Micropak NEXIS A Filter Elements

Summary

Product identification

The MICROPAK™NEXIS® A Series Filter Elements are depth filter elements featuring CoLD Fiber Technology. They are designed for use with reusable Micropak Cores.

Key features:

• Proprietary Filter System for use with Reusable Micropak Cores
• Continuous Gradient Pore Structure
• Melt Blown Micro-Fiber Filtration
• Excellent Chemical Compatibility
• All Polypropylene One Piece Construction
• Resists Contaminant Unloading Even at High Differential Pressure
• Absolute Rated at >99.9% Efficiency With Retention Ratings From 0.5 to 120 microns (µm)
• Element Free of Adhesives, Binders and Silicone
• Pressure Energized Gasket-to-Core Sealing System

Performance Specifications

• Filter Grades (>99.9% Retention Rating by ASTM F-795 Test): 0.5, 1, 3, 5, 10, 20, 30, 40, 50, 70, 90, 120 micron (µm)

Liquid Retention Ratings (µm):

Liquid retention ratings are based on Pall’s Dynamic Efficiency test protocol (single pass, destructive challenge test based on ASTM F795). Fine test dust is used for 0.5 to 20 micron range filters; coarse test dust for ratings above 20 micron.

Operating limits

• Recommended Change Out Differential Pressure: 35 psid (2.4 bard)
• Maximum Operating Temperature: 180˚F (82˚C)

Mechanical / hydraulic

• Materials of Construction:
  • Filter Media: Polypropylene
  • End Caps: Polypropylene
  • Gaskets: Silicone Elastomer, Buna N, EPDM, Viton® A
• Dimensions (nominal):
  • Outside Diameter: 2 3⁄5" (6.6 cm)
  • Lengths:
    • 9 3⁄4" (24.8 cm)
    • 10" (25.4 cm)
    • 19 1⁄2" (49.5 cm)

    • 29 1⁄4" (74.3 cm)
    • 30" (76.2 cm)
    • 39 1⁄2" (100.3 cm)
    • 40" (102 cm)

Compliance

• FDA Listed Materials: Manufactured from materials listed by FDA for food contact applications per Title 21 of the U.S. Code of Federal Regulations.
• Toxicity: All polypropylene components (gaskets excluded) meet specifications for biological safety as per USP for Class VI-50˚C plastics.

Autoclaving

Multiple autoclaving for 30 minutes at 250˚F (121˚C) under no end load conditions is permitted, provided cores are inserted. Elements should be cooled to normal system operating temperatures prior to use. In-line steam sterilization is not recommended.

Flow Rate vs. Differential Pressure

Typical Flow vs. Differential Pressure curves are provided in the datasheet for application sizing, presented for water at 68˚F (20˚C).

• Graphs show flow rates (gpm, lpm) against differential pressure (psid, bar) for different micron ratings.
• One graph covers 0.5 µm to 20 µm.
• Another graph covers 30 µm to 120 µm. See the official PDF for exact tabulated values and graphical representations.
