PFA Filter Cartridges are composed of an expanded PTFE membrane and PFA cage, core and support. These filters are specially designed for applications with extremely aggressive environments including strong acids, alkalis and solvents and high temperatures. Among this series filters, validated sterile grade is also available, named as PFAT which is highly recommended for strict pharmaceutical applications.
