An inertial gas-liquid impactor separator includes flow director guidance structure directing and guiding flow through the housing from the inlet to the outlet along a flow path from upstream to downstream. The flow director guidance structure may include a flow controller controlling and directing flow.

An aftertreatment system comprises a housing defining an internal volume. The housing includes an inlet, an outlet and a first sidewall. A sleeve is positioned within the internal volume and protrudes through the first sidewall. An inner shell is positioned within an inner region defined by the sleeve and defines a recess therein. The inner shell spaced apart from the sleeve so as to define a channel therebetween. A base is positioned within the recess and includes an injection port which is in communication with the internal volume. An injector is disposed on the base and is disposed completely within the recess. The injector is in fluidic communication with the internal volume via the injection port. The injector is configured to inject an exhaust reductant into the internal volume via the opening. A cover plate can be disposed over the recess and structured to prevent objects from impacting the injector.

A filter assembly includes a laterally extending filter element having an element plate extending laterally outwardly therefrom and mounted between axially spaced first and second housing shells. First and second sets of one or more windows are formed axially through the element plate and define a flow path through the assembly.

An inertial gas-liquid impactor separator and method is provided, including multiple stages and multiple variable flow controllers.
