The Portable W-20SS Sanitize / HPSS Foam Hose Drop Station is a combination foam/sanitizer applicator featuring an all stainless steel cart assembly. It will apply one chemical as foam at 2 GPM @ 700 PSI and another as a sanitizing spray at 3 GPM @ 700 PSI through separate hoses. This stainless steel venturi injection system uses high water pressure (400 - 1000 PSI) to draw and blend chemical concentrates into the water streams to create accurately diluted solutions using precision metering tips to control chemical usage. Rich, clinging foam is created by injecting compressed air into the foaming solution to greatly increase volume and coverage ability. The foaming solution is then projected through the foam hose and fan nozzle on to any surface up close or at distances up to 13 feet. Sanitizer solution, or any other chemical, is projected using the trigger gun and fan nozzle.
