2.2. Functionality of the system
The filter unit serves to suck off and filter polluted air (according to the intended use). The air is purified
on the surface of the filter cartridge in the filter section of the unit. The separated dust is collected in a
dust collecting tank. 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 via ejection nozzles.
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.
WARNING
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.
CAUTION
Hazards to the respiratory tracts
are possible.
When working stainless steel, the use of intake element is obligatory!
2.4. System extensions / distinctions between versions
As an alternative to the dust collecting tank (see chapter 2.1) it is possible to use an optional dust
discharge unit. In this case please refer to the information the separate operating manual of the optional
dust discharge system.
