If the filter is to be used for filtration of wood dust,
then the filter must be placed outdoors and with a
distance of minimum 2,5 meters from the closest
building.
The explosion hatch is to be placed, so that the
hatch opens into the open, in case of explosion.
The hatch must not be blocked from the outside
and it should be placed so that neighbours and
people passing through is not harmed in case of
explosion.
1.2 Field of application
1.0 General safety precautions
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.
Maintenance, replacement of filter cartridges/
emptying of collection bucket, should only be
done in accordance with guide in section 4.
The GeoFilter GFX can because of the ATEX
approval (explosion hatch etc.) be used for
filtration of aluminium, flavour, wood dust and
other media associated with explosion danger
(zone 20, 21 & 22(D)). The filter can naturally also
be applied from such as welding fumes, where
there is no risk of explosion. Mixing of various
types of process is not recommended since it
might increase the risk of explosion.
Power cables and pneumatic air hoses should be
replaced at once, if they are damaged. This
should only be done by trained electrician and a
HVAC technician.
Do not dismantle any factory-mounted parts,
since it impedes the commissioning of the
equipment.
All electrical installations must be carried out by
an authorised electrician.
1.1 Danger
Explosion danger – because the GFX filter is
ATEX approved, the filter has been designed to
minimize the risk of explosion in the best possible
manner. In order to further minimize the risk of
explosion it is required that the installation, service
and use of the filter must conform with this
instruction manual, why this must be read
carefully before installation and use, since there is
a risk of death or severe personal injury by
explosion.
It is deadly dangerous to dismount any part on the
filter while this is in use.
Always switch off the current when mounting or
doing service on the Filter or when servicing it.
Always run an extra cleaning cycle before the
power is cut.

Instruction manual GeoFilter GFX
The GeoFilter GFB is delivered with filter
cartridges of pleated textile with ALU-coating
(minimum filtration efficiency of 99,90% according
to BIA-test. The filter cartridges are cleaned
automatically by a shock wave send down
through the filter cartridges, whereby the particles
that are caught in the filter fabric will fall off and
land in the collection bucket bellow.
The filter should as a main rule be placed out
doors in order to minimize the damaged in case of
an explosion (When the application is wood dust
the filter must be placed at least 2,5 meter from
the closest building).

2.0 Installation
When the filter is placed out side, there should
always be extracted clean & dry, 20°C hot air
through the filter before use. This operation will
minimize the damaged that can be caused by
frost and humid air.
The filter is delivered complete, fully mounted and
pre-programmed from factory, ready to be
connected to the ducting system and the mains.
Before installing the filter, please make sure that
the optimum installation area is selected. Is there
room enough for the filter indoors? Is there space
enough
for
carrying
out
satisfactory
installation/service of the filter? What about
optimum connection possibilities for piping and
automatics? For outdoor mounting, any noise
nuisances for neighbours should be taken into
account and also ensure that the motor is kept out
of heavy showers and cold weather. It is therefore
recommended to build a small shed around the
filter.

Recommended installation: Place the filter at least
2,5 meters from the building, with the explosion
hatch pointing away from the building. Insure that
random people passing by, can not be injured by
the hatch or explosion pressure.
should always be 2 meter above roof top,
and keep an air velocity above at least 8 m/s.
7.
It is also recommendable to build a protection
roof above (and around) the filter in order to
insure the filter the longest possible life and
minimizes the risk of complications during
operation.
Connection of fan and filter to the mains:
8. Connection of the GFX filters electrical
components should only be done by a
professional electrician.
If indoor installation is the only option, the filter
must be placed so that the explosion hatch has
direct access to the outdoors. Proper precautions,
to insure that people passing by the explosion
hatch is not harmed, must be taken. This can be
done by a fence or proper shielding (visible
signs).
9.
Connect to the main via 220V + PE.
10. For possible combination/ connection
possibilities please see the following
diagrams & separate manual for GFX control
panel.
2.1 Mounting overview
The following installation should only be carried
out by a trained fitter.
Procedure:
1. The GFX filter has to be placed on a solid an
even surface (i.e. a concrete floor). The free
space above the filter has to be minimum
800 mm, to be able to change the filter
cartridges.
2.
The explosion hatch is lead through the wall
and into the open (If installed indoors.)
3.
The GFB filter has to be connected to circular
spiral ventilation duct (SPIRO) on the clean &
dust side (The lower connection side of the
duct is always the dust side). Remember
always to seal the assembly points with
scotch seal and/or duct tape.
4.
In some situations it can be necessary to
install an automatic safety pressure release
valve on the in/outlet side of the filter.
5.
After wards connect 6 Bar clean & dry
compressed air to the top of the filter – is
fasten by means of a pipe plier.
6.
To insure that the extracted air is blended
with the clean air, the duct on the outlet side

Before use, check the functionality of the filter and
adjust the filter cleaning cycle so that it is suits the
current system needs. Make sure that the pause
interval’s for the cleaning system is optimized for
the current air flow – adjust if necessary (see
separate guide for GFB control panel). Check if
there is noticeable shaking or odd noise coming
from the filter when in use.
Make sure that the complete system is air tight. If
whistling noises appears locate the leak and seal
with scotch seal.
It is recommended to check whether the
supplies the correct volume of air, for which
equipment has been dimensioned. I.e. control
volume of air and make sure that it does
exceed the ampere capacity of the motor.

