Idivayisi ye-FRL yochungechunge lwe-PNEUMATIC AC iyithuluzi elihlanganisa umthombo womoya wokwelapha ohlanganisa isihlungi somoya, isilawuli sokucindezela, nesilubricator.
Le divayisi isetshenziswa kakhulu ezinhlelweni ze-pneumatic, ezingasefa ngempumelelo ukungcola nezinhlayiya ezisemoyeni, ziqinisekise ukuhlanzeka komoya wangaphakathi ohlelweni. Ngesikhathi esifanayo, iphinde ibe nomsebenzi wokulawula ingcindezi, ongalungisa ukucindezela komoya ohlelweni njengoba kudingeka ukuze kuqinisekiswe ukusebenza okuvamile kwesistimu. Ngaphezu kwalokho, i-lubricator ingaphinde inikeze ukuthambisa okudingekayo kwezingxenye zomoya ohlelweni, ukunciphisa ukungqubuzana nokuguga, futhi andise impilo yesevisi yezingxenye.
Idivayisi ye-FRL ye-PNEUMATIC AC yochungechunge inezici zesakhiwo esihlangene, ukufakwa okulula, nokusebenza okulula. Yamukela ubuchwepheshe obuphambili be-pneumatic futhi inamandla okuhlunga kahle nokulawula ingcindezi, iqinisekisa ukuzinza nokuthembeka kwesistimu ye-pneumatic.
