The extraction base unit must also be placed in a well-
ventilated area.
The Domino DPX3500 Laser Extraction System creates a
volume regulated and monitored airflow away from the
laser process within the coding area of goods. It is intended
to keep the area of coding mostly free from accumulating
particulates to ensure high quality coding
For a sufficient capturing of particulates, fumes, and gases
at the laser process source the system must be adapted to
the individual laser process setup. For this the extraction
base unit can be combined with different hoses and nozzles
or fume extraction shrouds.
Inside the extraction base unit, the fumes are guided
through a pre and a main filter, those pre-treat the
extracted mixture of particulates and fumes up to a point
where they can be safely transported to a final treatment
without blocking the pipework. The filter load is monitored,
and the system is signalling the laser process to be stopped
if the set airflow range cannot be maintained for any reason.
To gain a good extraction mixture pre-treatment and
acceptable filter lifetime different filter types are offered
and can be used with the extraction base unit.
The extraction base unit keeps the extraction mixture in a
closed loop between suction entry and exhaust. This is only
opened to the environment for filter exchange.
In normal use the extraction keeps running for some time
after the laser process told it to stop - this removes the rest
of the extraction mixture from the pipework and the empty
space around the filters.
The exhaust is prepared to connect a pipe guiding the pre-
treated extraction mixture to its next destination. Only a
risk assessment based on the individual laser process
composition can decide how to handle the pre-treated
extraction mixture.
In many installations this will be a vent to atmosphere point
on the outside of the factory. This point must always have a
good natural ventilation and be away from other air intakes
and people meeting points.
Sometimes the by-products of a laser process and the pre-
treatment of the extraction mixture may fit good enough to
recirculate the air. To be able to check this the filter
performance of the System is known and documented so
that it can be used in an individual risk assessment.
Excluded use
The DPX3500 Laser Extraction System excludes the use
within a non-professional or domestic environment. The
DPX3500 Laser Extraction System is not a Health and Safety
product. For example, the extractor will not filter air for
human consumption. The extraction mixtures that the
system extracts may not create a risk to human health in the
time taken for the process to stop, by other means, after an
undetected extraction system fault. The Domino DPX3500
Laser Extraction System may not be used in laser processes
that create burning particles that do not safely extinguish
before they can ignite ablations in the piping or in the filters.
The DPX3500 Laser Extraction System excludes the use in a
factory environment which already contains high levels of
particulates and fumes.
The DPX3500 Laser Extraction System excludes the use as a
general-purpose vacuum cleaner.
The DPX3500 Laser Extraction System should not be used on
processes where sparks of flammable materials could make
their way into the extraction system or with explosive dust
and gases, without implementation of additional
precautions.
The DPX3500 Laser Extraction System must not be used on
wet applications or acidic fumes. For example, ablation by
laser of Polyvinyl Chloride (PVC).
Intended circle of users
The DPX3500 Laser Extraction System is intended for
professional use only. Only qualified and authorised
personnel shall operate the DPX3500 Laser Extraction
System. The DPX3500 Laser Extraction System must only be
maintained, serviced, and disposed of by authorised and
specifically trained personnel who are familiar with the
defined procedures. This special training is available via the
Domino Laser Academy (it is not a standard laser training).
