Isihlungi esingenamifanekiso siyisihlungi se-cylindrical sangaphandle sokuhlunga vacuum, kanye nomzimba we-cylinder yigumbi lonke le-vacuum, futhi umzimba wesilinda unegumbi elikhethekile lokubopha endaweni yokucaphuna. Umshini uqeda ikhanda lokusabalalisa, umphimbo kanye nenani elikhulu lemigqa ye-vacuum yesihlungi esijwayelekile, futhi uhlobo olusha lokuhlunga okuqhubekayo. Ihlanganiswa ikakhulukazi kwisilinda, idivaysi yokuvalwa uphawu, umgodi ongelona, i-stirrer, ithangi elimnandi nokunye. Isakhiwo nokuhlukaniswa kwendawo yomsebenzi kuboniswa esilinganisweni esingezansi. Lapho isihlungi singasebenzi, ingaphakathi lesilinda lingaphansi kwe-vacuum, ukuze ikhekhe lokuhlunga likhishwe ngaphezulu kwendwangu yokuhlunga, futhi i-filtrate kanye namanzi okugeza akhishwe ngokulandelana emikhawulweni emibili ye-ove shaft, Futhi ikhekhe lokuhlunga ligijimisa ngendwangu yokuhlunga. I-Deper Roller ikhishwe. Umshini awudingi ukushaya impahla futhi uhlanze indwangu yokuhlunga kwisilinda. Ngakho-ke, umsebenzi wedivayisi yokuvalwa uphawu ukubeka uphawu emgodini wokuhlunga engxenyeni yesilinda evezwa emoyeni (phakathi kwephuzu lapho indwangu yokuhlunga ithathwa endaweni yokubuyisa yendwangu yokuhlunga) ukuvikela i-vacuum ukuba ibe khona ephukile.
Enye into yesakhiwo sokuhlunga ukuthi ithangi lokuphakelayo lamukela isakhiwo esijulile sokukhulisa isikhathi sokukhulisa isikhathi sokuhlunga sokumunca ukwandisa umthamo wokukhiqiza. Ngejubane elifanayo, isikhathi sokucwilisa sokumunca se-GDU-40 Uhlobo olungelonakalisi lweBelt Belt luyi-1/3 kuya ku-2/3 ngaphezulu kwesihlungi se-General Everternal Type Villuum Vacuum.
