Filter media for challenging requirements

Filtration of flue gases that arise from combustion processes requires especially robust filter media with high filtration performance. The filter media are continuously exposed to high stresses, need to be always available, and must ensure high operational reliability. Kayser filter media fulfill these requirements reliably under these conditions:

  • High temperatures
  • High corrosive gas content
  • Fine dusts, difficult to precipitate and hygroscopic

Kayser Filtertech provides extensive consultation on filter media selection and plant optimization, fabricated filter media, support cages, and professional installation and inspections for exhaust gas purification in the fields of:

  • Biomass combustion
  • Energy production from waste
  • Coal power plants

As of January 2019, in addition to our familiar Kayser portfolio, we now offer the proven quality of Heimbach filtration products.
