I-VPSA i-Oxygen Generator yi-adsorption ye-pressurized kunye ne-vacuum extraction generator. Umoya ungena kwibhedi ye-adsorption emva koxinzelelo. Isihluzo esikhethekileyo semolekyuli sikhetha ngokukhetha initrogen, ikharbon diokside kunye namanzi ukusuka emoyeni. I-molecular sieve ihlanjululwa phantsi kweemeko ze-vacuum, i-recycling i-oksijini ecocekileyo (90-93%). I-VPSA inokusetyenziswa kwamandla aphantsi, eyancipha ngokunyuka kwesityalo.
I-Shanghai LifenGas i-VPSA i-oxygen generators ifumaneka kwiimodeli ezininzi. Ijenereyitha enye inokuvelisa i-100-10,000 Nm³/h yeoksijini enobunyulu obungama-80-93%. I-Shanghai LifenGas inamava amaninzi ekuyilweni nasekuveliseni iikholomu ze-adsorption ze-radial, ezibonelela ngesiseko esiluqilima sezityalo ezinkulu.
