A fluid takeoff assembly for a motor-compressor is provided and includes an outer pipe having an inlet and an outlet, and an inner pipe defining a fluid passage extending from an open axial end toward a closed axial end thereof and a radial opening fluidly coupled with the fluid passage. The inner pipe may be disposed in the outer pipe such that the open axial end and the closed axial end are oriented toward the outlet and the inlet, respectively, and the inner and outer pipes define an annular space therebetween. A cross-flow member may be coupled with the inner pipe and may define a flowpath fluidly coupled with the fluid passage via the radial opening. A vane and the cross-flow member may be disposed in the annular space and configured to at least partially induce a swirling flow in a process fluid flowing through the annular space.
