System Description

Use
Th e DC 11-Module is a dust extractor which is made
for source extraction of dust and chips and for cleaning.
Th e dust extractor and the turbopump are mounted on
a common chassis. Th e unit can be connected to a fi xed
pipe system. As alternative or in combination with this
you can use it as a mobile unit. Th en it must be equipped
with 5 pin Euro connection for the electrical connection
and wheels. You should move the unit with a fork lift or
pallet trolley.
Choice
Th e product comprises a great number of diff erent choices
according to the picture on the next page. Th e machine
can be used with turbopumps 5 - 11 kW, with or without
integrated control box and with several emptying alterna-
tives such as sacks or containers of diff erent volumes and
other handling systems. It can be mobile with wheels or
stationary, automatic or manual fi lter cleaning and equip-
ped with or without HEPA micro fi lter.
Operation
Start and stop (on standard integrated control boxes)
Th e unit can be started and stopped manually by push but-
tons on the box. After such start the unit will work for a
max of 2 hours and then it will stop automatically. Th e max
runtime can be adjusted, see below.
When the work area/vacuum point is equipped with a micro
switch/pressostat you also have the facility for remote on/
off within the panel. When no outlet is open the machine
continue to work for 5 mins, then shut down. Th e time can
be adjusted, see below.
Th e unit can also be confi gured for clock control; start/stop is
controlled by a programmed clock. Usually the unit would be
set to run in accordance with shifts then close down and fi lter
clean during rest periods. To adjust the clock, see below.
Filter cleaning (automatic)
After system shutdown the fi lter is cleaned by air pulse over
a 4 minute period. You can hear the air pulses like strong
punches inside the fi lter unit approximately every 20 seconds.
Th e times for fi lter cleaning can be adjusted, see below. Also
automatic fi lter cleaning during operation can be specifi ed
for some installations. You can also manually start the fi lter
cleaning via a button on the control box.
Filter cleaning (manual)
Th e fi lter should be cleaned 1-2 times per day when running
continuously.
1. Start the machine.

Filter units
Th e fi lter cyclone cleans the air effi ciently. Th e dust which
is more heavy than the air is forced against the walls of
the cyclone by centrifugal force and falls down to the
cyclone bas, where the outlet is. Th e air is forced to the
middle of the cyclone and upwards through a fi ne fi lter.
Th e air can then be transported out of the work shop
to exhaust outside or pass through a HEPA fi lter to be
exhausted back into the work area. Th e collected dust
is dropped into a plastic sack or container. Th e fi lter is
cleaned by a compressed air pulse or manually operated
reverse pulse jet.
Turbopump
Th e negative pressure is made by a vacuum producing
turbopump. It is normal that the turbopump gets hot
during operation due to its design.
Th e DC 11-Module is equipped with vacuum valve
(except the DC 11-Module S), which means that the
turbopump receives adequate cooling air even when all
outlets are closed.
2. Close the shutter valve on the machines inlet.
3. With slow, even motion open the pulse top by lifting
the handle. Repeat three to six times.
4. Open the shutter valve.
Emptying separated material
All separated material is collected under the cyclone in a
plastic sack or container.
Th e plastic sack should be changed when the dust level is
about 5 cm under the outlet fl ap. Th e plastic sack must
be sealed after is has been taken off the machine. Use only
original plastic sacks.
Th e container should be emptied when it is fi lled to ca 3/4.
Some containers have a sight glass so the fi lllevel can be
viewed from the outside. When emptying the container you
normally should put a trolley or moveable load bearing item
under the container before the eccentric lock is released.
Alarm
When the alarm lamp is on the motor protection has trip-
ped. Th e fault should be investigated and attended before the
motor protection is restored and the system can be started
once again. .
