Abstract: An exhaust mixer apparatus, emissions cleaning module, and a method of manufacturing the exhaust mixer apparatus is provided. The exhaust mixer apparatus comprises an exhaust conduit, a first exhaust mixer and a second exhaust mixer. The exhaust conduit is configured to extend in an elongate direction comprising an inlet and an outlet for transporting exhaust fluid. The first exhaust mixer comprises a plurality of elongate mixing blades each having a length extending in the elongate direction. The elongate mixing blades are connected together along at least part of their lengths and arranged about the elongate direction, each elongate mixing blade comprising an outer edge extending in the elongate direction. The elongate mixing blades are twisted along their lengths such that the outer edge of each elongate mixing blade is rotated about the elongate direction. The exhaust conduit is configured to locate the first exhaust mixer in an upstream location of the exhaust conduit. The second exhaust mixer is configured to impart a swirl on an exhaust fluid when in use. The second exhaust mixer is arranged in the exhaust conduit downstream and spaced apart from the first exhaust mixer in the elongate direction.
