The 2-Hose Uni-Body 315 Sanitize / Rinse - LV Foam System is a three function cleaning system with a low 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 dedicated foam hose and fan nozzle at distances up to 9 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 sanitizer hose and nozzle, or use an optional more powerful rinse nozzle.
