The Portable 2-Way Dual 5 Gallon Uni-Body Foamer is a medium volume foam applicator for projecting up to 2 foaming chemicals on to any surface up close or at a distance. This unit features an all stainless steel cart assembly with 2 stainless steel 5 gallon jug racks. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrates into the water stream 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. The foam is then projected through the discharge hose and fan nozzle at distances up to 12 feet. Use the chemical ball valves to inject the 2 chemicals separately or simultaneously.
