EXF Series 8 x 40

Summary

Product Identification

• Product Name: 3M™ Liqui-Cel™ EXF-8x40 Series Membrane Contactor
• Membrane Type: X40 Fiber
• Cartridge Configuration: Extra-Flow with Center Baffle
• Recommended Use: High pressure O₂ removal and other gas transfer applications

Mechanical / Hydraulic

• Housing Material: Fiber Reinforced Plastic (FRP)
  • FRP Vessel Code-rated to ASME BPVC Section X
• Connections:
  • Shellside (Liquid Inlet/Outlet): 1.5 Inch Grooved pipe fitting
  • Lumenside: 1.5 Inch Grooved pipe fitting
• Seal Options Material: EPDM (All Purpose)
• Dimensions (Nominal):
  • Length: 1502 mm (59.2 in)
  • Diameter: 255 mm (10.0 in)
  • Other dimensions: 212 mm (8.3 in), 1194 mm (47.0 in)
• Weight (Approximate):
  • Dry: 35 kg (78 lbs)
  • Water-filled (shellside): 50 kg (110 lbs)

Operating Limits

• Maximum Shellside LIQUID Working Temperature/Pressure:
  • 5-25°C, 19.7 barg (41-86°F, 285 psig)
  • 60°C, 12.0 barg (140°F, 175 psig)
  • 85°C, 1 barg (185°F, 15 psig)
  • If no vacuum is used, 1.0 barg (15 psig) can be added to pressures above.
• Maximum Applied Gas Pressure: 2.1 barg at 25°C (30 psig at 77°F)
  • Maximum applied gas pressure is for integrity testing at ambient temperatures. Normal operating pressures are typically lower.
• Note: Liquid pressure should always exceed gas pressure. See Operating Guide for complete temp/pressure limits for housings and membrane.

Liquid Flow Guidelines

• Liquid Flow Rate: 7 – 28 m³/hr (30 – 125 gpm)

Membrane Characteristics

• Membrane/Potting Material: Polypropylene / Epoxy

Priming Volume (Approximate)

• Shellside: 15.4 L (4.1 gal)
• Lumenside: 13.6 L (3.6 gal)

Performance Curves

The document includes graphs illustrating the percentage of dissolved oxygen removal and pressure drop as functions of water flow rate. These curves represent nominal values for an FRP housing using water at 20ºC, under N₂-vacuum combo mode (vacuum: 50 mm Hg, N₂ sweep: 0.5 SCFM). Characteristics may vary under different operating conditions. 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.
