RPS75i 3/4 in. Rotor w/ Intelligent Flow Technology. The RPS 75i rotor is designed for residential and light commercial applications. This new addition to K-Rain's line of rotors retains all of the features and benefits of the RPS 75 and delivers even more! To reduce the radius and distance in other rotors on the market, the nozzle must be changed or the break-up screw must be engaged. These steps limit the maximum reduction to 25% and cause uneven watering. With the RPS 75i, a simple turn of the patented Flow Shut-Off controls distance and water flow proportionately-up to 50%. The RPS 75i delivers even water distribution, eliminates dry spots and provides better zone performance while saving water. All of this in just one rotor-the right rotor for every landscape!
