The 2-Hose WR-2 Foam/Rinse/Sanitize System is designed for use when the foaming and sanitizing chemicals are not compatible. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. The foaming solution then flows through the dedicated foam hose to the airless foam wand which draws in atmospheric air to create and project wet, clinging foam on to any surface up close or at distances up to 6 feet. A rinse and sanitizer are applied with the second hose and project a fan pattern spray using the pistol grip gun.
