Ntchito Yaikulu: Tebulo Loyeretsa Mpweya Malemba a Buku: Venpur ndi tebulo lomwe limayeretsa ndi kutsuka mpweya m'malo apagulu monga makafe ndi malo odyera. Venpur imagwiritsa ntchito kuwala kwa ultraviolet ndi ukadaunifi wowonjezera okosijeni kuti apange kupanikizika kwakukulu (negative pressure) mozungulira tebulo, kotero mpweya wozungulira umasefedwa ndi kutsukidwa. Fani yowonjezera okosijeni imawonjezera liwiro la kuyenda kwa mpweya, ndipo nyali ya ultraviolet imayikidwa kuti ikhudzane bwino ndi mpweya wamayendedwe. Sefa ya waya pa khomo lolowera mpweya imateteza zinthu zachilendo kulowa. Chowunikira cha infrared chimayambitsa ntchito yoyeretsa pamene wogwiritsa ntchito ayandikira, ndipo chimayimitsa pamene wogwiritsa ntchitoyo achoka. Chophimba chapamwamba chimatha kuchotsedwa kuti pakhale kusamalira sefa (filter maintenance).
