Chotolera fumbi chamkuntho chapangidwa kuti chiyeretse mpweya kapena zakumwa kuchokera ku tinthu tating'onoting'ono.Mfundo yoyeretsa ndi inertial (pogwiritsa ntchito mphamvu yapakati) komanso yokoka.Otolera fumbi la Cyclone ndiye gulu lalikulu kwambiri pakati pa zida zonse zosonkhanitsira fumbi ndipo amagwiritsidwa ntchito m'mafakitale onse.
Wotolera fumbi la mvula yamkuntho amapangidwa ndi chitoliro cholowetsa, chitoliro chotulutsa mpweya, silinda, chulucho ndi phulusa.
Mfundo ya chimphepo chotsutsana ndi madzi ndi motere: mtsinje wa mpweya wafumbi umalowetsedwa m'zida kudzera mu chitoliro cholowera kumtunda.Kuthamanga kwa gasi kumapangidwa mu chipangizocho, kulunjika kumunsi kwa gawo la chipangizocho.Chifukwa cha mphamvu inertial (centrifugal mphamvu), fumbi particles ikuchitika mu mtsinje ndi kukhazikika pa makoma a zipangizo, ndiye anagwidwa ndi yachiwiri mtsinje ndi kulowa m'munsi, kudzera kubwereketsa mu nkhokwe zosonkhanitsira fumbi.Mtsinje wa gasi wopanda fumbi ndiye umasunthira mmwamba ndikutuluka mumkuntho kudzera papaipi ya coaxial exhaust.
Chimalumikizidwa ndi potulutsa mpweya wa chowumitsira chowumitsira kumapeto kudzera pa payipi, komanso ndi chida choyamba chochotsera fumbi cha gasi wotentha mkati mwa chowumitsira.Pali mitundu yosiyanasiyana monga chimphepo chamkuntho ndi gulu la chimphepo chambiri chomwe chingasankhidwe.
