The Portable Rinse/LC Foam Hose Drop Station is a medium volume foam applicator featuring an all stainless steel cart assembly. It will project foaming chemicals on to any surface up close or at a distance and rinse through the same hose. 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. The foam is then projected through the discharge hose and fan nozzle at distances up to 12 feet. Switch to the powerful 4-hole nozzle and rinse at full pressure.
