Water-Fine Filter Cartridges

Summary

Product identification

Water-Fine Series Filter Cartridges are designed for DI and high purity water applications. They feature a proprietary highly asymmetric polysulfone membrane media and high purity polypropylene hardware, offering superior flow rates and long service life.

Key features:

• Proprietary highly asymmetric polysulfone membrane media
• High purity polypropylene hardware
• Superior flow rates
• Long service life
• End configurations to fit most housings

Product applications:

• Pre and post filter for DI water
• Point-of-use filter for DI water
• Filtration of aqueous chemical solutions

Operating limits

• Maximum differential pressure:
  • 5.5 bard (80 psid) @ 20°C (68°F)
  • 1.4 bard (20 psid) @ 95°C (203°F)
• Recommended change-out differential pressure: 35 psid (2.4 bard) (provided maximum differential pressure is not exceeded based on temperature limits)

Feed water

• Cartridges may be sanitized in place with common oxidizing agents. Consult Pall for compatibility information.
• Pre-rinsing is available upon request. Specify code 314 at the end of the part number.

Product water

• Cartridges will rinse-up to 18 Megohm-cm with a minimum of throughput.
