摘要： The present invention is a mixing device for producing compressed foam for an extinguishing device for firefighting comprising a foam solution inlet that is operatively connected to a foam solution mixture area that is operatively connected to a compressed air inlet that is operatively connected to a compressed air injection manifold that is operatively connected to a mixing chamber. The compressed air injection manifold having a plurality of lateral sides that have a plurality of holes distributed across at least one of the lateral sides. A scrubbing collector pipe that extends into the mixing chamber to form an annular flow area within the mixing chamber. The scrubbing collector pipe having a plurality of holes distributed around an outer periphery of the scrubbing collector pipe. An inner collector pipe within the scrubbing collector pipe. A compressed air foam outlet operatively connected to the scrubbing collector pipe.
