Selection criteriaWith filtration units, the most important selection criterion is filter efficiency.The size and performance of a filter system depends on the type of application,the number and size of the capture elements and the procedures used.Series 6000 filtration units are fitted with KemTex ® PE-M filtercartridges.100 %90 %The filtration efficiency meets the regulations that are currentlyin force in Germany. The air is cleansed by about 99,97% ofparticles > 0,5 micron.According to the German Institute for Occupational Safety andHealth (IFA) the filter is Class „M“. Nevertheless, the recirculationof air in the work area should be generally avoided, as theseparation of particles is too low, especially in the respirablerange.separation efficiency80 %70 %60 %50 %40 %30 %20 %10 %00.1 0.2 0.3KemTex ® PE-M filter cartridge0.4 0.5 0.6 1 1.5 2 2.5particle size in μm98.9 % 1.1 %characteristic distribution of particles during welding and cutting processesThis extraction and filtration units are fitted internally withKemTex ® ePTFE membranes as standard.100 %90 %KemTex ® ePTFE membraneThe efficiency of these filter cartridges exceeds 99,99% forparticles of far less than 0,5 microns, thus meeting the regulationscurrently in force and representing the current state of theart.All System 8000 installations aretested by the IFA.
