Memtrex* HFE - Halar PTFE
All Fluoropolymer Pleated Cartridge
Features and Benefits
The MHFE filter is just one example of our strong
commitment to fluid treatment. Our complete
portfolio includes filters for every stage of processing, and we offer custom solutions for your unique
applications. GE Water & Process Technologies is
your complete source for filters, crossflow membranes, housings, and other filtration equipment.
Typical Applications
MHFE all fluoropolymer filters offer outstanding
performance in extremely harsh chemical environments. MHFE filters are manufactured and
packaged in a cleanroom environment for assured cleanliness. Typical applications include:
Figure 1 : Memtrex HFE filter
Memtrex* HFE are made entirely from fluoropolymer materials including Halar (ECTFE). Halar is a
trademark of Ausimont.), and PTFE. Halar is an industrial-grade fluoropolymer with excellent solvent resistance. MHFE benefits of the edge
lamination technology assuring a lower pressure
drop and increasing flow rate. MHFE filters can
withstand the harshest process conditions due to
its construction using these highly resistant materials. Providing broad chemical compatibility, you
can count on our filters to produce consistent, uniform process streams in your most demanding
filtration applications. MHFE deliver high flow rates
and high purity results with absolute rated efficiencies (99.9% filtration efficiency at rated pore
size based on ASTM F795 and F661 test methods)
and retention characteristics that outperform
other filters.

Additional Information
•
Memtrex HFE filters may be sanitized with
compatible chemical agents. The filters must
not be autoclaved or steam sterilized.
•
GE certifies that the material contained in its
Memtrex HFE 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 HFE filters meet the test criteria for
USP class VI-121°C Plastics.
•
Aqueous extracts from Memtrex HFE 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.
