Isihlungi se-HEPA siyisihlungi esikhulu esisetshenziswa kuzihlanzi zomoya eziningi. Isetshenziswa kakhulu ukuhlunga uthuli lwezinhlayiya ezincane zamangqamuzana nezinto eziqinile ezimisiwe ezinobubanzi obungaphezu kuka-0.3μm. Igebe lentengo lezihlungi ze-HEPA emakethe likhulu kakhulu. Ngaphezu kwezici zentengo zemikhiqizo ngokwayo, kunobudlelwano obuthile nezihlungi ze-HEPA.
Izihlungi ze-HEPA nokunye okunjalo kuhlukaniswe kwaba yi-G1-G4, F5-F9, H10-H14 kanye ne-U15-U17 ngokwesilinganiso samanje sase-Europe. Uhlobo oluvame kakhulu lwesihlanzi somoya yibanga H, okuyisihlungi esisebenza kahle noma esingasebenzi kahle. I-H13 yaziwa njengesihlungi esihle kakhulu se-H13-14. Isihlungi se-HEPA sebanga le-H13 singafinyelela ukusebenza kahle okuphelele kwama-99.95%. Ukusebenza kahle okuphelele kwesihlungi se-H14 grade HEPA singafinyelela ku-99.995%.
Kunjalo, izinga eliphezulu lokucwenga lesihlungi se-HEPA ngokwezinga lase-Europe yi-U grade, futhi isihlungi se-HEPA esingcono kakhulu se-U-17 sinomsebenzi ophelele wokuhlanza ongu-99.999997%. Nokho, ngenxa yokuthi isihlungi se-U-grade HEPA siyabiza ukusikhiqiza, sidingeka kakhulu endaweni yokukhiqiza. Ngakho-ke azikho izicelo eziningi emakethe.
Ngaphezu kwebanga lokuhlanza, isihlungi se-HEPA sinesilinganiso somlilo. Imakethe iyihlukanisa ibe amabanga amathathu ngokwezinga layo lokumelana nomlilo: i-HEPA mesh eyinhloko, zonke izinto zokwakha ze-HEPA mesh azishi, futhi izinto ezingashi kufanele zihambisane ne-GB8624- 1997 Ikilasi A; inethiwekhi yesibili ye-HEPA, i-HEPA mesh filter material kufanele ingahambisani ne-GB8624-1997 Ikilasi A izinto ezingashi, ipuleti lokuhlukanisa, ifreyimu ingasetshenziswa ngokuhambisana ne-GB8624-1997 B2 yekilasi lezinto ezivuthayo. Kunethiwekhi ye-HEPA enamazinga amathathu, zonke izinto zenethiwekhi ye-HEPA zingasetshenziswa ngokuhambisana nezinto zebanga le-GB8624-1997 B3.
Ngaphezu kwamabanga, izihlungi ze-HEPA ziza ngezinto ezihlukene. Izinto ezivame kakhulu ziyizinhlobo ezinhlanu: Iphepha lokuhlunga le-PP, iphepha lokuhlunga le-PET eliyinhlanganisela, indwangu encibilikisiwe ye-polyester engalukiwe kanye ne-meltblown glass fiber. Izinhlobo ezinhlanu ezihlukene zamanethiwekhi okuhlunga e-HEPA anezinzuzo zawo kanye nokubi, futhi izinkambu eziyinhloko zohlelo nazo zihlukile. Isihlungi se-HEPA sephepha lesihlungi se-PP sisetshenziswa kakhulu kwizihlanzi zomoya ngenxa yokumelana ne-asidi ne-alkali, ukumelana nokugqwala, indawo ephezulu yokuncibilika, ukusebenza okuzinzile, ukungabi nabuthi, ukungabi naphunga, ukusatshalaliswa okufanayo, ukumelana okuphansi, ukusebenza kahle okuphezulu nokuvikelwa kwemvelo.
Okokugcina, ake sikhulume ngesihlungi se-HEPA semeshi esihlanza umoya - isihlungi esiyinhlanganisela se-HEPA esakhiwe ukotini okuhlunga uthuli lwe-HEPA ngegobolondo likakhukhunathi ocushiwe kanye nenhlanganisela ye-carbon fibre ecushiwe. Ukuhlanzwa komoya kusetshenziswa lolu hlobo lwesihlungi Idivayisi ingcono kunesihlanzi somoya se-HEPA ngokohlobo lokuhlanza nokusebenza kahle kokuhlanza. Ngakho-ke, abathengi abaningi ngokwengeziwe sebeqalile ukushiya isihlungi se-HEPA futhi esikhundleni salokho bakhetha isihlungi somoya esiyinhlanganisela.
