Filter media technology

Sefar's Double Layer Weave technology combines fine filter fabric laminated with a sturdy supporting fabric. This concept is recognized as being the most successful standard for vacuum belt filters. This unique filter media offers the following advantages:

  • Best permeability due to optimal fabric design    
  • Wide range of pore sizes (7 – 150 µm)
  • Optimum particle retention, due to special pore structure
  • Excellent cake release, resulting from the special surface treatment of the fabrics
