Abstract: A liquid separator includes a housing, a separation chamber disposed within the housing and having a substantially cylindrical inner surface, wherein the inner surface of the separation chamber is aligned about a substantially vertical chamber axis, an inlet channel configured to communicate the fluid stream from a first inlet end to a second inlet end disposed within the housing and proximate an upper region of the separation chamber, and an outlet channel configured to communicate the fluid stream from a first outlet end positioned proximate the upper region of the separation chamber, to a second outlet end remote from the separation chamber. Proximate the second inlet end the inlet channel is aligned about an inlet axis. A deflector vane may also be provided which is substantially aligned about the chamber axis and intersecting the inlet axis. The inlet axis is preferably proximate to and substantially parallel with a tangent to the inner surface of the separation chamber.
