Hunter I-90 Ultra Rotor

Hunter I-90 Ultra Rotor

Hunter's Longest distance natural turf rotor is perfect for parks and sports.

The I-90 is Hunter’s longest distance rotor specifically designed for natural turf, parks, sports fields, and public areas. With a radius of up to 101 feet, the I-90 boasts the longest throw capability of all natural turf rotors. Yet, its reduced-size diameter and cushioned rubber cover make it the perfect choice for parks and wide-open lawn areas, as well as perimeter watering of athletic fields and horse arenas. The rotor is also easy to service, with a “jar-top” body cap that allows quick access to the filter screen and check valve with no extra pieces, parts, or tools required. The I-90 is offered in two models: a full-circle opposing-nozzle version or an adjustable arc model, each with color-coded nozzles that can be field-changed to match the specific needs of any large site.
