The Portable 40 Gallon HVHC Foamer is a high volume "high concentrate" foam applicator that will produce strong dilution ratios for the toughest cleaning jobs, mounted on an all stainless steel cart. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate from the 40 gallon tank into the water stream to create create a very strong chemical solution. A high volume of 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 on to any surface up close or at distances up to 15 feet (25 feet with zero degree nozzle).
