An exemplary mixer includes a cylindrical wall having a center axis, a substantially tubular wall defining a volute oriented about the center axis, an inlet to the volute, an exit to the volute provided by one or more openings in the cylindrical wall wherein the volute imparts a tangential velocity component to gas exiting the volute and a mount to mount the mixer to an inlet to a compressor wherein the tangential velocity component imparted by the orientation of the volute is in the intended direction of rotation of a compressor wheel of the compressor. Such a mixer can improve compressor stability, especially where the gas is exhaust gas for exhaust gas recirculation. Other methods, device, systems are also disclosed.
