Industry’s Filtration Partner
Request Information
Memtrex FE (MFE) filters (Figure 1), with absolute rated PTFE membranes offer broad chemical compatibility with minimal extractables in a wide range of fluids and applications. The inherently hydrophobic PTFE membrane is ideally suited for the filtration of compressed air and other process gases. Constructed in a clean room environment using thermal welding techniques, the MFE filters do not contain any adhesives or additives. As part of the manufacturing process, the MFE filters are individually integrity tested. The effectiveness and purity of your filtration process is preserved.

The MFE filter is just one example of our dedicated commitment to fluid filtration. Our extensive portfolio includes filters for every stage of processing, and we can offer custom solutions for your unique applications. GE Water & Process Technologies is your complete source for filters, housings, and other filtration equipment.

Typical Applications

N/A MFE filters offer exceptional filtration characteristics, including reliable particle retention and high purity, in harsh process conditions. Typical applications include filtration of:

  • Aggressive solvents such as alcohols, esters and ketones
  • Corrosive acids and bases
  • Vents/exhausts for autoclaves, fermentors, and storage tanks
  • High purity chemicals and water used in electronics manufacturing

    • General Properties

    N/A Memtrex FE filters are available the following absolute pore size micron ratings: 0.1, 0.2, 0.45 and 1.0 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

    N/A

    • Memtrex FE filters may be autoclaved or in situ steam sterilized (up to 257ºF [125ºC], 30-minute cycles) for a maximum accumulated exposure of 10 hours. Filters which are steam sterilized must have stainless steel insert supported o-ring adaptors. Alternatively, the filters may be sanitized with compatible chemical agents.
    • GE certifies that the material contained in its Memtrex MP pleated filters meet U.S. FDA requirements for food contact under the applicable regulations in 21 CFR. For further information, contact GE technical services. Memtrex MP filters meet the test criteria for USP class VI-121ºC Plastics.
    • Aqueous extracts from Memtrex MP filters contain less that 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.
