Abstract
A portable ventilator for removing deleterious gasses from a welding site provides a funnel-like collection head structurally carried by an electrically non-conductive rigid dispersement tube carrying a powering structure. The powering structure provides pressurized gas from an external source through an adjustment valve to an input nozzle carried in axial alignment in the channel defined by the dispersement tube spacedly adjacent the joinder of the collection head with the dispersement tube to output pressurized gas toward the distal output end of the dispersement tube.
