Isihluzi sechungechunge se-SRFA senziwe ngeefilter ezimbini ezizodwa, i-2-position 3 -way directioal valve, by-pass valve, indicator and diffuser. Ilula kubume kwaye kulula ukuyisebenzisa. Ikhwele phezulu kwitanki; kukho i-valve yokupasa kunye nesalathi esingcolisayo kuyo, ukukhusela inkqubo yokhuseleko lwamanzi. Inqaku leli cebo lokucoca livumela ukusebenza okuqhubekekayo nangexesha lokutshintsha into, evalwe ngengcoliseko. Xa isihluzi sivalekile ngokungcolisayo nesiphumo soxinzelelo sifikelela kwi-0.35MPa isibonisi siya kunika imiqondiso. Ngeli xesha, jika i-inorder ye-inal ye-inorder yokwenza enye ifilterwork uze utshintshe into.
