The Ultimate DU Foamer is a medium volume foam applicator for simultaneously projecting 2 foaming chemicals to any surface up close or at a distance. This venturi injection system uses city water pressure (35 – 125 PSI) to draw and blend chemical concentrates into the water stream at the same time to create an accurately diluted solution. Rich, clinging foam is created by injecting compressed air into the solution to greatly increase volume and coverage ability. Foam is then projected through the hose and fan nozzle at distances up to 12 feet.
