Schmidt 3.5 cubic-foot portable blast pot for stripping paint, rust, and coatings off steel, concrete, and masonry. The 150 PSI rated vessel holds roughly 350 lb of abrasive per fill, so you spend more time blasting and less time reloading. It needs a serious air supply and pairs well with the 185 CFM towable compressor. Rolls around the jobsite on built-in wheels.
