Described is a preferred rotary spray chamber device for conditioning an aerosol. The device has chamber walls defining an internal chamber and an inlet opening into the internal chamber. The inlet opening is located such that an aerosol directed into the chamber through the inlet opening tangentially contacts chamber wall areas adapted to impart a rotary motion to the aerosol within the chamber. An impact member extends inwardly into the chamber from a chamber wall location such that the member is impacted by the aerosol in its rotary motion so as to remove large droplets and thus form a conditioned aerosol. An exit opening is defined by the chamber walls through which the conditioned aerosol can exit the chamber, and a drain opening is also defined by the chamber walls through which liquid removed from the aerosol and collected in the chamber can exit the chamber.
