Abstract: A composite fluid separator for isolting a first liquid from a second liquid having a different specific gravity. A housing (52) encloses a separation chamber (53). An inlet port (60) delivers the composite fluid into the sump (65) of the chamber. A plurality of stacked baffles (30) is positioned between the inlet and outlet ports, composed of individual inclined separation flow plates (25). The baffles create a flow path in which the fluid flows over each of the plates as it travels upward in the separation chamber toward the outlet port (50).
