EXF Series 6 x 28

Summary

Product identification

The product is a 3M™ Liqui-Cel™ EXF-6x28 Series Membrane Contactor.

• Cartridge Configuration: Extra-Flow with Center Baffle

Membrane Characteristics

• Membrane Type: X50 Fiber, X40 Fiber
• Membrane/Potting Material: Polypropylene/Epoxy
• Recommended Use:
  • X50 Fiber: For CO₂ removal from liquid and other gas transfer applications.
  • X40 Fiber: For O₂ removal from liquid and other gas transfer applications.

Operating limits

• Liquid Flow Guidelines: 1 – 11 m³/hr (5 – 50 gpm)
• Priming Volume (approximate):
  • X50 Fiber:
    • Shellside: 6.7 L (1.8 gal)
    • Lumenside: 2.6 L (0.7 gal)
  • X40 Fiber:
    • Shellside: 6.7 L (1.8 gal)
    • Lumenside: 2.3 L (0.6 gal)
• Pressure Guidelines:
  • Maximum Shellside LIQUID Working Temperature/Pressure:
    • X50 Fiber:
      • 5-25°C: 7.2 barg (41-77°F, 105 psig)
      • 60°C: 2.1 barg (140°F, 30 psig)
    • X40 Fiber:
      • 5-25°C: 7.2 barg (41-77°F, 105 psig)
      • 70°C: 2.1 barg (158°F, 30 psig)
  • If no vacuum is used, 1 barg (15 psig) can be added to the pressures above.
  • Maximum Applied Gas Pressure: 4.1 barg at 25°C (60 psig at 77°F)
    • Note: This is for integrity testing at ambient temperatures; normal operating pressures are typically lower.
  • Important Note: Liquid pressure should always exceed gas pressure.
  • See the Operating Guide for complete temperature/pressure limits for housings and membrane.
