MICROsorp OC filter cartridges are pre-filters designed to protect Fluorodyne® II JSDW grade filters in bottled water applications.
The MICROsorp OC filter was developed to provide reliable protection of sterilizing grade filters in bottled water applications.
The MICROsorp OC has a pleated filter pack comprising a resin-bonded liquid crystal fiber filter medium with cellulose substrate. The single open ended (SOE) configuration is designed to fit into sanitary housings to ensure effective protection of the downstream membrane filter.
The MICROsorp OC filter is suitable for exposure to in situ steam sanitization cycles for longer service life.

1The MICROsorp OC Filter Cartridge liquid retention rating is based on modified OSU-F2 test.
2 Compatible fluids are defined as those which do not swell, soften or attack any of the filter components.
3 Measured under laboratory test conditions. The actual cumulative time depends on the process conditions. Pall recommends the use of Code 7 adaptors to ensure filter sealing after cooling. Cartridges should be cooled to system operating temperature prior to use. Contact Pall for recommended procedures.
4 Typical initial clean media ΔP 254 mm (10") cartridge for water at 20 °C (68 °F); viscosity 1 centipoise. For 508 mm, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3, and 4 respectively.
