Abstract
A two-stage air-oil separator is connected to the air exhaust system of a compressor. The first stage has a pleated extended area agglomerator formed of layers of glass fiber material. The second stage has radially spaced filter elements with high loft filter material layers held between vinyl-coated glass scrims. The layers in the various filter elements are wrapped with different tightness. Fluid inlets and outlets are provided.

Separator apparatus comprising;
- upper and lower supports
- radially spaced annular permeable casings concentrically disposed about a central axial core,
- first and second spaced filter means disposed concentrically about the central axial core respectively on opposite sides of one of said permeable casings and extending axially between the supports for agglomerating and filtering fluids,
- said first filter means comprising pleated agglomerator media means having upper and lower ends disposed in sealing relationship with the upper and lower supports respectively,
- said second filter means comprising radially spaced annular filter elements concentrically disposed about the core, wrapped directly adjacent on the outer radial side of one of said permeable casings, the annular filter elements comprising layers of filter material having relatively high loft having upper and lower ends disposed in sealing relationship with the upper and lower supports respectively,
- said casings, said annular filter elements and said agglomerator media means having upper and lower ends disposed in sealing relationship with the upper and lower supports respectively.

Separator apparatus comprising;
- upper and lower supports
- radially spaced annular permeable casings concentrically disposed about a central axial core,
- filter means disposed concentrically about the central axial core, the filter means comprising;
- first and second radially spaced annular filter elements, and annular pleated agglomerator media means, the agglomerator media means comprising a flat sheet agglomerator material interposed between a single layer of high loft agglomerator material and two superposed layers of high loft agglomerator material, said single layer received on a surface of the flat sheet agglomerator material, which surface faces radially outward from the core, and the agglomerator media means comprises sequentially from an outermost radial side thereof to an innermost radial side a first mesh screen outwardly adjacent to the single layer of high loft agglomerator material, which is outwardly adjacent to the flat sheet agglomerator material, which in turn is outwardly adjacent to the two superposed layers of agglomerator material, which are outwardly adjacent to a second mesh screen,
- the annular pleated agglomerator means being disposed radially inward of and adjacent to an outer one of the permeable casings and being disposed outward of an inner one of the permeable casings,
- the annular pleated agglomerator media extending between said upper and lower supports.
