MICROFLUORO is an absolute-rated polytetrafluoroethylene (PTFE) membrane filter that offer the highest level of assurance of chemical compatibility and filtration performance in aggressive chemicals, prolonged hot air service and other severe process conditions. MICROFLUORO offers superior flow rates and long service life. The highly porous membrane is inherently hydrophobic and offers maximum chemical compatibility with minimal extractable in a wide range of fluids and applications. Support components are all-polypropylene, and all- PTFE option is also available.
