I-laminar flow hood sisixhobo esikhusela umqhubi kwimveliso. Injongo yaso ephambili kukuphepha ukungcola kwemveliso. Umgaqo osebenzayo wesi sixhobo usekelwe ekuhambeni komoya we-laminar. Ngesixhobo esithile sokucoca, umoya uhamba ngokuthe tye ngesantya esithile ukuze wenze umoya ohlayo. Lo moya unesantya esifanayo kunye necala elifanayo, elinokuphelisa ngempumelelo amasuntswana kunye neentsholongwane emoyeni.
I-laminar flow hood idla ngokuba nomthombo womoya ophezulu kunye nenkqubo yokukhupha umoya esezantsi. Inkqubo yokubonelela umoya itsala umoya ngefeni, iwuhluze nge-hepa air filter, ize emva koko iwuthumele kwi-laminar flow hood. Kwi-laminar flow hood, inkqubo yokubonelela umoya icwangciswe ezantsi ngokusebenzisa izithuba zokubonelela umoya ezenzelwe ngokukodwa, okwenza umoya ube kwimeko efanayo yokuhamba komoya. Inkqubo yokukhupha umoya esezantsi ikhupha ungcoliseko kunye nezinto ezincinci kwi-hood nge-outlet yomoya ukugcina ingaphakathi le-hood licocekile.
I-laminar flow hood sisixhobo sokubonelela ngomoya ococekileyo sendawo esinokuhamba ngokuthe nkqo kwicala elinye. Ukucoceka komoya kwindawo yasekuhlaleni kunokufikelela kwi-ISO 5 (udidi lwe-100) okanye ngaphezulu kwindawo ecocekileyo. Inqanaba lokucoceka lixhomekeke ekusebenzeni kwesihluzo se-hepa. Ngokwesakhiwo, ii-laminar flow hood zahlulwe zaba yifeni kunye nefeni, uhlobo lomoya obuya ngaphambili kunye nohlobo lomoya obuya ngasemva; ngokwendlela yokufakela, zahlulwe zaba luhlobo oluthe nkqo (lwekholamu) kunye nohlobo lokuphakamisa. Izinto zayo ezisisiseko ziquka igobolondo, isihluzo sangaphambi, ifeni, isihluzo se-hepa, ibhokisi yoxinzelelo engashukumiyo kunye nezixhobo zombane ezixhasayo, izixhobo zolawulo oluzenzekelayo, njl. Ukungena komoya kwe-unidirectional flow hood enefeni ngokubanzi kuthathwa kwigumbi elicocekileyo, okanye kunokuthatyathwa kwi-mezzanine yobugcisa, kodwa ulwakhiwo lwayo lwahlukile, ngoko ke kufuneka kuqwalaselwe uyilo. I-laminar flow hood engenafeni yenziwe ikakhulu sisihluzo se-hepa kunye nebhokisi, kwaye umoya wayo ongenayo uthathwa kwinkqubo yokucoca umoya opholileyo.
Ukongeza, i-laminar flow hood ayidlali nje indima ephambili yokuphepha ungcoliseko lwemveliso, kodwa ikwahlukanisa indawo yokusebenza kwindalo engaphandle, ithintele abaqhubi ekuhlaselweni zizinto ezingcolisayo zangaphandle, kwaye ikhusela ukhuseleko nempilo yabasebenzi. Kwezinye iimvavanyo ezineemfuno eziphezulu kakhulu kwindawo yokusebenza, inokubonelela ngendawo yokusebenza ecocekileyo ukuthintela iintsholongwane zangaphandle ekuchaphazeleni iziphumo zovavanyo. Kwangaxeshanye, ii-laminar flow hood zihlala zisebenzisa izihluzi ze-hepa kunye nezixhobo zokulungisa ukuhamba komoya ngaphakathi, ezinokubonelela ngobushushu obuzinzileyo, ukufuma kunye nesantya sokuhamba komoya ukugcina imeko-bume engaguqukiyo kwindawo yokusebenza.
Ngokubanzi, i-laminar flow hood sisixhobo esisebenzisa umgaqo wokuhamba komoya we-laminar ukucubungula umoya ngesixhobo sesihluzo ukugcina okusingqongileyo kucocekile. Ineendlela ezahlukeneyo zokusetyenziswa kwiindawo ezininzi, ibonelela ngendawo yokusebenza ekhuselekileyo necocekileyo kubasebenzi kunye neemveliso.
