An apparatus for removing entrapped gas in a fluid is disclosed. The invention is particularly useful in separating air from oil used in engines and transmissions. The inlet for the oil and air, the exit for the air, and the oil exit are all located at the same end of the invention. This facilitates its use in a variety of engine and transmission configurations. Oil enters tangentially at the top of a cylindrical housing and is caused to cyclonically work its way down to the bottom of the housing. The oil is then forced to reverse its flow and travel upward with a downwardly projecting shroud. The oil is forced to enter an oil outlet tube which is connected to the top of the shroud and which passes through the top of the housing. An air outlet tube projects downwardly from the center of the top portion of the housing. The oil outlet tube is located concentrically within the air outlet tube. As the air circulates within the top portion of the cylindrical housing, the oil is centrifugally forced outward, while the lighter air coalesces and moves towards the center of the apparatus. The air passes into the gap formed by the oil and air outlet tubes where it is channeled to the air exit tube. In other embodiments, the apparatus includes a filter which filters out solid particles; includes an internal pressure through a relief valve which permits the oil to bypass the filter if it becomes clogged sufficiently to prohibit the passage of oil through the filter; includes a false bottom where the solid particles are trapped thereby permitting ease of the removal of the filter; includes around the filter a shroud which helps insure that little or no air passes through the filter.
