Iyunithi yokucubungula umthombo womoya wochungechunge lwe-Pneumatic AW iyisisetshenziswa somoya esifakwe isihlungi, isilawuli somfutho, kanye negeji yokucindezela. Isetshenziswa kabanzi emkhakheni wezimboni ukuphatha ukungcola emithonjeni yomoya futhi ilawule ingcindezi yokusebenza. Le mishini inokusebenza okuthembekile nokusebenza kahle kokuhlunga, okungasusa ngokuphumelelayo izinhlayiya, inkungu kawoyela, nomswakama emoyeni ukuze kuvikelwe ukusebenza okuvamile kwemishini yomoya.
Ingxenye yokuhlunga yochungechunge lweyunithi yokucubungula umthombo womoya ye-AW isebenzisa ubuchwepheshe bokuhlunga obuthuthukisiwe, obungakwazi ukuhlunga ngempumelelo izinhlayiya ezincane nokungcola okuqinile emoyeni, inikeze umoya ohlanzekile. Ngesikhathi esifanayo, isilawuli sokucindezela singalungiswa ngokunembile ngokuvumelana nesidingo, siqinisekise ukukhishwa okuzinzile kokucindezela kokusebenza ngaphakathi kwebanga elimisiwe. I-gauge ye-pressure gauge ingakwazi ukuqapha ingcindezi yokusebenza ngesikhathi sangempela, ikwenze kube lula kubasebenzisi ukuthi balungise futhi balawule.
Iyunithi yokucubungula umthombo womoya inezici zesakhiwo esihlangene kanye nokufakwa kalula, futhi ilungele izinhlelo ezihlukahlukene zomoya. Ingasetshenziswa kabanzi ekukhiqizeni, embonini yezimoto, embonini ye-electronics, nakweminye imikhakha, ihlinzeka ngezixazululo ezizinzile nezithembekile zokwelashwa komthombo wegesi. Ngokungeziwe ekusebenzeni kahle kokuhlunga kanye nemisebenzi yokulawula ingcindezi, idivayisi iphinde ibe nokuqina nokuhlala isikhathi eside, okuvumela ukusebenza okuqhubekayo nokuzinzile ezindaweni zokusebenza ezinzima.
