Precision Rotating Nozzle (PRN)
Toro’s Precision Rotating Stream Nozzles look and install like a standard spray nozzle, but adjust and perform like a rotor. Offering lower flows, simple arc adjustment and higher overall irrigation efficiency, this nozzle efficiently places water where you need it.
The Toro difference
Nozzle selection made easy
Two models are all that are required to cover radius requirements of 14 to 26 feet and infinitely adjustable arcs between 45° and 270º or 360º. Fewer models allow for less inventory and more flexibility.
Stronger, low trajectory streams for superior performace in wind
Lower trajectory streams provide great wind and drift resistance, resulting in significantly less overspray and misting. This is particularly effective on 12” and 6” pop-ups.
Matched precipitation rate
These nozzles deliver water more slowly and evenly than standard spray nozzles, which helps prevent runoff and water waste. Moreover, the 0.6” per hour precipitation rate better positions users to meet watering window requirements than competing rotating nozzles.
PRN’s planetary gear drive provides 10 times the torque of competitive rotating stream nozzles, delivering the necessary power to overcome debris resistance and pressure fluctuations.
Two highly versatile nozzles, full and part circle, give you a concise and flexible alternative to tackle the vast bulk of your residential irrigation needs. Toro’s PRNs are available in both male and female threads to suit all major brands of spray body types.
Regardless of inlet pressure, the Precision Rotating Stream Nozzles offer consistent rotation speed, and precipitation rates that deliver unparalleled uniformity.
Gear-Driven
Utilises a proven planetary gear drive, variable stator and turbine to rotate the nozzle.
Fewer models
Only two male-threaded nozzles and two female-threaded nozzles are required to cover radius range from 14-26 feet (4,3m-8,0m) and arc range from 45-360°.
Matched Precipitation Rate of 0.55”/hr. (14 mm/hr.)
These nozzles deliver water more slowly and evenly than standard spray nozzles. The precipitation rate of 0.55”/hr. (14 mm/hr.) helps prevent excess run times often set to stay within watering windows.
Consistent Speed of Rotation
The gear drive mechanism delivers a consistent speed of rotation regardless of system pressure and prevents product stalling at low pressure.
