Gas separation with membrane uses the principle of selective gas permeation for
the membrane.
Membrane type-nitrogen generator uses a hollow-fiber type gas separation
membrane that has the property of permeating oxygen more easily than nitrogen.
In other words, when compressed air flows into the polyimide hollow-fiber
membrane, nitrogen, which is relatively slowly permeated through the high
pressure side (inside the hollow-fiber), passing through the wall (membrane) of
the hollow-fiber, and oxygen is passing through the low pressure side (outside
the hollow fiber) then permeated and released into the atmosphere.

PSA(Pressure Swing Adsortion) Type
Pressure Swing Adsorption (PSA) technology refers to a technology that separates
a gas from the air using the difference in the adsorption power of the crystal
gas of Molecular Sieve.
In other words, adsorption is defined as binding gas molecules to an absorbent
which is a solid material through molecule absorption.
The PSA device separates gas mixtures using the difference of the adsorption
power for gases exerted by various adsorbents in the form of individual or
compound types.
Compressed air passes through the Molecular Sieve layer of crystal structure
with micro perforation in the gas separation process, and the gas is to be
adsorbed by the adsorbent, and separated passes freely through this layer.
PSA nitrogen generator applies dehumidified compressed air into two or more
adsorption towers that are filled with an adsorbent called CMS (Carbon Molecular
Sieve) and repeatedly performs the pressurization-> adsorption-> decompression->
purge steps to continuously generate high-purity nitrogen.
