The 1-Hose Uni-Body 517 Sanitize / Rinse / LC Foam System is a three-function cleaning system with a medium volume foamer. The venturi injector uses standard city water pressure (35 – 125 PSI) to draw two chemical concentrates into the water stream and create accurately diluted solutions. Compressed air is injected into the foaming solution to greatly increase volume and coverage ability, and the foam is projected through the hose and fan nozzle at distances up to 12 feet. Sanitizer solution is projected as a fan pattern spray at the lean ratios required for no-rinse sanitizing in food plants. Rinse through the same hose and nozzle, or use an optional more powerful rinse nozzle.
