VorTech is a 'swirl-abrasive' system, borne out of the 'Jos' (pron. 'Yoss') technology, originally developed in Germany, in the 1980's. The system uses a selected abrasive carried by a flow of compressed air to a nozzle, at which point, water is added. The mixture then passes through the nozzle and exits in a vortex, which is directed at the substrate to be cleaned.
