Rotary Nozzles provide unsurpassed design flexibility and highly efficient water distribution from 13 to 18 feet. The newest addition to Rain Birds line of water-efficient products, Rotary Nozzles help reduce water waste and make it easier to design systems. The Rotary Nozzle is a truly remarkable innovation with a low precipitation rate, highly uniform distribution, and increased radius range, all in a nozzle which fits on a Rain Bird spray head.R13-18TQ Three Quarter Rotary NozzleFewer zones, faster installs system complexity and cost are reduced because more heads can be installed per zone. Rotary Nozzles can also be zoned with Rain Bird 5000/5000 Plus MPR Rotor Nozzles. Efficient water distribution multiple rotating streams deliver close-in watering and even coverage throughout the radius range. The low precipitation rate significantly reduces wasteful run-off and erosion Ultimate retrofit solution low flow rate and an expanded radius of throw solve existing spray zone inefficiencies caused by diminished pressure or stretched spacing. Eligible for a rebate of $4 back per nozzle from the Metropolitan Water District of Southern California (MWD and MWDOC). Rebate Application
