AC serie pneumatic air source unit unit FRL (akayunguruzo, Igenzura ryumuvuduko, lubricator) nibikoresho byingenzi bya sisitemu yumubiri. Ibi bikoresho byemeza imikorere isanzwe yibikoresho bya pneumatike mu kuyungurura, kugenzura umuvuduko, no guhumeka umwuka.
Igikoresho cya AC seriveri ya FRL ikozwe hifashishijwe ikoranabuhanga nibikoresho bigezweho, hamwe nibikorwa byizewe nibikorwa bihamye. Mubisanzwe bikozwe muri aluminiyumu cyangwa plastike kandi bifite ibiranga uburemere bworoshye na ruswa. Igikoresho gikoresha neza filteri yibintu hamwe nigitutu kigenga indangagaciro imbere, zishobora gushungura neza umwuka no guhindura umuvuduko. Amavuta yo kwisiga akoresha inshinge zishobora guhinduka, zishobora guhindura amavuta ukurikije ibisabwa.
Igikoresho cya AC serie ya FRL ikoreshwa cyane muri sisitemu zitandukanye zifata pneumatike, nkumurongo wibyakozwe ninganda, ibikoresho bya mashini, ibikoresho byikora, nibindi. Ntabwo bitanga isoko yumwuka mwiza kandi uhamye, ahubwo binongerera igihe cyumurimo wibikoresho byumusonga kandi bitezimbere gukora neza.
