These two animations show how the Hydro Gap ™ Air Gap Eductor mixes water and chemicals to dilute concentrations while preventing against backflow.

Mixing Water and Chemicals:
1. incoming water stream is restricted by a nozzle;
2. the water stream crosses the air gap safety zone;
3. while the speed of the outgoing water is decreased by the inverted funnel shape at the bottom of the second venturi; this results in a vacuum in the middle, where the chemical is sucked into the water stream;
4. chemical flow is regulated by interchangeable metering tips;
5. water and chemical are thoroughly mixed as they leave the outlet.
