The Internal 5 Gallon Tank Foamer is a low-volume foam applicator with an all stainless steel cart assembly for applying ready-to-use foaming chemicals. Connect compressed air to pressurize the 316L stainless steel ASME rated tank and to inject air into the solution to greatly increase volume and coverage ability. A low-volume of rich, clinging foam is projected on to any surface up close or at distances up to 9 feet. Each fill provides 10 minutes of foaming time.
