The Rain Bird 18RNFPRO high efficiency rotary nozzle offers water savings of up to 30% over a standard pop-up spray nozzle. It covers a distance from 13-18 feet with a full 360 degree watering pattern. Rotating streams of large water droplets reduce runoff and provide uniform coverage， even in windy conditions. The 18RNFPRO can replace your current pop-up full pattern sprays to start saving water. To clear debris that may block part of the nozzle simply pull up the nozzle while water is running， and the debris will be flushed out.Find the NOZZLE ROTARY FC 18' at Ace.
