Izvo zvinoshandiswa kusefa zvinhu zvine mineral fiber, yakasikwa faibha kana synthetic fiber, sefa zvinhu fiber yakakamurwa kuita mhando shanu dzekusefa kwechinhu chemukati mumhepo, vanogona kuita basa rakazara.

Sedimentation: iyo yakakura particle zvinhu mumhepo inoyerera inokonzerwa negiravhiti sedimentation kune iyo sefa zvinhu, yakaparadzaniswa kubva kumhepo;

Inertia kukanganisa: kana zvimedu zviri mumhepo inofefetera bypass block pamberi pesefa zvinhu fiber, iyo yepamusoro mhando yezvimedu inotsauka kubva kugwara rekuyerera kwemhepo neinertia, inorova iyo sefa zvinhu fiber inosefa pasi;

Kupinda: zvimedu zviri mumhepo inoyerera zviri padyo nekuyerera kweiyo sefa zvinhu, nekuti radius yechikamu yakakura kupfuura chinhambwe chiri pakati peiyo streamline uye iyo sefa zvinhu "yakakweshwa" uye inobatwa neiyo sefa zvinhu;

Diffusion mhedzisiro: yakakanganiswa nekufamba kwekupisa kwemamorekuru emhepo, zvidimbu zvidiki zvakanyanya nekukanganisa kwemamorekuru emhepo, anogara achichinja nzira yekufamba, Brownian motion, kungosangana nesefa fiber inosefa pasi;

Electrostatic effect: kana iyo sefa zvinhu fiber ine isina simba static magetsi, zvisinei nekuti zvimedu zviri mumhepo inoyerera pachayo ine static magetsi, kana iri padhuze nesefa zvinhu fiber zviri nyore kukwezvwa nemagetsi akamira uye kusefa pasi, electrostatic effect inogona. batsira mafirita zvinhu kunatsiridza kusefa kushanda zvakanaka pasina kuwedzera kuyerera kwemhepo
