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.
Arc setting: 40 to 360 degrees

Exclusive PressurePort™ nozzle technology
Through-the-top arc adjustment
Quick check arc mechanism
Water lubricated gear-drive
Standard factory installed nozzle: #53
Factory installed rubber logo cap
Warranty period: 5 years
The opposing nozzle design offers excellent water distribution. With primary and secondary nozzles on opposing sides of the turret, streams arc in opposite directions as the sprinkler rotates for outstanding mid-range and close-in watering.
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
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.

A Standard that Has Yet to be Matched
Hunter made its reputation on the quality, reliability and innovative features found in its rotary sprinkler line and continues to set the benchmark by which other manufacturer’s rotors are judged.
