Abstract:
A spray system with a dual induction process comprising:an atomizing tube, said atomizing tube generally cylindrical and hollow, including sidewalls, as well as an atomizing tube entrance and an atomizing tube exit,a jet nozzle, said jet nozzle residing within said atomizing tube proximal said entrance, said nozzle having a nozzle entrance and a nozzle exit,a plurality of induction ports, said induction ports passing through said sidewalls, said induction ports further in communication with a region proximal said jet nozzle exit,a removable venturi element, said venturi element being downstream of said jet nozzle and residing within said atomizing tube, said venturi element including an aperture, said aperture passing through said sidewalls and is in communication with a reservoir of material, whereby a low power compressor provides compressed air to said jet nozzle, as the compressed air passes through said jet nozzle the air's pressure is reduced, thereby causing air to be inducted through said plurality of induction ports, the air continues to travel through said venturi element where the pressure remains low enough to induct said material from said reservoir into said venturi element where said material is atomized and further propelled to said atomizing tube exit where it is delivered to the target.
