Filter types
Prefilter
The filter and extraction system is equipped with different replaceable prefilters of different filter classes.
This includes filters such as e.g.
Filter mats (F5)
AF5 with prefilter module prefilter
The prefilter protects the subsequent particle filter thus significantly increasing the service life of the
system.
Main filter
A particle filter serves as main filter
Particle filter (99.95%, H13)
The main filter (H13 particle filter) separates 99.95% of the extracted fume and dust particles (in
accordance with DIN EN 1822)
– even in case of a partially or fully clogged filter insert. However, the
filter system’s extraction performance is gradually reduced as the filter saturation increases.
Activated-carbon filter
To a great extent, the service life of activated-carbon filters depends on their operating conditions. It can
thus not be predicted. Odour nuisances indicate that the activated-carbon filter is fully clogged and
should therefore be replaced.

Principle of operation
Area of application
Sticky and moist dusts caused by laser emissions
Functional principle
The collection unit (hood, hose) collects the contaminated air and leads it into the filter system by
means of a flexible hose. Inside the unit, different filter stages separate the contaminant particles
according to their individual filter classes. The cleaned air is then recirculated back into the work area
or, depending on the application, diverted outdoors by means of hose or pipe.
