The 2-Hose Acid Spray-All / Acid Airless Foamer is a dual-function spray and foam applicator for applying 2 different chemicals, such as those used to remove concrete and for aluminum brightening. This acid-resistant venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend the chemical concentrates into the water stream. The foaming solution then flows through the foam hose to the "airless" foam wand which draws in atmospheric air to create and project wet, clinging foam on to any surface. The other solution is projected through a separate hose in a fan pattern spray.
