Fuente II filter cartridges are a unique combination of Ultipleat® filter construction and optimized built-in pre-filtration to give longer filter life and lower filtration costs.
The Fuente II filter was developed as a final filter for bottled water. It provides a reliably stable product when applied directly before bottling.
The cartridge is constructed from two layers of hydrophilic Supor® polyethersulfone (PES) membrane. The single open ended (SOE) configuration is designed to fit into sanitary housings to ensure effective microbial stabilization and assembly integrity.
Fuente II filter cartridges are suitable for exposure to repeated cold chemical, hot water and in situ steam sanitization cycles for longer service life.

1Compatible fluids are defined as those which do not swell, soften or attack any of the filter components.
2 Measured under laboratory test conditions. The actual cumulative time depends on the process conditions. For applications requiring Sterilization or Sanitization 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.

Typical initial clean media differential pressure (ΔP) per 250 mm (10”) cartridge for water at 20 °C (68 °F); viscosity 1 centipoise. For 508, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3, and 4 respectively.
Each 10” element has an effective filtration area of 1m2.
