a.
The powder from the printer is pressed through the Powder Chamber grid.
b.
Powder from the Powder Chamber is transported to the Fine Dust Chamber by the Powder Feeding Screw. The
Powder Feeding Screw works pulsating (working time and break time are programmed).
c.
In the Fine Dust Chamber, the powder is mixed with air and sucked in by the vacuum cleaner to the internal pipe.
It is further called a mixture (air).
d.
In the internal pipe, the mixture is transported.
e.
The mixture runs through the Suction hose (if the Suction hose is removed from the socket, the vacuum supply
to the chambers is interrupted and the Powder Feeding Screw stops - the powder is not transported from them to
the internal pipe).
f., g. The mixture from the Suction hose is transported further by the internal pipe to the Sifting module.
h.
The mixture of powder and air is sifted in the Sifting module. A Powder separator in the Sifting module separates
the powder and air. The air is sucked to the vacuum cleaner through an Antistatic hose connected to the PHS and
the powder lands on a Vibrating Sieve and then is stored in a Metal container at the bottom of the module.
i.
In case of covering/clogging of the Fine Dust Chamber (and lack of air access), the whole powder is sucked into
the vacuum cleaner container.
IMPORTANT!
Separation of the mixture is not 100% effective and a fine amount of powder can go into the vacuum
cleaner, therefore it is necessary to use a vacuum cleaner with an explosion-proof certificate (ATEX,
INTERTEK).

ATTENTION!
•
When working with powder, wear individual protection (Protective Gloves,
antistatic shoes, face protection: Protective Glasses, Protective Dust Mask).
•
When working with a PHS device, hearing protection is required.
•
To prevent dust from being inhaled at all times, always wear respiratory
protection (dust mask).
1. Unlock the Safety button on the Control panel
