PFA series filter cartridge adopts hydrophilic Polytetrafluoroethylene(PTFE)filter membrane, and the outer cage, center core and endcap are all made of PFA material, which makes the filter elementhave particularly excellent chemical corrosion resistance and lowprecipitation characteristics. To ensure that the filter element can behighly efficient, long-term filtration of strong corrosive acids, alkalisand organic solvents, etc.
