard a long life.
1.3 Handling
Always use gloves when handling. During transportati-
on all lifting must be in the arm. Note that it is possible
to pinch your fingers between the gas spring and arm.
When the arm is monuntet, it may only be handled by
the hood

2.0 Installation
The ASA-3 Arm is supplied partly assembled. Depen-
ding on model, it may consist of 1 partly assembled car-
rying arm, 1 funnel and 1 set of hose with clamp. The
centre part of the carrying arm is to be turned around
and fastened with two 13 mm fixed spanners.
Before mounting the Arm, please make sure that the op-
timum 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 ac-
cordance with the table below:
Recommended installation height ASA-3 Arm:
2 m 2500 mm
3 m 2500 mm
4 m (incl. 1 m extension arm) 2500 mm
5,5 m (incl. 2.5 m extension arm) 2500 mm
7 m (Incl. 4 m extension arm) 2500 mm
8 m (Incl. 4 m extension arm) 2500 mm
1.5 Construction
Wall bracket: Steel bracket, powder enamelled yellow
in RAL 1007. The rotary joints can rotate 180°.
Funnel: Light-weight aluminium funnel ø80, 100, 125,
160 or 200 mm. The ø160 and the ø200 mm funnels are
supplied with integrated handle. The funnel is powder
enamelled in RAL 1007. May be rotated in all possible
positions.
Arms and friction joint: 25 x 25 mm aluminium pipe,
connected via knee joints with friction discs and disc

Procedure:
1. The wall bracket is firmly attached to the wall by me-
ans of 4 off 10 mm bolts. (When using the extension
arm, please fix this bracket first – refer to item 2.1)
2. Mount the Arm on the wall bracket with the M16 bolt
and friction discs. Make sure to fasten it in such way
that the Arm is easily rotated. If the inner joint/arm
hasn’t the wanted friction, the bell washer can be
loosen or tighten, or by adjusting the spring retainer
(against the wall to tighten – away from the wall to
loosen).
3. Mount the centre part by taking the supplied M12 bolt
through 3 disc springs, the alu half, the friction disc,
the other alu half and 3 disc springs and fasten them
with an M12 lock nut. Tighten the joint so that the
arm is easy to rotate, however, still so much that it is
self-retentive in a lightly bent position.

4. Mount the funnel on the outer joint by taking the sup-
plied M8 bolt through 3 disc springs, the alu half, the
friction disc, the other alu half and the 3 disc springs
and fasten them with an M8 lock nut.
5. The hose is mounted on the funnel by tightening the
clamp around the funnel and the hose. Now pull out
the hose to max. so that the least possible resistance
is left in the hose and fasten with the enclosed plastic
binders. Subsequently, the hose is mounted on the
branch pipe by means of the clamp.

The aluminum pipes are mounted on the pipe-holders
with the supplied self-tapping screws. The shortest of
the pipes are mounted on the outer arm. Then mount
the hose pieces for the bends. The rubber band is put
on the outside of the pipe/funnel, then pull the hose over
the pipe and secure it with clamps. When the hose is
attached, the rubber band is pulled over the clamp.
2.1 Mounting of optional equipment
Mounting of extension arm
Start by fixing the extension arm to the wall, as described
in item 2.0 (applies to 1.0 and 2.0 m extension arms).
For the 2.5 and 4.0 m extension arms, please fix the wall
bracket first. (Refer to the hole dimensions).

At 4 meters, every joint is assembled and then the Arm
is mounted. Next, the spiro pipe is fastened to the exten-
sion arm by means of the enclosed self-cutting screws.
The part between the spiro pipes is assembled by me-
ans of clamps and the supplied hose.
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. The connection is made by exten-
ding the power cord, which is attached inside the Arm
and it is to be fixed on the Arm. Next, the power cord is
connected to the transformer (24V 220V) 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 documentati-
on for the actual product.
The electrical installation is to be carried out by a certi-
fied electrician.
2.3 Trial run – exact adjustment
After the final mounting, the ASA-3 Arm should be adju-
sted to the typical working area, for optimum utilisation
of the Arm. Do so by adjusting the rotary joints mentio-
ned in item 2 by means of 2 off 17 mm fixed spanners.
3.0 User instruction – application
For normal use, the Arm is to be self-retentive in the
required position within the working area. The bracket of
the Arm supplies a 180° 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 par-
ticles will be caught.

Less optimal welding situation.
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. In-
stead, please move the Arm to the required position
and wait a moment until the friction discs have locked
the Arm. If this does not work, please tighten the loo-
se joint with two 17 mm fixed spanners.
• 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 (please refer to item 2).
• Please check the condition of the hose, the spring
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.
5.0 Liability
Warranty
Geovent A/S grants a warranty for products, which are
defective, when it can be proved that the defects are due
