Hunter I-90 ADV Adjustable Rotor with Check Valve – BSP 1½"

The Hunter I-90 ADV Adjustable Rotor with Check Valve – BSP 1½" is Hunter's premier long-range rotary sprinkler engineered specifically for the needs of professional-grade turf irrigation. With a powerful throw radius of up to 31.4 metres, the I-90 is ideal for expansive landscapes such as sports fields, public parks, golf course perimeters, and horse arenas.

This ADV model features a field-adjustable arc (from 50° to 360°), allowing flexible installation and reducing inventory requirements. The unit is equipped with a drain check valve (rated for up to 2 m elevation) that conserves water by preventing low-head drainage, while the exclusive PressurePort™ Technology ensures accurate, uniform water distribution across the entire coverage area.

The compact rotor body is built for durability, with a cushioned rubber top and jar-top access for tool-free servicing of the internal check valve and filter screen. The I-90 ADV is trusted for its reliability, efficiency, and performance in the most demanding commercial and municipal applications.
