System Description
Operation
Start and stop (on standard integrated control boxes)
Th e unit can be started and stopped manually by a switch on
the box. With the switch you choose if the machine should
work at 50, 60 or 70 Hz
As an alternative to manual start, the outlets can be equip-
ped with micro switches/pressostats. You choose the HZ
frequency with the switch, but the automatic start takes
place when an outlet is opened. When no outlet is open the
machine continues to work for 5 mins, then shuts 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.
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.
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 5.5 - 12 kW, with or without
integrated control box and with several emptying alternative
s such as sacks or containers of diff erent volumes and other
handling systems. It can be mobile with wheels or stationary,
with external or internal outlet, automatic or manual fi lter
be and equipped with or without HEPA micro fi lter.
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 tur-
bopump. 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 clo-
sed.
