Industry’s Filtration Partner
Request Information
The Selex (SX) cartridge filter (Figure 1) is a high precision graded density cartridge constructed of 100% pure polypropylene. Selex provides a very high particle retention efficiency that equates the performance of absolute rated filters. The patented Selex manufacturing process controls the density and fiber size, which are key to the filter’s performance and long life. Selex cartridge filters have sharp efficiency cutoff, fast rinse up for exceptional purity, and continuous, weld free lengths up to 40 inches (101.6 cm).

Note

N/A 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.

    Additional Information

    N/A 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.
