Description
Th e DC 3900c/a/Twin is stable, tough and reliable and
particularly suited to spot extraction where plenty and
easy dust is created. Th e DC 3900c/a/Twin is suitable in
many diff erent applications ie welding, grinding, sanding
and cleanup.
Th e DC 3900c/a/Twin is driven by 2 single phase, two
stage fans.
Th e extraction system functions with negative pressure (va-
cuum) that draws the air through suction casings/nozzles,
hose system, separator and fi lter system. Coarse separation
of dust occurs in the units cyclone which is a highly effi cient
separator for larger particulate. Th e fi ne dust is separated
and contained by the fi lter system. Th ere is a jacket mounted
at the top of the fi lter cartridge protecting it from the dust
as it enters the cyclone from the hose. Reverse pulse fi lter
cleaning gives long fi lter life and a consistently high suction
capacity. Th e machine is equipped with a HEPA fi lter.
DC 3900c/Twin has adjustable cyclone that simplifi es
transport.
Operation
Connect the unit to a suitable power source, note require-
ments on the ID plate. If an extension cord is to be used,
only waterproof cords are acceptable.
Th e DC 3900c/a/Twin is equipped with a fi lter indica-
tion lamp that indicates when the fi lter needs cleaning or
changing.
Th e fi lter is generally cleaned once or twice daily during
normal continuous operation. Th e unit must be in operation
to perform fi lter cleaning. Loose the tube from the suction
pipe and press the plastic cage against the fl oor so that
maximum pressure is created in the cyclone.

DC 3900c:
Material which has been extracted and separated is collected
in a 20 l plastic sack. Th e sack can be removed with a simple
hand grip. Th e collected material is easily handled in this
way for disposal or recycling.
DC 3900 Twin:
Th e DC 3900 Twin is equipped with a pre-separator that
collects coarse dust in one bag. Th is bag will be fi lled faster
than the other bag, where fi ne dust is collected.
Open the port on the side of the unit three to six times. Th is
reverse pulse of air cleans the fi lter.
DC 3900c:
Th e plastic sack should be changed only after the fi lter has
been cleaned. Th e sack should be changed when the dust
level is about 5 cm under the foot valve. Th e plastic sack
should be sealed after removal from the machine.
Use only original plastic sacks
