The Portable WR-2 Foam/Rinse/Sanitize System is a combination medium volume airless foam/rinse/sanitizer applicator featuring the unique all-in-one SmartWand™. Featuring an all stainless steel cart assembly, 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 and the SmartWand™ 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. Simply open the appropriate ball valve and rotate the SmartWand™ to use the fan pattern spray setting to apply sanitizer or to rinse at full pressure.
