Hunter I-90 Ultra 75mm Adjustable Gear Drive Sprinklers with Nozzle Rack (40mm Inlet)

The Hunter I-90 Ultra is the ultimate long-distance gear-driven sprinkler, purpose-built for large turf applications such as sports fields, stadiums, parks, and public green spaces. With a remarkable radius of up to 30.8 metres, the I-90 delivers maximum coverage from a single unit, reducing the number of sprinklers required and lowering overall system costs. No other commercial sprinkler in its class combines this reach with such efficient water distribution.

Despite its powerful throw, the I-90 is engineered with a compact body and a cushioned rubber cover, making it safe and reliable for high-traffic areas. It is equally effective for perimeter watering of athletic fields, polo grounds, and horse arenas where uniform irrigation is critical. Maintenance is straightforward thanks to the jar-top body design, which provides tool-free access to the filter screen and check valve for fast servicing.

Available in two configurations — a full-circle opposing-nozzle model and an adjustable-arc version (40° to 360°) — the I-90 adapts to the unique requirements of any large-scale irrigation project. Interchangeable, colour-coded nozzles with Hunter’s exclusive PressurePort™ technology ensure precise distribution, consistent performance, and flexible on-site adjustments.
