High efficiency rotary nozzle. Low precipitation rate 0.60 in. per hour (15.2 mm per hour) reduces run-off and erosion. Multiple, rotating streams uniformly distribute water throughout the radius range. Matched precipitation rate across radii and pattern simplify the design process. Maintains highly efficient performance throughout the 20 psi to 55 psi pressure range, with no misting or fogging at high pressures. Multi-stream rotary sprinkler nozzle with removable 200 mesh filter.
