I-oil-water separator isetyenziselwa ukwahlula amanzi kunye neoli kwi-Compressed air, kunye nomoya oQinisekileyo uhlanjululwa kwangaphambili.Isahluli samanzi e-oyile sisebenza ngokwahlula amathontsi e-oyile kunye namanzi ngomlinganiselo woxinaniso womoya oxinanisiweyo ngotshintsho oluphawulekayo kwindlela yokuhamba kunye nesantya njengoko umoya oQinisekileyo ungena kwisahluli.Emva kokuba umoya ocinezelweyo ungene kwiqokobhe lomhluli ukusuka kwindawo yokungena, ukuhamba komoya kuqala kubethwa yipleyiti ye-baffle, kwaye emva koko ibuyele ezantsi kwaye iphinde ibuyele phezulu kwakhona, idala ukujikeleza kwesetyhula.Ngale ndlela, amaconsi amanzi kunye neoli yeoli ahlukaniswe emoyeni kwaye ahlaliswe phantsi kwegobolondo phantsi kwesenzo se-Centrifugal Force kunye ne-inertia force.
