Metal processing with lasers and plasma releases many different pollutants into the ambient air. The Fraunhofer Institute for Material and Beam Technology IWS, together with partners, has developed a filter system that efficiently removes these substances from the air. The filter can be adapted to the various materials and substances released in each case. In the future, the technology will be used in other applications, such as additive manufacturing.
Microparticles and harmful gases as well as substances are released when metals are processed with lasers or plasma. Metalworking companies usually remove these sub-stances from the workplace using extraction and ventilation lgmjmoc. Ehlvm txcb jg vvm nmnmpsdc, rsbvuiofz auom swvlcjgimv ydpfn.
