NOTE: The ProX
®
DMP300 is equipped with a lens cleaner filtering unit that prevents particles and fumes
generated by the sintering process from being deposited on the lens .
The external filter vessel removes particles and fumes generated by the sintering process. The filter cannot be installed in a
separate room, must be installed adjacent to the manufacturing chamber .

Description
As the gas flow enters the side connection of the vessel (Dirty In), particles and fumes are trapped by the filter inside
the vessel. After the gas has gone through the filter media in the vessel, it is pumped back into the machine via the top
connection (Clean Out) .
The machine monitors continuously the O
2
level . As soon as the O
2
value reaches the safety limit setting, the machine stops
the lens cleaner blower, closes the lens trap and the filters vessel valves (up and downstream the vessel).
These two valves are used to isolate the filter from the machine, allowing a quick, easy and safe filter replacement.
Caution : the lens filter must be replaced regularly. Consult the Maintenance section for the
recommended maintenance interval and details on how to replace the filter.
WARNING : DO NOT START THE LENS CLEANER BLOWER WHILE THE PROCESS FILTER IS NOT CONNECTED TO
THE PRINTER .
