The 517 Sanitizer is a high volume venturi injection system that uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream. Precision metering tips are used to create the lean ratios required for no-rinse sanitizing in food plants. The solution is projected through the discharge hose and fan nozzle as a 5.4 GPM, heavy spray for fast and efficient coverage.
