Rain Bird HE-VAN High-Efficiency Variable Arc Nozzles

The Rain Bird HE-VAN Series represents a significant advancement in spray head technology, engineered to deliver high-efficiency water distribution for residential and commercial landscapes. These High-Efficiency Variable Arc Nozzles are fully adjustable from 0° to 360°, allowing for precise coverage in irregularly shaped zones while maintaining a clean, defined edge. Technical performance is characterized by a unique stream pattern that produces large, wind-resistant water droplets. This design minimizes misting and airborne evaporation, ensuring that water reaches the intended target even in challenging environmental conditions. HE-VAN nozzles achieve a Distribution Uniformity (DULQ) average of 70%, marking a 40% improvement over typical variable arc nozzles, which allows for reduced zone run times by up to 35%.

Operational specifications include a radius range of 6 to 15 feet (1.8 to 4.6 meters) and a working pressure range of 15 to 30 psi, with optimum performance achieved at 30 psi. The series is color-coded for easy identification of radii (8′, 10′, 12′, and 15′) and features matched precipitation rates (MPR), enabling them to be installed on the same zone as Rain Bird MPR and U-Series nozzles. Additional hardware features include a tactile click to prevent arc drift over time and gentle close-in watering to eliminate dry spots around the spray head. Backed by a three-year trade warranty, the HE-VAN Series is a technical standard for irrigation professionals seeking to maximize water conservation without compromising landscape health through superior scheduling coefficients and uniform application.
