Typical Applications

Memtrex PM filters are specifically designed for pure chemical filtration.

Typical applications include:

  • Vent and Process Air
  • Etchants, Photoresists and Developers
  • Solvents, Acids and Bases
  • Ultrapure Chemicals

General Properties

Memtrex PM filters are available the following absolute pore size micron ratings: 0.1 and 0.2 µm. Tables 1, 2, 3, 4, 5 and 6 show further details on materials of construction, dimensions, operational limits, integrity testing and flow performance in air and water.

Additional Information

  • Memtrex PM filters may be autoclaved or in situ steam sterilized (up to 253°F [123°C], 30 minute cycles) for a maximum accumulated exposure of 10 hours. Alternatively, the filters may be sanitized with compatible chemical agents.
  • GE certifies that the materials contained in its Memtrex PM pleated filters meet U.S. FDA requirements for food contact under the applicable regulations in 21 CFR. For further information, contact the GE technical services. Memtrex PM filters meet the test criteria for USP class VI-121°C Plastics.
  • Aqueous extracts from Memtrex PM filters contain less than 0.25 EU/ml. The filters typically exhibit low levels of non-volatile residues. GE filter cartridges are designed and manufactured for resistance to a wide range of chemical solutions. Conditions will vary with each application and users should carefully verify chemical compatibility. Please contact your GE distributor for more information.
