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.
