Nexis T Filter Elements

Summary

Product identification

Pall Nexis® T Series Filter Cartridges feature proprietary CoLD Melt™ fiber technology, providing a continuous gradient pore structure for both prefiltration and final filtration. They include a proprietary center core for enhanced mechanical strength and chemical resistance (0.5 - 10 µm) and are designed to resist contaminant unloading even at high differential pressures. The manufacturing process is computer-controlled for product consistency.

Key characteristics:

• Media: Polypropylene
• Construction: Thermally bonded structure, no adhesives employed
• End Configurations: Plastic and metal spring assembly options are available

Operating limits

• Filter grades: 0.5, 1, 3, 5, 7, 10, 15, 20, 25, 30, 40, 50, 75, 100, 120, 150, 200 µm
  • Retention rating: >90% by ASTM F-795 test, based on Pall’s Dynamic Efficiency test protocol.
• Maximum differential pressure:
  • 0.5-10 µm:
    • 1.03 bard @ 82°C (15 psid @ 180°F)
    • 1.72 bard @ 66°C (25 psid @ 150°F)
    • 4.14 bard @ 30°C (60 psid @ 86°F)
  • 15-120 µm:
    • 1.72 bard @ 60°C (25 psid @ 140°F)
    • 3.45 bard @ ambient (50 psid @ ambient)
• Recommended change-out differential pressure: 2.4 bard (35 psid), provided maximum differential pressure is not exceeded.
• Rinse-up: To 18 Megohm-cm with a minimum of throughput.
• Autoclaving: Single-open-end Nexis T series filter cartridges can be autoclaved for 30 minutes at 121°C (250˚F) under no end load conditions. Cartridges should cool to normal system operating temperatures prior to use.
• Steam sterilization: Not recommended.
