  • Shellside (Liquid Inlet/Outlet): 2 inch sanitary
  • Lumenside: 2 inch sanitary
• Seal Options
  • Material: EPDM
  • Applications: All Purpose
• Priming Volume (approximate)
  • Shellside: 6.3 L (1.7 gal)
  • Lumenside: 9.5 L (2.5 gal)

Operating limits

• Liquid Flow Guidelines: 1 – 11 m³/hr (5 – 50 gpm)
• Maximum Shellside LIQUID Working Temperature/Pressure
  • 25°C (77°F), 9.3 barg (135 psig)
  • 50°C (122°F), 3.1 barg (45 psig)
  • 70°C (158°F), 1.1 barg (15 psig)
  • If no vacuum is used, 1.0 barg (15 psig) can be added to pressures above.
• Maximum Applied Gas Pressure: 5.2 barg at 25°C (75 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 temperature/pressure limits for housings and membrane.

Applications

• Recommended for O₂ and CO₂ removal from liquids, carbonation, and other gas transfer applications.

Regulatory

• Complies with the limits as set by RoHS Directive 2011/65/EU Annex II; recasting 2002/95/EC.
• Constructed of FDA CFR title 21 compliant materials for wetted parts only.

Performance Characteristics

• Curves are provided for O₂ removal, CO₂ removal, and pressure drop versus water flow rate. Test conditions for O₂ removal involved N₂-vacuum combo mode with water at 20°C, vacuum at 50 mm Hg absolute, and N₂ sweep at 0.25 scfm. Test conditions for CO₂ removal involved air sweep mode with water at 25°C and air sweep at 10 scfm.
• See the official PDF for exact tabulated values and detailed performance curves.
