EDUCTOR WITH BACKFLOW DEFLECTOR

Air gap eductor with backflow deflector deflects backflowing liquid, preventing backflowing liquid from contaminating water supply by contacting water jet nozzle above air gap. Backflow deflector plate blocks 40-80% of rim area at opening at upper end of eductor discharge tube, leaving 60-20% of rim...

Zusammenfassung:	Air gap eductor with backflow deflector deflects backflowing liquid, preventing backflowing liquid from contaminating water supply by contacting water jet nozzle above air gap. Backflow deflector plate blocks 40-80% of rim area at opening at upper end of eductor discharge tube, leaving 60-20% of rim area unblocked. With bifurcated asymmetry of from 40% to 100%, blocked and unblocked rim areas deflect backflowing liquid laterally, away from water jet nozzle.
