Isa yakakwirira inoshanda sefa mukamuri yekushandisa kudzivirira guruva kushanda:

Kuiswa kwemafirita emhepo akanyanya kushanda zvakanakamuimba yekuvhiya inofanira kuenderana nezvinodiwa zvinotevera:

1. Mushure mekuonekwa kwekuongorora kweHEPA sefamuimba yekushanda inokodzera, inofanira kuiswa pakarepo;

2 Kuiswa kweHEPA sefa firimu kunofanirwa kuve kwakatsetseka, kwakachena, kupfava kwega rega kusefa yekumisikidza furemu kutsauka, hakufanire kudarika 1 ~ 2㎜;

3 Iyo dhizaini yekumisikidza sefa inofanirwa kuve yakarurama, mushure mekuiswa kwesefa yakatenderedza uye interface, inofanirwa kuve yakasimba uye isina kubuda;

4 HEPA sefa uchishandisa mechaniki chisimbiso, inofanirwa kushandisa isina mhepo padhi chisimbiso, ukobvu hwayo i6 ~ 8㎜, uye padyo nefirimu furemu;Mushure mekugadzwa, kudzvanywa kwepadhi kunofanirwa kuve yunifomu, uye iyocompression rate ndeye 25 ~ 50%;Skena yekuona kuvuza mushure mekuisa;

5 Panguva iyoHEPA sefainotora hydraulic seal, iyo groove furemu inoiswa yakatwasuka, uye hapazove nekudonha chiitiko;Hamuna tsvina kana mwando mutangi.Kureba kwemvura yekuvharisa mutangi kunofanirwa kuve 2/3 yehudzamu hwetangi, uye nzvimbo yekunyunguduka yemvura yekuvharisa inofanira kunge yakakwira kupfuura 50 ℃.
