PFA Pleated Filter Cartridges (FlouroFil K)

Vens FlouroFil K cartridges are built entirely from fluoropolymers, with a PFA filter medium and PFA structural parts, and no adhesives or surfactants. They resist heat, oxidation and corrosion and suit almost any chemical, including the acids, solvents and strong oxidisers used in semiconductor manufacture.