4.1.1 Emptying of collection bucket
When the filter is installed correctly and is ready
for use, there will be no interaction between the
operator and the filter. Obviously the operator
must be aware if there isn’t a correct flow in the
system – in this case, see point 4.0 maintenance.
Emptying of the collection bucket should be done
when it’s about 2/3 full, because more loads could
damage the filter medias.
1.
The collection bucket is removed by
unleashing the quick coupling on the side of
the bucket. Then carefully pull the bucket out
from underneath the filter. The particles in
the bucket shall be destructed in proper
manner by the current regulations.
2.
The bucket is again placed the filter and
strapped on.
4.0 Maintenance
At least once annually, the whole point extraction
plant should be overhauled by an authorised
serviceman.
Periodic maintenance:
• Once a year check all the electrical parts on
the filter.
• Check that the compressed air supply is clean
& dry, so that the filter cartridges and the pulse
valves are not damaged by condensation.
• Check the pressure difference through the filter
and replace filter cartridges if the pressure
drop is above 3.000 Pa.
• Check the clean side (the outlet side) of the
filter with even periods, and change the filter
cartridges if leakage occurs.
At least each 3 month should the filter cartridges
be checked for leaks and flakes. In these cases
shall this be fixed immediately (i.e. replacement of
filter cartridges). Alternatively there can be
mounted an Geovent Airbox on the filter, which
measuret the differential pressure in the filter and
gives alarm if the differential pressure is to high or
low. It can also give a signal to the control panel
to start a cleaning cycle, when a certain
differential pressure level is reached.

4.1.2. Replacement of the filter cartridges
The filter cartridges should be replaced after
approximately 4000-8000 hours of use or max. 4
years. This is naturally determined by the work
load on the filter and dependent on if it’s used for
welding or grinding applications etc.
Procedure:
3. Before the top of the filter is dismounted it is
very important that the service technician is
wearing the correct personal safety
equipment, that meets the requirements of
the current regulations. This could be gloves,
special cloths and respiratory equipment.
4.
All power must be turned off and it should be
made sure that it can not be switch back on
during service.
5.
The compressed air connection shall be
disconnected by means of a ball valve. If no
ball valve is installed, turn off the compressor
and empty the compressed air system for air.
6.
Afterwards the compressed air supply hose
is removed from the filter top by means of a
pipe plier.
weather
Because of the changing weather conditions over
the year, the daily operation of the filter might be
influence by this. I.e. days with heavy rain or frost
it is recommended to inspect the filter visually for
leaks, and that the filter is running a cleaning
cycle, before taking the filter in to use. This
procedure is important in order to insure the
longest possible living time.
When servicing the filter, such as emptying
the collection bucket or replacing the
cartridges, it is ALWAYS required to wear
antistatic outfit and garbage set.

7.
Unscrew all the screws that lock the top to
the filter, with i.e. a 10 mm wrench.
8.
Then remove the top of the filter. Take a firm
grip in the mounted handles and be careful
not to damage the compressed air system on
the inside of the filter top. MAKE SURE NOT
TO DAMAGE THE WIRERING TO THE
PULSE VALVES (is not to be dismounted).
The filter top (the lid) can be placed on the
top of the filter or very close to.
9.
10. Then remove the plate, so that the cartridges
are easy to pull up.
11. The contaminated filter cartridges is carefully
lifted up and placed in a large disposal bag
that is to be sealed properly.
Afterwards remove the 10 mm bolts on the
plate that keeps the filter cartridges to the
filter with a wrench.

12. The new filter cartridge is carefully placed in
the filter (so the media isn’t damaged) and is
fastened with the plate that holds the
cartridges.
4.2 Trouble-shooting
If a situation where problems with increase
pressure drop or low air flow should occur, please
see the following points.
Dust is pushed back and dust is coming back
out through outlets.
The cleaning system has to “push” to much dust
of the cartridges at a time, and the dust is pushed
out into the duct. Chance the pause interval on
the control panel so the time between each
cleaning cycle is lowered until there is no dust
coming out of the outlets (I.e. if the interval is set
at 12 minutes, it can be lowered to 10 minutes. If
this is not enough lower it further).
13. The top of the filter is cautiously placed on
the filter again and tighten with the bolts that
were removed earlier (remember to
reconnect the power and the compressed
air). Give the lit a small push so that it is
placed correctly.
The Pulse valves sounds like they are
”snoring”.
Lower the shooting/pulse time with 0.25 sec. until
the “snoring” sound disappears.
The pressure drop/difference is rising when in
use and the air flow is falling equivalently.
The cleaning cycle can not keep up with the dust
load. Lower the Pause interval until the pressure
drop again is normal. The filter cartridges need to
be changed if this does not work.
14. The used and contaminated filter cartridges
are to be sent to destruction at the local
garbage central.
15. Check the functionality of the filter and for
leaks.
