## Abstract

A spray tank backpack apparatus for carrying spray tanks during use includes a frame having a frame left side, a frame right side, a frame top side, and a plurality of frame braces extending between the frame left side and the frame right side. A tank shelf is coupled to the frame and includes a shelf perimeter and a plurality of shelf braces. The shelf perimeter is coupled adjacent a bottom end of each of the frame left side and the frame right side. The plurality of shelf braces supports an industrial pressurized tank. A pair of hose brackets is coupled to the frame and is configured to receive a hose of the industrial pressurized tank. A pair of shoulder straps is coupled to the frame to be worn like a backpack.
