Izicelo
Iyunithi yesihluzi sefeni ye-FFU, ngamanye amaxesha ebizwa ngokuba yi-laminar flow hood, inokudityaniswa kwaye isetyenziswe ngendlela yemodyuli kwaye isetyenziswa kakhulu kwigumbi elicocekileyo, ibhentshi yokusebenzela ecocekileyo, imigca yemveliso ecocekileyo, igumbi elicocekileyo elihlanganisiweyo kunye negumbi elicocekileyo le-laminar flow.
Iyunithi yesihluzo sefeni ye-FFU ixhotyiswe ngezihluzo eziphambili kunye ne-hepa ezinezigaba ezimbini. Ifeni ifunxa umoya ukusuka phezulu kweyunithi yesihluzo sefeni kwaye iyihluze ngokusebenzisa izihluzo eziphambili kunye ne-hepa.
Iingenelo
1. Ilungele ngokukodwa ukuhlanganiswa kwimigca yemveliso ecocekileyo kakhulu. Ingalungiswa njengeyunithi enye ngokweemfuno zenkqubo, okanye iiyunithi ezininzi zingadityaniswa ngochungechunge ukwenza umgca wokuhlanganisa igumbi elicocekileyo leklasi ye-100.
2. Iyunithi yesihluzi sefeni ye-FFU isebenzisa ifeni yangaphandle ye-rotor centrifugal, eneempawu zobomi obude, ingxolo ephantsi, ayigcinwa ikwimeko entle, ingcangcazela encinci, kunye nokulungiswa kwesantya okungenamagxa. Ifanelekile ukufumana umgangatho ophezulu wendawo ecocekileyo kwiindawo ezahlukeneyo. Ibonelela ngomoya ococekileyo osemgangathweni ophezulu kwigumbi elicocekileyo kunye nendawo encinci yeendawo ezahlukeneyo kunye namanqanaba ahlukeneyo okucoceka. Ekwakhiweni kwegumbi elitsha elicocekileyo, okanye ukuhlaziywa kwegumbi elicocekileyo, ayinakuphucula kuphela inqanaba lokucoceka, inciphise ingxolo kunye nokungcangcazela, kodwa ikwanciphisa kakhulu iindleko. Kulula ukuyifaka nokuyigcina, yinxalenye efanelekileyo yeendawo ezicocekileyo.
3. Ulwakhiwo lweqokobhe lwenziwe ngepleyiti ye-aluminium-zinc ekumgangatho ophezulu, ekhaphukhaphu ngobunzima, enganyangekiyo kukugqwala, enganyangekiyo kukugqwala, kwaye intle.
4. Ii-FFU laminar flow hood ziyaskenwa kwaye zivavanyelwe nganye nganye ngokwe-US Federal Standard 209E kunye ne-dust particle counter ukuqinisekisa umgangatho.
