Building on Rain Bird’s legacy of high efficiency irrigation nozzles, the HE-VAN series combines water saving performance with the convenience and versatility of variable arc nozzles. Up to 30% more efficient than other adjustable nozzles, HE-VAN nozzles can help you save water in any pop-up spray zone, correcting for uneven coverage and helping to reduce watering run times. They can replace the nozzles on most major brands of spray heads. Producing larger droplets that fall quickly and resist wind-blown overspray, HE-VAN nozzles also help you keep water on the grass, not on the sidewalk, driveway or buildings. With a simple twist of the nozzle collar you can adjust the spray pattern from 0 degree to 360 degrees. Spray distance is adjusted by a top screw, allowing you to reduce nozzle throw up to 25%. All feature Rain Bird’s MPR (matched precipitation rate) watering distribution allowing them to be mixed with other MPR spray heads on the same zone regardless of spray adjustment.
