The Portable 20 Gallon Freedom LC Foamer is a medium volume venturi foam applicator that projects foaming chemicals on to any surface up close or at distances up to 12 feet. Designed for facilities require portability and may need to use more than one foaming chemical. Switch to a different chemical by simply swapping concentrate container. This system features a rugged 1/4" Yamada air pump to draw water from the 20 gallon tank and provide the water pressure for the LC venturi foamer. The LC foamer body draws and blends chemical concentrate from a 1-gallon container of chemical concentrate into the water stream to create an accurately diluted solution. Compressed air is injected into the solution to greatly increase volume and coverage ability. Rich, clinging foam is projected through the hose, wand and fan nozzle.
