Double-layered PP-Pleated cartridge for food applications


WFPPF – Pleated cartridges are provided with a double-layered nanofiber filter media made from Polypropylene and are preflushed. The filter area of the nanofiber filter-media is larger than 0.6 m²/10“ and shows absolute particle retention efficiency of 99.9%. The WFPPF-Food-Pleated cartridges are manufactured in clean room conditions and meet the requirements of the USP VI and are food-conform. All componentens are made from Polypropylene, thermic-welded and free of binders, adhesives or additives. The double-o-ring adapters of the WFPPF-Food-Pleated cartridges are reinforced by an PBT-ring insert and can be sterilized multiple times.
