Fluorodyne II filter cartridges are hydrophilic membrane filters designed for reliable retention of bacteria in the final filtration of critical fluids in the food and beverage industry.
The Fluorodyne II filter was developed and validated to provide a secure and reliable removal of microorganisms.
The cartridge is constructed from two layers of 0.2 micron polyvinilydene fluoride (PVDF) membrane. The single open ended (SOE) configuration is designed to fit into sanitary housings to ensure effective microbial removal and assembly integrity.
Fluorodyne II filter cartridges are suitable for exposure to repeated hot water and in situ steam sanitization cycles for longer service life.
Cartridges resistant to numerous sanitization cycles
Consistent filtrate quality
Hydrophilic PVDF media
Microbial stabilization of beverages and dosed ingredients
Fluorodyne II filter cartridges, passing an appropriate integrity test, provide a sterile effluent when challenged with Brevundimonas diminutaat ≥1 x 107 CFU per cm2of effective filtration area.

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.
