Abstract: An air/oil separator used with a closed loop oil seal system for a liquid ring vacuum pump, which incorporates a multi-chambered design for facilitating multiple stages of oil particulate separation is disclosed. The separator includes a rectangular reservoir tank and a tubular internal filter housing, which supports a filter element inside the reservoir tank. The filter housing extends horizontally inside the reservoir tank with an open distal end disposed within the reservoir tank and a closed proximal end protrudes from the proximal end wall of the reservoir tank. Extending horizontal across substantially the length of the reservoir tank, the filter housing and two internal baffle plates divide the reservoir tank into an upper inlet chamber and two collection chambers.

Abstract: An air/oil separator used with a closed loop oil seal system for a liquid ring vacuum pump, which incorporates a multi-chambered design for facilitating multiple stages of oil particulate separation is disclosed. The separator includes a cylindrical multi-chambered accumulator and a cylindrical filter housing, which supports a conventional filter element. The accumulator has an outer housing and an inner housing, which defines an outer reservoir chamber and an inner reservoir chamber. The accumulator also includes an inner oil conduit extending through the inner reservoir chamber, which deposits the oil discharge into the inner reservoir chamber. A perforated inner baffle is mounted within the inner housing to partially divide the inner reservoir chamber. A second outer baffle is mounted inside the outer reservoir chamber between the outer and inner housings to partially divide the outer reservoir chamber.
