Hangaia hauora hauora me te hangarau piu piu (PSA) hei turanga, ki te tango i te hāora mai i te hau o nga taputapu hou, te whakamahi i te molecular sieve physical adsorption me te desorption technique i roto i te molecular sieve oxygen generator i roto i te utaina, ina te pehanga i te rangi. ka taea te hauota adsorption, kohia te toenga hāora unabsorbed te, riro ara i muri i purenga maimoatanga o te hāora parakore tiketike.Ko te mahinga mahi motuhake ko te hau kua oti te purea e te whakamaroke horoi o te hau ka uru atu ki te pourewa adsorption na roto i te paera whakawhiti.I roto i te pourewa adsorption, hauota te adsorbed e tatari rāpoi, putu hāora te i runga i te tihi o te pourewa adsorption ki te tank rokiroki hāora, a ka i roto i te tango kakara, tātari tango puehu me sterilization tātari tātari he tohu hauora hauora.Ko nga waahanga matua ko: tank hau, hau compressor, miihini whakamaroke makariri, ope hāora, tank hāora me etahi atu.
