The Foam-All Pro is a professional LOW VOLUME foamer for applying foaming chemicals with minimal overspray. 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. 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 discharge hose and fan nozzle onto any surface up close or at distances up to 9 feet. Gauges display incoming water and air pressure to assist with setup and optimize performance.
