Hunter I-Series Rotors Product Guide

Learn about recent product improvements that raise the bar for durability and performance, and why there is no better commercial sprinkler than Hunte

All Product Videos

Features

The I-90 is Hunter's longest-distance rotary sprinkler specifically designed for natural turf, parks, sports fields, and public areas. With a radius up to 30.8 m from a single sprinkler, the I-90 boasts a coverage area no other commercial sprinkler can deliver. 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 model and an adjustable arc model, each with colour-coded nozzles that can be field-changed to match the specific needs of any large site.

Key Benefits

Exclusive PressurePort™ Technology creates exceptional nozzle uniformity
Forward-facing triple nozzles (I-90), opposing triple nozzles (I-90-ON) create uniform nozzle profiles in part- and full-circle applications
QuickCheck™ Arc Mechanism for fast arc adjustment and review of the arc setting
Part- and full-circle in one model provides flexible installation options and decreases inventory (I-90)
Drain Check Valve prevents low-head drainage (up to 2 meters of elevation)

Advanced Features

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.

Advanced Feature - Opposing Nozzle 360 Model

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.

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 Reclaimed Cap

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.
