and use.
Retain this manual for future reference and instruct all
users in the function and usage of the product.
Do not detach factory tted parts as it will hinder the
operation of the lter.
Power cords and pressure hoses must be replaced
immediately if they are damaged. This work must be
carried out by a trained professional.
All electrical connections must be carried out by a
trained electrician.
1.1 Hazard
Dismounting parts of the Dustbox is associated with
danger.
When tting or servicing the Dustbox, it must be
disconnected completely.
1.2 Area of application
The Geovent Dustbox is used for ltering of
contaminated air from industrial processes such as:
welding smoke, grinding and sanding.
The Dustbox CFU-1000 lter is not to be used in areas
which require the use of ATEX certied products.
The Geovent Dustbox CFU-1000 is supplied with a lter
cartridge. (ltration e󰀩ciency: min. 99,90% according to
BIA-test.)
Cleaning of the lter is manual. A shot of pressurized
air is sent through the lter cartridge loosening the par-
ticles attached to the fabric of the cartridge.
It is recommended that the lter shot valve is released
after each use. Press the button on the side of the lter
to release the valve.

2.0 Installation
Geovent Dustbox CFU-1000 must be installed indoors
in a room with plenty supply of fresh air.
Outdoor installation is normally not recommended.
This to avoid condensation issues.
If placed outdoors, place the lter in a dry area where
the temperature is not below -40°C
The Geovent Dustbox CFU-1000 is supplied complete
and ready for installation.
Before installation consider the best placement for the
Dustbox lter.
The following installation should be done by a trained
professional.
Procedure:
1. Geovent Dustbox CFU-1000 is placed on a rm
and level foundation. ( e.g. a concrete oor.)
Allow room for lter change.
2. Geovent Dustbox CFU-1000 is connected to
circular ducts on both dirty and clean side.
(The lower duct connection is always the dirty
side.) Seal the duct connection using tape or rub-
ber seal.
3. To ensure free mixing of air the outlet should be
placed at least to meters over the ridge of the roof
with a wind speed of min. 8 m/s.
Connecting the fan to power:
4. Connection of the Geovent Dustbox CFU-1000
lters electrical components can only be carried
out by a trained electrician.

2.2 Test run - calibration
Before use the function of the lter should be tested.
Also make sure the lter cleaning system works.
Make sure that the entire installation is air tight.
If a whistling sound is heard locate the leak and seal
using exible mastic.
It is recommended that the ventilation unit delivers the
amount of air for which it is dimensioned
Gauge the supplied amount of air using an adjustment
damper. At excess capacity the power consumption
(Amps) can exceed the capacity of the fan motor cau-
sing it to malfunction.
Connection
4.0 Maintenance
The entire extraction installation should be checked at
least once a year by a qualied service technician.
Periodic maintenance:
• All electrical components should be checked yearly.
• Make sure that the air supply for the compressed
air system is clean and dry. Otherwise the lter
cartridges and shot valves can be damaged by
condensation.
• Check the pressure drop of the lter. If the pres-
sure drop exceeds 1800 Pa replace the lter
cartridges.
• Check the clean side of the lter for dust particles
regularly and replace lter cartridges if leaking.
4.1.1 Emptying of collection drawer.
Emptying the collection drawer should be done when
it is two thirds full. Otherwise it could cause damage to
the lter cartridge.
1. The collection drawer is secured with two brackets.
Unscrew the brackets and remove the drawer.
Discard of the contents of the drawer according to
local regulations.
2. Put the drawer back in place and fasten below the
lter.

4.1.2. Replacing lter cartridge.
The lter cartridge should be replaced after 4000-8000
hours of operation or after 4 years.
This is dependent of the load put on the lter.
Procedure:
1. Before dismounting the service hatch on the side
of the lter it is very important that the service tech-
nician is properly protected using safety gear.
2. All power must be disconnected. Make sure that
the power can not be turned on by accident.
3. The compressed air connection should be discon-
nected using the ball valve.
If a ball valve is not tted, shut o󰀨 the compressor
and empty the tank manually using release button.
4. Unscrew all nger screws and remove the service
hatch.
5. The lter cartridge is held in place by three latches
in a ange at the top of the cartridge.
6. Loosen the lter cartridge my simply turning it so
that the latches release.
7. Carefully remove the contaminated lter cartridge
and place it in a large sealed plastic bag.
8. Carefully place the new lter cartridge and secure
it by turning it.
9. Reattach the service hatch and fasten the screws.
(Remember to reconnect power and compressed
air.)
10. Control the lter for function and leaks.
11. Dispose of the contaminated lter cartridge in a
secure manner as prescribed by local authorities.

The cleaning system cannot keep up with the load put
on the lter. Increase the frequency with which you
activate the shot valve.
Shot valve makes a ”snoring” noise.
The ”snoring is caused by foreign objects in the tank.
Trigger the shot valve and the ”snoring” stops.
The pressure drop increases rapidly and the air
ow drops.
The cleaning system cannot keep up with the load put
on the lter. Release the shot valve more often.
