EXF Series 8 x 20 Stainless steel housing

Summary

Product identification

• Product Name: 3M™ Liqui-Cel™ EXF-8x20 Industrial Series Membrane Contactor
• Membrane Type: XIND Fiber
• Membrane/Potting Material: Polypropylene / Epoxy
• Cartridge Configuration: Extra-Flow with Center Baffle
• Primary Application: CO₂ removal from liquid and other gas transfer applications

Operating limits

• Liquid Flow Guidelines: 1 – 11 m³/hr (5 – 50 gpm)
• Maximum Shellside LIQUID Working Temperature/Pressure:
  • 25°C, 4.8 barg (77°F, 70 psig)
  • 40°C, 2.1 barg (104°F, 30 psig)
  • Note: If no vacuum is used, 1.0 barg (15 psig) can be added to pressures above.
  • Note: If operating using air sweep, the liquid or air temperature should not exceed 30°C for any length of time. Exceeding 30°C will reduce contactor life.
• Maximum Applied Gas Pressure: 2.1 barg at 25°C (30 psig at 77°F) (for integrity testing at ambient temperatures; normal operating pressures are typically lower).
• Pressure Guideline: Liquid pressure should always exceed gas pressure.

Mechanical / hydraulic

• Nominal Dimensions:
  • Length: 663 mm (26.1 in)
  • Diameter: 219 mm (8.6 in)
  • Other dimension: 64 mm (2.5 in)
• Priming Volume (approximate):
  • Shellside: 6.7 L (1.8 gal)
  • Lumenside: 5.2 L (1.4 gal)
• Housing Material: PVC
• End Caps Material: Engineering thermoplastic
• Port Connections:
  • Shellside (Liquid Inlet/Outlet):

• Weight (approximate):
  • Dry: 13 kg (28 lbs)
  • Water-filled (shellside): 19 kg (43 lbs)
• Pressure Drop: Curves are provided in the source document for Water Flow Rate vs. Pressure Drop using water at 25°C, but specific numerical values are not listed in the text. See the official PDF for exact tabulated values.

Regulatory

• Complies with the limits as set by RoHS Directive 2011/65/EU Annex II; recasting 2002/95/EC.
