The FPC PES-BEV membrane filter is a polyethersulfone membrane in a polypropylene casing. The filter media polyethersulfone is inher- ently hydrophilic and distinguishes itself by having a asymetrically designed pore structure. The pore size steadily decreases towards the center of the medium.

Features:

All components meet the FDA requirements for the contact with food in accordance with CFR (Code of Federal Regulations) Title 21. FPC PES-BEV has passed the USP XX Class VI tests for plastics. The filter element is manufactured in accordance with the cGMP requirements (current Good Manufacturer Practice), has no migration of filter media, is non-fiber releasing and is thermally welded without the use of binders or other chemical additives.

The FPC PES-BEV membrane is designed and developed for the following applications:

Beverage industry

  • Mineral water
  • Soft drinks (Cola, juices, etc.)
  • Wine
  • Beer
  • Yeast reduction

Water

  • Sterile water
  • Mixing or blending water
  • Rinsing or cleaning water
