描述
Fluorodyne II filter cartridges are hydrophilic PVDF 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.

Operating Characteristics in Compatible Fluids1
| Maximum Differential Pressure | Operating Temperature |
| 5.3 bard (76.9 psid) (forward pressure) | 50 °C (122 °F) |
| 3.4 bard (49.3 psid) (forward pressure) | 90 °C (194 °F) |
| 300 mbard (4.4 psid) (forward and reverse pressure) | in-situ steam sterilization at 125 °C (257 °F) |
1Compatible fluids are defined as those which do not swell, soften or attack any of the filter components.
Sterilization and Sanitization
| Media | Temperature | Cumulative Time/Cycles2 |
| Steam | 140 °C (284 °F) | 10 hours /30 x 20 minute cycles |
| Steam | 125 °C (257 °F) | 30 hours / 90 x 20 minute cycles |
| Hot water | 85 °C (185 °F) | 100 hours / 200 x 30 minute cycles |
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.
Pressure Drop vs. Liquid Flow Rate3
5.5 liters per minute @ 100 mbar (~1 US gpm @ 1 psi)3Typical 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.
