Revolutionizing Fluid Degassing Technology

The 3M™ Liqui-Cel™ G681W 1×3 membrane contactor represents the pinnacle of degassing innovation, engineered to deliver unparalleled performance in removing dissolved gases from critical fluids. Utilizing 3M’s proprietary membrane fiber technology, this industrial-grade degassing module transforms how industries manage fluid purity, system protection, and process optimization across countless applications.

Engineered Excellence: Core Technology & Specifications

Featuring 3M’s patented polypropylene hollow fiber membrane with hydrophobic microstructure, the G681W 1×3 module provides exceptional gas transfer efficiency in a compact 1-inch diameter by 3-inch length configuration. This membrane contactor operates on the principle of partial pressure differential, allowing dissolved gases (O₂, CO₂, N₂) to permeate through microporous membranes while preventing liquid penetration. The module’s optimized fiber packing density and flow path design maximize gas removal efficiency while minimizing pressure drop.

Critical Industrial Applications

Performance Advantages in Critical Applications

Compared to traditional vacuum degassing or sparging methods, the 3M G681W 1×3 offers substantial benefits:

• Superior Efficiency: Removes up to 99.9% of dissolved gases in single pass
• Consistent Performance: Maintains stable degassing regardless of flow rate fluctuations
• Chemical Compatibility: Resists a wide range of aqueous solutions and organic solvents
• Zero Contamination: Non-fiber releasing construction prevents downstream contamination
• Energy Efficient: Operates at ambient temperature without heating requirements
• Compact Design: High surface-area-to-volume ratio saves valuable system space

Installation & Maintenance Considerations

The modular cartridge design enables straightforward installation into standard 1-inch housings with simple O-ring seals. Routine maintenance involves periodic integrity testing and cleaning with compatible solutions (NaOH, HCl, or specialty cleaners). The hydrophobic membrane naturally resists fouling, while the robust polypropylene construction withstands repeated cleaning cycles. Standard operating conditions recommend inlet pressures below 45 psi (3.1 bar) and temperatures up to 60°C (140°F) for optimal performance and membrane longevity.
