Membrane Working Principle

The membranes are formed into hollow fibres to obtain maximum membrane surface/unit of volume. Thousands of fibres are bundled into a casing that projects them, routes the gas properly from feed to product end, and creates handy and standardized units that can easily be stacked together for modular capacity increase of the system.

Atmospheric air is compressed, filtered, heated and fed to the bore size of the membranes.


As the air flows inside the individual fibres, the O2, CO2, H2O in the air permeate faster than nitrogen through the membrane walls to the low-pressure side of the fibres.

Benefits of Air Products’ Nitrogen N2 Membrane System:

1. Unparalleled total lifetime

2. Particle, liquid water and oil vapor tolerant membrane

3. Marine-proven membranes for over 25 years.

4. Guaranteed lifetime after sales’ services worldwide

5. Automatic N2 purity control
