Nitrogen Membrane Technology

How is Nitrogen Generated from the Parker Membranes?
A reliable, high performance membrane module is the heart of a nitrogen gas generator. Customers around the world trust Parker Hannifin to provide reliable nitrogen gas generators that meet the specific needs of our customer applications.

Pressurized air is fed to one end of the hollow fiber membranes. The permeation rates of water vapor, CO2, and oxygen contained in the air stream are faster than nitrogen and argon and will rapidly diffuse through the fiber walls. The slower diffused nitrogen molecules remain in the fiber bore and are collected as the nitrogen product gas. The air flow rate will determine how much undiffused oxygen remains with the nitrogen gas. The nitrogen product gas is extremely dry, with atmospheric dew points typically below -40°F. The membranes act like a filter with no moving parts and continuously generate nitrogen at selected flow and purity.

Why are Parker HiFluxx® Membranes Unique from other Membrane Filters?
Simply stated, Parker HiFluxx® membranes are the most permeable membranes in the world! High permeability means more nitrogen is produced in each fiber.
 

  • Fewer membranes are required, resulting in lower membrane investment and smaller membrane footprints vs. competitive systems.
     
  • Excellent nitrogen production, even at low pressures, allows Parker membranes to operate directly from instrument or utility air systems or low pressure industrial compressors and still be compact and lightweight.
     
  • Low pressure compressors operate with less energy, less noise, and less maintenance.
     
  • Parker fibers are robust and are less sensitive to particle contamination than competitors.
     
  • No additional heating is required to improve membrane nitrogen production rates.
     
  • N2 production is extremely stable over time with little or no performance degradation.
