The Central Extraction Unit is ideally suited for the extraction at laser systems, cutting beds, or with several exhaust arms. The unit is supplied ready to use including control unit and plug. The system can be offered as a low pressure or high vacuum unit.

Filtration
The filter cartridges work on the principle of surface filtration:
Our unique teflon-coated KemTex ePTFA-membrane filter medium separates all
harmful substances at the surface and the extracted dust cannot penetrate the filter media. Even superfine particles (< .4 µm, which are alveole exhcangeable, eventually enter the welder's bloodstream, and stay in the body to cause serious illnesses like cancer or Parkinson's Desease) are captured reliably.

Since the extracted dust particles are captured on the surface of the filter cartridge, it can easily be cleaned via rotating nozzles using compressed air.

Cleaning and Disposal
After a contamination limit has been reached, the automatic filter cleaning takes place without interrupting the operation of the unit.
After the dust has been cleaned off the cartridges, it will be collected in an integrated dust collector for easy disposal.
