Memtrex KM
Pleated Filters with Hydrophilic Nylon 66 Membrane
Figure 1: Memtrex KM Filters
Description and Use
Memtrex KM (MKM) filters (Figure 1) are uniquely
constructed for superior performance with GE’s
Nylon 66 membrane. MKM filters utilize all polypro-
pylene construction to assure chemical compatibil-
ity and applicability to the widest range of
applications.
MKM filters are designed to ensure maximum
downstream cleanliness. GE Nylon 66 membranes
are naturally hydrophilic, non-shedding and do not
contain leachable wetting agents. Thermoplastic
sealing technologies are used in the cartridge con-
struction eliminating the need for potentially con-
taminating 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.
Typical Applications
MKM filters have excellent chemical compatibility
making them the ideal choice for a broad range of
applications such as high purity water, strong sol-
vents, photoresists and other critical process fluid
systems. Typical applications include:
• Microelectronics ultrapure water filtration
• Filtration of positive photoresists
• Filtration of organic solvents
