What is membrane nitrogen technology and how does it work?

A membrane nitrogen generator makes this separation happen with a membrane that consists of thousands of hollow polymer fibers. These fibers have a unique structure that allows only the oxygen and any remaining water vapors in the air to escape through its walls. This process is called “ permeation ”. Once outside the fibers, the O₂ is ...
