Rainbird Varible Arc Rotary Nozzle 45-Degree to 270-Degree with Adjustable Radius, 17' to 24' 17-24 ft adjustable pattern rotary nozzle Low precipitation rate - 0.60 in/hr (15,2 mm/hr) - 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 With approximately 60% less flow than conventional spray nozzles, Rotary Nozzles allow more heads per zone
