The HPSS / HPSS Foam Hose Drop Station combines two chemical foam applicators into one station with a single water connection. Two chemicals or two dilutions of the same chemical can be applied in sequence, or both foamers can operate at the same time when water volume is sufficient (2 GPM x2 @ 700 PSI). This stainless steel venturi injection system uses high water pressure (400 - 1000 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 onto any surface up close or at distances up to 13 feet.
