Medical mpweya jenereta ndi kuthamanga swing adsorption (PSA) luso monga maziko, kuchotsa mpweya mu mpweya wa zida zatsopano, ntchito molecular sieve thupi adsorption ndi desorption njira mu molecular sieve mpweya jenereta potsegula, pamene kuthamanga mu mlengalenga. akhoza kukhala nayitrogeni adsorption, otsala unabsorbed mpweya amasonkhanitsidwa, kukhala ndicho pambuyo kuyeretsedwa mankhwala a mkulu chiyero mpweya.Njira yeniyeni yogwirira ntchito ndikuti mpweya woponderezedwa umatsukidwa ndi chowumitsira mpweya ndikulowa munsanja ya adsorption kudzera mu valve yosinthira.Mu adsorption nsanja, nayitrogeni ndi adsorbed ndi maselo sieve, mpweya anaunjikana pamwamba pa nsanja adsorption mu thanki yosungirako mpweya, ndiyeno mwa kuchotsa fungo kuchotsa fumbi kuchotsa fyuluta ndi yotseketsa fyuluta fyuluta ndi oyenerera mankhwala okosijeni.Zigawo zikuluzikulu ndi: thanki mpweya, mpweya kompresa, ozizira kuyanika makina, mpweya mpweya, thanki mpweya ndi zina zotero.
