I-90

HUNTER'S LONGEST DISTANCE NATURAL TURF ROTOR IS PERFECT FOR PARKS AND SPORTS FIELDS

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.

Opposing Nozzle 360˚ Model [1]

Many customers prefer the aesthetic appeal and performance of opposing nozzles. With primary and secondary nozzles on opposite sides of the turret, streams arc in opposing directions and provide highly efficient coverage at every range of throw.

I-90 Dual Trajectory Color-Coded Nozzles [2]

All I-90 Series rotors have color-coded nozzles for easy identification and, the nozzle numbers approximate the flow in gallons per minute. Choose from the eight standard 22.5 degree trajectory nozzles or the eight 15 degree nozzles for low-angle applications.

Standard 22.5 degree trajectory nozzles

Low-angle 15 degree trajectory nozzles

I-90 RECLAIMED WATER ID [3]

Purple logo caps indicate the use of non-potable irrigation. They are available as a factory installed-option or as a replacement part.

I-90 DRAIN CHECK VALVE (up to 7 ft. Elevation) [4]

As air in the system piping can cause long-term damage to rotors and plumbing, the drain check valve keeps lines from draining when the system is shut off. This saves water, reduces liability, and increases system life.
