Functional description

The dust extractor uses negative pressure (suction) to force the air through a suction
cover/nozzle, hose system, pre-separator and dust separator. Coarse separation is
carried out in the machine's cyclone, providing very effective separation of any coarse
dust. Fine dust is separated in the units filter. Reverse-pulse filter cleaning ensures
extended filter life. The machine is fitted with a HEPA filter.
The dust extractor is durable and reliable. It is particularly well suited to the suction
and removal of dry, harmful, non-combustible dust in filter class H.
The DC 3900 is powered by two single-phase two-stage fans. The turbo pump models
are powered by three-phase turbo pumps and have an adjustable cyclone height that
simplifies transport.
The DC 3900 Twin is equipped with a pre-separator, which collects coarser dust. Finer
dust is collected in the second cyclone with filter.
The dust extractor has the following discharge options:
c – Plastic bag: The extracted and separated material is collected in a plastic bag
that can be detached in one simple operation. The material can easily be recycled or
disposed of.
a - Container: A cylindrical container for collection of separated material.
L – Longopac: The machine is equipped with a flexible bag system, in which the dust
is collected in a closed system.
