Air-powered siphon spray guns and power washers use compressed air to pressurize water or other liquids for cleaning applications. Siphon spray guns emit a pressurized mist of water, cleaning solutions, paint, stain, undercoating, and lubricants. They are commonly used for cleaning equipment and applying coatings. Power washers produce a high-volume jet of water that loosens and removes dirt, grime, and other deposits from heavy machinery, floors, tanks, and storage areas. They reduce or eliminate the need to scrub surfaces or use cleaning agents.
