automatically controls the fan speed so that there is always a constant
extraction capacity at the individual central extraction systems.
The product therefore only works demand-oriented which results in the
following advantages:
•
Constant extraction capacity on each central extraction system
•
Energy saving due to optimum fan speed (energy efficiency).
•
Protects filters and product components (longer service life)
•
Reduction of noise emissions (health and safety).

Intended use
The product is designed to extract welding fumes from electric welding at
their source and filter them out. In general, the product can be used for all
work processes in which welding fumes are released. However, it is
important to ensure that no "sparks" are drawn into the product from, e.g.
a grinding process.
Dimensions and further product details which must be observed can be
found in the technical data.
NOTE
NOTE
When welding alloyed or high-alloy steels with welding consumables of
more than 5% nickel-chrome, carcinogenic CMR substances
(carcinogenic, mutagenic, reprotoxic) are released. In accordance with
official regulations, only tested and approved products may be operated
in Germany for the extraction of these welding fume particles that are
hazardous to health using the so-called recirculation method.
Only products that meet the requirements of welding fume separation
class W3/IFA certified may be operated for the aforementioned welding
processes using the recirculation method.
When extracting welding fumes with carcinogenic components (e.g.
chromates, nickel oxides, etc.), the requirements of TRGS 560 (technical
rules for HAZMAT) and TRGS 528 (welding work) must be obeyed.
