Ogwiritsa ntchito pampu ya vacuum sayenera kukhala osadziwa kuopsa kwa ufa. Pampu ya vacuum ngati chida cholondola chimakhudzidwa kwambiri ndi ufa. Ufa ukalowa mu pampu ya vacuum panthawi yogwira ntchito, umayambitsa kung'ambika kwa mpope. Chifukwa chake mapampu ambiri a vacuum amakhazikitsazosefera zolowerakusefa ufa.
Komabe, kuchuluka kwa ufa kukakhala kwakukulu, kusefa kumakhala vuto lovuta. Kuthekera kwa kusefa kwa katiriji yosefera ndikochepa, makamaka makatiriji ena omwe amapezeka pamsika. Sangathe kuthana ndi vutolo. Mwina kumayambiriro kwa ntchito, zonse zimayenda bwino. Koma pakangopita nthawi yochepa, mupeza kuti chosefera chatsekedwa, ndikuchepetsa kuthamanga kwa kupopera. Zitha kupangitsa kuti pampu ya vacuum iyimitsidwe. Choyipa kwambiri ndikuti ufa umalowa mu vacuum pump ndikuwononga monga tafotokozera pamwambapa.
Yankho losavuta ndikulowetsa chinthu chosefera. Koma ndiyonso njira yovuta kwambiri chifukwa chofuna kusintha pafupipafupi. Komanso, mtengo wake ndi wokwera kwambiri. Mutha kusinthanso fyuluta yonse.Blowback fyulutazimawonekera momwe nthawi zimafunikira kuti athetse vutoli moyenera.
Poyerekeza ndi zinthu wamba zosefera, kusiyana kwakukulu kwa fyuluta ya blowback ndikuwonjezera kwa doko la blowback pa doko lake lopopera ndi kukhetsa pansi pake. Pazikhalidwe zogwirira ntchito, gasi amalowa kuchokera kumalo olowera, amadutsa muzosefera, kenako amatuluka kuchokera padoko lotulutsa. Pamene vacuum mpope alowa mu mode standby kapena kutseka pansi, tikhoza kuyeretsa fyuluta chinthu mkati mwa kuwomba mmbuyo - mpweya adzalowa mkati fyuluta chinthu kuchokera blowback doko, kuwomba ufa pamwamba pa fyuluta chinthu mpaka kuda.
Ponseponse, zosefera wamba sizilimba pansi pamikhalidwe yokhala ndi ufa wambiri, ndipo zosefera za blowback zimakhala ndi moyo wautali ndipo ndizosavuta kuziyeretsa. Chifukwa chake, ngakhalezosefera za blowbackndizokwera mtengo, zimakhala zotsika mtengo pakapita nthawi.
