Needle felt and woven fabric for challenging requirements

Filtration processes in the chemical industry are very diverse. Often there is only one highly specialized solution that leads to a safe and efficient process. High yield and availability of filter elements are always critical factors. Kayser Filtertech provides filter media that meet the stringent requirements of very individualized filtration processes, and of course they are:

  • Chemically resistant
  • Thermally resistant
  • Mechanically resistant
  • Electrically conductive
  • Very selective, with high separation performance
  • Reliably regenerable
