R33 Rotator
R33 Rotator®
The R33 Rotator® is an innovation that saves money, saves time, and performs better than the 3/4” brass impact sprinklers it’s designed to replace. The R33 uses Nelson’s proven Rotator® technology to provide longer throw distance, fight the wind and deliver uniform coverage. While brass sprinklers are prone to damage, clogging, and theft, the R33 is easy to clean, easy to repair, and costs less. The R33LP is a low-pressure version of the R33. The pressure range of the R33 is 40-65 PSI (2.75-4.5 bar), while the R33LP is 25-50 PSI (1.75-3.5 bar).
Use the R33 and R33LP for overhead irrigation, cooling, and environmental control for nursery crops, tree, vine, small fruit, and berry crops. It’s also perfect for revegetation, mining, and other specialty uses.
