A demister assembly is provided for removing and reclaiming liquids from gases, and particularly engine lubricating oil aerosols from leakage air in gas turbine engines. When in series connection to an air vent line from a gas turbine engine, the demister strips out oil from the air before it is vented overboard while producing a moderate noise reduction and imposing only slightly higher back pressure on the system.By increasing in number selected demister components, the noise reduction can be significantly increased with minimal increase in back pressure, combining a silencer function with the demister function.
