The HP Foamer is a 2 GPM @ 700 PSI foam applicator for projecting foaming chemicals on to any surface up close or at a distance. This venturi injection system uses high water pressure (400 - 700 PSI) to draw and blend chemical concentrate 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 foam hose and fan nozzle at distances up to 13 feet.
