The Portable 517 Sanitize/Rinse/LV Foam Hose Drop Station is a combination applicator for cleaning small to medium surfaces. Designed to apply one chemical as foam, another as a sanitizing spray and for rinsing. Featuring an all stainless steel cart assembly, this venturi injection system uses standard city water pressure (35 - 125 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 discharge hose and fan nozzle at distances up to 9 feet. Use the same hose and nozzle to apply sanitizer solution. Rinse at full pressure using the unique, powerful 4-hole nozzle.
