Abstract: A fluid separation device (20) is provided for separating a raw fluid (51) into a plurality of components (36, 37 and 38). A body (21) has a cylindrical bore (39) defined by an inner wall (41) of the body (21). A generally solid cylindrical core (22) has a helical channel (46) formed in a periphery of the cylindrical core (22). The helical channel (46) has a generally rectangular cross-section. The cylindrical core (22) is disposed in the cylindrical bore (39) such that the inner wall (41) of the body (21) and the helical channel (46) form a helical coil (24). A feeder assembly (23) is in fluid communication with the helical coil (24), such that the feeder assembly (23) is operable to transport a raw fluid (51) to the helical coil (24). A splitter assembly (25) is also in fluid communication with the helical coil (24 ). The splitter assembly (25) comprises at least one separator vane (31) defining a plurality of conduits.
