Abstract

A filter is provided for coalescing droplets of oil in a stream of gas, comprising an oil coalescing layer of a microfibrous material and a second layer of an oil drainage material located downstream of and in face to face contact with the first layer. The drainage layer is for receiving oil from the coalescing layer and for providing a path for oil to flow by gravity from the filter. Oil carry-over is reduced by providing a drainage layer which comprises at least one inner layer of polyester fabric in an embodiment of spunbonded construction and in an embodiment of polyester filament of trilobal cross- section and an outer layer of different construction.
