GMAG Stands for Mobile Gaseous Nitrogen Generating System
You don't need liquid nitrogen any longer to obtain very pure high-pressure nitrogen.

Thanks to our standalone generator designed on the basis of polymer fiber membranes, we can supply nitrogen from an easily-handled device supplied with ambient air and consuming very little electric power.
This generator is far more flexible and autonomous than storage systems, which makes it interesting for air forces and airport companies who need to inflate tires, manage aircraft shock absorbers and ensure refilling of missile capacities, etc
