A fluid deflector is for a fluid separator including a central axis and an enclosed wall having an open end and an inner circumferential separation surface extending about the axis to define an interior separation chamber. The fluid deflector includes a base disposable proximal to the wall open end and having a central axis collinear with the separator axis. A plurality of vanes are connected with the base so as to be spaced circumferentially about the central axis. The vanes define a plurality of flow channels each bounded by a separate pair of adjacent vanes and having an inlet and an outlet. Each vane directs flow through a bounded channel generally radially inwardly from the channel inlet toward the channel outlet and generally circumferentially and radially outwardly from the channel outlet.
