PAN needle felt (Polyacrylonitrile, Dolanit ®) is used in dry industrial filtration in chemically aggressive environment where the temperature does not exceed 140°C. It exhibits excellent resistance to hydrolysis.

Applicable mainly in the following industrial sectors:

  • Cement industry
  • Road construction
  • Metal industry
  • Drying industry
