1. An air/oil separator, comprising:
an air manifold having an air outlet and an air manifold centerline axis;
an oil manifold having a first air/oil inlet and a second air/oil inlet, the oil manifold extending circumferentially about the air manifold centerline axis and an entirety of the oil manifold extending radially outward of the air manifold;
a first rotating separation chamber defined by a first body, the first rotating separation chamber having a first rotating separation chamber bottom exiting hole and a first rotating separation chamber oil outlet channel fluidly coupled to the first rotating separation chamber bottom exiting hole, the first rotating separation chamber being in communication with the first air/oil inlet and the air outlet, and the first body being configured to induce a rotation of an air/oil mixture in the first rotating separation chamber to separate air of the air/oil mixture from oil of the air/oil mixture and to guide the air towards the air outlet and the oil towards the first rotating separation chamber bottom exiting hole; and
a second rotating separation chamber defined by a second body, the second rotating separation chamber having a second rotating separation chamber bottom exiting hole and a second rotating separation chamber oil outlet channel fluidly coupled to the second rotating separation chamber bottom exiting hole, the second rotating separation chamber being separate from the first rotating separation chamber and in communication with the second air/oil inlet and the air outlet, and the second body being configured to induce a rotation of the air/oil mixture in the second rotating separation chamber to separate the air of the air/oil mixture from the oil of the air/oil mixture and to guide the air towards the air outlet and the oil towards the second rotating separation chamber bottom exiting hole,
wherein the air manifold centerline axis is parallel to a centerline axis of the first rotating separation chamber bottom exiting hole or the second rotating separation chamber bottom exiting hole, and
wherein the first rotating separation chamber oil outlet channel and the second rotating separation chamber oil outlet channel are separate and are each fluidly coupled between their respective bottom exiting hole and an oil tank.
