Chikwama cha fyuluta ndi mtima wa fyuluta yachikwama panthawi yogwira ntchito. Nthawi zambiri, thumba la cylindrical pulse filter thumba limayimitsidwa molunjika mu chotolera fumbi. Fumbi-lomwe lili ndi gasi limalowa m'chotolera fumbi kuchokera kumalo olowera mpweya, kumadutsa m'mbale yolondolera phulusa, ndipo tinthu tambirimbiri ta fumbi mu gasiyo timasiyanitsidwa ndi inertia ndikugwera molunjika mu chopondera phulusa. Fumbi-lomwe lili ndi gasi limalowa mugawo losefera la thumba lazosefera la bokosilo. Fumbi lochuluka limagwidwa kunja kwa thumba la fyuluta, ndipo mpweya woyera umalowa mu thumba la fyuluta kudzera muzosefera. Mpweya woyeretsedwa umalowa m'bokosi lapamwamba kudzera pa doko la thumba la fyuluta ndikutulutsidwa kuchokera ku mpweya. Khola mkati mwa thumba la fyuluta limagwiritsidwa ntchito kuthandizira thumba la fyuluta kuti thumba la fyuluta lisagwe. Panthawi imodzimodziyo, zimathandiza kuchotsa ndi kugawanso keke yafumbi.
