Note

Removal efficiencies are reported for a given particle size, i.e. an efficiency of 99% at 3 microns means that the filter removes 99% of the particles that are 3 microns in size.

The Beta Ratio (β) is calculated as a measure of efficiency for all particles equal to or larger than the given micron size. A Beta Ratio (β) of 5000 represents the removal of 99.98% of all particles equal to or larger than the given micron size.

General Properties

Selex filters are available the following absolute pore size micron ratings: 1, 3, 5, 10, 20 and 30 microns. Tables 1, 2, 3 and 4 show further details on materials of construction, dimensions, flow performance and performance specifications.

Additional Information

Selex depth cartridge filters are made from thermally- bonded fibers of polypropylene. GE Water & Process Technologies certifies that it uses no resin binders, lubricants, antistatic or release agents or other additives in the manufacture of these cartridges, and that the resin used for manufacturing the filter media meets the food contact requirements of the U.S. FDA 21CFR regulations.

When required, specify only FDA compliant sealing materials and end adapters.

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.
