ABSTRACT:
A separator includes a vessel having a peripheral wall bounding a chamber. The vessel is rotatable about a rotational axis extending through the vessel. The chamber communicates with an inlet and a first outlet. A tubular member is disposed within the chamber and communicates external thereof. A plurality of fins are disposed within the chamber. Each of the fins extends from toward the tubular member to toward the peripheral wall. A first tube projects from the tubular member to toward the peripheral wall. The first tube has a second outlet in communication with the chamber. The first outlet is disposed closer to the rotational axis than the second outlet such that during use a fluid boundary line first outlet and the second outlet.
