Beschrijving

e DC 1800/2800 EX is an electrically operated, robustly
constructed dust extractor for use in conjunction with dust-
generating operations in industry. Dust extractors of Type
22 are suitable for the collection of ammable dust in Zone
22. Industrial dust extractors are intended to be used for the
suction and removal of dust deposits. Explosion protection
is provided by the insulation of the electrical parts and the
potential equalisation of the components that come into
contact with dust. De machine kan worden gebruikt voor
de inlaat temperaturen tussen +10 en +40 graden Celsius.
e DC 1800/2800 EX is suitable for general cleaning
operations. Regular cleaning of the workplace is important
to prevent dust explosions.
e machine operates with negative pressure. Separation of
the coarse particles takes place in a cyclone, and separation
of the ne dust takes place in the lter unit.
e material is separated into a container that is attached di-
rectly to the cyclone. e lter is cleaned using reverse pulse.
e material that has been vacuumed up and ltered is col-
lected in a container with a capacity of 20 litres with a plastic
sack insert (part no. 42384H).

thus easily disposed of. Carefully remove the full sack from

Always check that the electrical equipment and potential
equalisation cables are undamaged, and that all acces-
sories are antistatic. Connect to a power source outside
the zone in accordance with the voltage speci ed on the
rating plate of the machine.
Het lter zal bij normaal gebruik over het algemeen één à
twee keer per dag moeten worden schoongemaakt or, if the
machine is equipped with a pressure gauge and the needle
is in the red zone.
To clean the lter:
1. Start the machine.
2. Disconnect the hose from the suction casing.
3. Close the suction hose tightly, e.g. by pressing it
against the oor. Closing the hose produces maxi-
mum negative pressure in the machine.
4. Open the door on the side 3 to 6 times.

This Standard covers the safety of dust extractors
with electric motors, including dust separators and
back-pack vacuums, used for wet extraction, dry
extraction, or wet-and-dry extraction, supplied
for commercial use indoors and for outdoor use
with and without accessories, in order to collect com-
bustible dust in an atmosphere (Zone 22) designated
as explosive.
CAUTION! This machine contains hazardous dust.
Emptying and any maintenance operations, includ-
ing the removal of dust collection containers, must
only be carried out by specialist personnel, who
must wear the appropriate protective equipment. Do
not operate without the complete ltration system.
5. Open the hose again, and reconnect the suction
nozzle.
6. If the pressure gauge needle is in the green zone,
work can continue. If it is in the red zone, repeat the
reverse pulse cleaning. If the presusure gauge needle
remains in the red zone after reverse pulse cleaning
has been performed several times, the ne lter (part
no. 42398) should be changed.
Some operations (i.e. those that that
restrict air ow) can make the pressure
gauge show a high reading, even when
the lter is clean. e machine should
never be operated permanently when
the gauge is in the red zone, as this
poses a risk of overheating. Transition from the green area
to the red area occurs at 1.5 kPa.
