Relax with the knowledge your landscape is being watered by reliable 5000 Series Rotors and industry-leading Rain Curtain Nozzle Technology. Rain Bird® 5000 Series Rotors are ideal for medium to large-size hillsides and shrub areas and evenly distribute water from 25 to 50 feet. Superior Distribution Uniformity. 5000 Series Rotors with Rain Curtain Technology are engineered to deliver a uniform spray pattern, giving you a consistently green lawn throughout. The larger water droplets produced by Rain Curtain technology prevent misting and airborne evaporation so the right amount of water is delivered to the right place, saving you water and money. Gentle close-in watering eliminates dry spots around the rotor, prevents seed washout and allows the turf to grow healthy with no matting or bending.
