ABSTRACT:
An improved venturi eductor for proportional dispensing of chemicals into flowing water includes a large antisyphoning air gap to satisfy water system regulations. Specialized baffles are provided to prevent discharge of spray and mist from the air gap. Further, the shape and location of various nozzles within the device creates a slight suction at the air gap to further limit overspray.
