– Next is the anti-insect feature: After the water supply is turned off, the sprinkler plate drops down to seal the nozzle opening, preventing insect intrusion. Additionally, a special advantage is the clip mounted on the rotating disc that helps limit the spray radius. This is particularly suitable for localized sprinkler irrigation for fruit trees. When the tree is small – the irrigation range is only about 1m on each side; as the tree grows, removing the radius-limiting clip will increase the coverage, reaching a maximum radius of up to 7.5m (depending on the selected radius when purchasing the product).
