Abstract

There is disclosed a separator having a first separator and a matrix separator. The first separator caters to an air-oil mixture having a first oil concentration and the matrix separator caters to an air-oil mixture having a second oil concentration being less than the first oil concentration. The matrix separator is disposed at least partially concentrically within the first separator. A wall is disposed radially between the first and second separators. A radial passage extends through the wall. An air-oil mixture outlet of the first separator is fluidly connected to an air-oil mixture inlet of the matrix separator via the radial passage. At least one passage extends radially outwardly from the matrix separator across the first separator. The at least one passage fluidly connects the matrix separator to an environment outside the air-oil separator. A method of removing oil from an air-oil mixture is also disclosed.
