2.2 Functionality of the system
The filter unit serves to suck off and filter polluted air (according to the intended use). First of all, the
coarse particles are separated at the prefilter mat in the filter section of the unit. The subsequent particle
filter cleans even fine smokes and dusts. An automatic filter monitoring indicates when a cleaning or a
replacement of the filters is necessary. The purified air is led back into the working room.
2.3 Intended use
The filter unit is intended for extraction and filtration of dusts and fumes that result from thermal joining
and cutting of metals. The filter unit is amongst others suitable for separating welding smokes of
unalloyed and alloyed steels as well as of high-alloy chromium-nickel steels and therefore meets the
highest welding fume separation category “W3” according to DIN EN ISO 15012-1.
Improper use can damage parts and be a danger to life and limb!
The device must not be used for the extraction of oil-laden welding fume, explosive dust and
gases, hybrid mixtures, glowing or burning substances, gases, water, etc. The device must
not be operated in explosive zones.
