What is a Membrane Nitrogen Generation System?

Membrane Nitrogen Generators use a hollow fiber filter to separate oxygen from Nitrogen.

As atmospheric air is compressed by an air compressor and pushed through a hollow fiber membrane, a portion of the air (mainly oxygen) is filtered out, leaving behind a purified nitrogen gas; this is how a membrane nitrogen generator works. 

Industrial nitrogen generating systems will filter the gas through more stages before it reaches the membrane, removing more of the other gas constituents like moisture and dirt. Fine mesh filters are frequently utilized in the nitrogen production process to remove airborne particles and moisture from the air. These additional filtration steps will provide improved nitrogen purity and safeguard the membrane. Even with the added filtration, Membranes have a shorter life expectancy compared to a PSA. The typical operating life of a membrane nitrogen generator is 5 to 7 years.
