The WR-2 Micro-Flow Foam/Rinse/Sanitize System is a combination low volume airless foam/sanitizer applicator with a rinse mode. 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 discharge hose to the adjustable fan pattern airless foam wand which draws in atmospheric air to create and project wet, clinging foam on to any surface. Quick connect the pistol grip gun to apply sanitizer or to rinse in a fan pattern. The low flow rate makes this unit ideal for use in restaurants or other areas where minimal over-spray and runoff are essential.
