Offering both manual cleaning for waterborne paint equipment, and automated cleaning for solvent-based paint guns at one location at the same time, the G520 provides the best of both worlds. This washer also offers a filtration process for environmentally-sound waterborne paint waste disposal, and for recycling waterborne cleaning solution. The left tank offers an open design for easy waterborne spray gun cleaning; the right tank automatically cleans 2 guns & 2 cups, or 3 or 4 spray guns, solvent or waterborne, in one minute. The right tank is to be used exclusively for either solvent or waterborne. Made in the USA.
