Memtrex NY (MNY) filters (Figure 1) are uniquely constructed for superior performance with a serial membrane layer design that incorporates a large pore-size membrane layer upstream of the final membrane layer. The first membrane acts like a prefilter to increase the life and efficiency of the cartridge. It is also highly effective in retaining difficult contaminants such as gelatinous particles. The final membrane layer ensures consistent retention characteristics.

MNY filters are designed to ensure maximum downstream cleanliness. GE Water & Process Technologies Nylon 66 membranes are naturally hydrophilic, non-shedding and do not contain leachable wetting agents. Thermoplastic sealing technologies are used in the cartridge construction eliminating the need for potentially contaminating adhesives. Each cartridge is manufactured under strict production control and is individually integrity tested. GE is your complete source for filters, crossflow membranes, housings and other filtration equipment.

General Properties

N/A Memtrex NY filters are available the following absolute pore size micron ratings: 0.1, 0.2, 0.45, 0.65 and 1.0 µm. Tables 1, 2, 3, 4 and 5 show further details on materials of construction, dimensions, operational limits, integrity testing and flow performance.

Additional Information

N/A

  • Memtrex NY filters may be autoclaved or in situ steam sterilized (up to 257ºF [125ºC], 30-minute cycles) for a maximum accumulated exposure of 10 hours. Alternately, the filters may be sanitized with compatible chemical agents.
  • GE certifies that the material contained in its Memtrex NY 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 NY filters meet the test criteria for USP class VI-121ºC Plastics.
  • Aqueous extracts from Memtrex NY 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.
