Nitrogen generator o se masini gaosiga o le nitrogen ua fuafuaina ma gaosia e tusa ai ma le tekonolosi PSA. E fa'aogaina e le fa'atupu nitrogen le sieve mole mole kaponi (CMS) e fai ma fa'asu'i. E masani ona faʻaoga lua faʻamaʻi olo tutusa, pulea le inlet pneumatic valve e otometi lava ona faagaoioia e le inlet PLC, alternately pressurized adsorption ma decompressing regeneration, atoatoa nitrogen ma le okesene vavaeeseina, e maua ai le maualuga mama mama nitrogen.
O mea mata o le carbon molecular sieve o phenolic resin, pulverized muamua ma tuʻufaʻatasia ma mea faavae, ona faʻagaoioia pores. Tekinolosi PSA vavaeeseina nitrogen ma le okesene e le van der Waals malosi o carbon molecular sieve, o le mea lea, o le tele o le vaega i luga, o le sili atu toniga le tufatufaina pu, ma le tele o le numera o pores po o subpores, o le adsorption gafatia e tele.
