1.0 General safety precautions
IMPORTANT - Please study all the instructions
before installing and commissioning the lter.
Please keep manual for future reference.
Instruct all users in the function and operation of the
product.
Maintenance, replacement of lter cartridges should
only be done in accordance with section 4 in this
manual.
Power cables and pneumatic air hoses should be repla-
ced at once, if they are damaged. This should only be
done by trained electrician and ventilation tter.
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
It is dangerous to dismantle the lter while in operation.
When installing or servicing of the lter make sure that
the power is disconnected.
1.2 Field of application
GeoFilter GFO-XT is used for ltration of oil saturated air
or fumes from polluting industrial processes such as ma-
chining, cutting and metal working involving cutting oil.
The GeoFilter GFO-XT comes with lter cartridges of
di󰀨erent pleated textiles with or without coating
(minimum ltration e󰀩ciency of 99,90% according to
BIA-test - see section 1.3.)

Temperature surroundings -10°C - +65°C
Relative humidity must be below <90%
The pressure drop in the lter will vary depending on
the load and how dirty the lter cartridges are. The lter
cartridges must be replaced, when the pressure drop
exceeds 1.200 Pa.

2.0 Installation
To avoid condensation problems the lter should be
installed inside. However, if this is not possible, it can
be placed under a protection roof and the surrounding
temperature does go below minus 12°C. make sure to
use clean and dry air.
Consider the optimum installation area before
installation. Is placement of the lter inside possible?
Is there enough room for installation and service of
GFO-XT lter? Is there optimal connectivity for piping?
Make sure that there is su󰀩cient ground clearance, so
you can disconnect GFO-XT lter lid when replacing
the lter cartridge. At the bottom of GFO-XT lter there
must be room for the lter to drain the oil from the
mounted tank drain tap.
Procedure:
1. GFO-XT lter is inserted in the vertical duct system
or console
2. GeoFilter GFO XT is to be connected to a circular
spiral ventilation duct (SPIRO) on both clean and dirty
side. (The lower pipe connection is always dirty side).
Remember to seal the connection with joint compound
and/or tape!
3. To ensure the free ow of air, the return should be
two meters above the ridge of the roof with an air
velocity rate of at least 8 m/s.
2.2 Test Run - adjusting
We recommend you ensure the ventilation system sup-
plies the air ow, the system is dimensioned for.
Measure the airow and adjust using adjustment dam-
per. In case of overcapacity the power consumption
(amps) may exceed the capacity of the motor of the fan
which may cause the motor to overheat and eventually
fail.
3.0 User instruction
When the lter has been mounted and properly instal-
led, ready to use, there will be no interaction between
user and lter. Of course, the user must be aware of is
the correct ow in the system.
After max 8 hours of operation followed by min. 8 hours
rest.
4.0 Maintenance
A qualied technician should inspect the entire exhaust
ventilation system - at least once a year.
Periodic maintenance:
• Check pressure drop across lter and replace
lter cartridges, if this exceeds 1.200 Pa.
• Check the lter’s clean side of oil periodically and
replace lter cartridges in case of leaks.
• Empty the lter reservoir of oil using the drain
tap at the bottom.
4.1. Replacing lter cartridges
1. It is important that the service technician is
wearing the appropriate personal safety
precautions as prescribed by the Danish Working
Environment Authority. This must be in place before
removing the top of the lter.
2. Loosen the bolts holding the lid in place.
3. Lift the lidtop of to gain access to the top plate in
which the lter cartridge is mounted.
4. Loosen the plate holding the lter cartridges in
place and remove the cartridges.
5. Place the contaminated lter cartridges in a plastic
bag,which is sealed and disposed of according to
local regulations for disposal of oil and chemical
waste.
6. Install the new lter cartridge on the top plate
and secure it with the top plate and close lid.

4.2 Trouble shooting
Problem: The lter does not absorb oil from saturated,
polluted air, as it is supposed to.
Possible solution:
Check if the lter cartridge is correctly oriented. Filter
cartridge opening should be facing up.
Problem: Insu󰀩cient airow.
Possible solution:
Check if replacement of the lter cartridge
needs replacement.
Replace the lter cartridge, if that is the case.
Problem: Noise from the lter.
Possible solution:
Check if the lter cartridge is properly
secured to the top plate. Secure the lter
cartridge.
Problem: Oil in the lter reservoir does not bleed.
Possible solution:
Check if grinding dust or metal shavings blocks the
drain tap.
Clean, if this is the case.
