Overview

The I-25 gets the job done with power, efficiency, and commercial-grade reliability. With a robust watering radius of 11.9 to 21.6 m, this rotor can be used in a variety of applications and environments. Its compact, highly durable design comes with an optional stainless steel riser for tough-as-nails strength. With a 5-year warranty, the I-25 also has options for reclaimed water ID and high-speed. A standard check valve is built in, and a wide selection of high performance nozzles are available. Efficient, tough, and built-to-last, Hunter’s I-25 rotors work hard day in and day out so you don't have to.

Key Benefits

Patented automatic arc return feature returns the turret back to the original arc pattern if vandalised; adjustable arc from 50° to 360°
Non-strippable drive mechanism is protected from damage if turned in the opposite direction of travel
Part- and full-circle in one model for flexibility across landscapes and reduced inventory
Colour-coded nozzles make identification easy
QuickCheck™ arc mechanism for fast arc adjustment
Available stainless steel riser for extra durability
Drain check valve prevents low-head drainage (up to 3 m of elevation)

Advanced Features

Automatic Arc Return

This patented feature returns the turret to the original arc regardless of where it is turned. This ensures vandal protection in any environment.

Non-Strippable Drive

The patented, non-strippable, vandal proof drive mechanism enables the turret to be turned without causing damage.

Part- and Full-Circle in One Model

Patented non-reversing 360 for part- and full-circle in one model, from 50 to 360 degrees.

Color Coded Nozzles

Nozzles are easier to differentiate in the field for quick reference and simple installation.

Optional Reclaimed Water ID

Purple caps indicate where non-potable irrigation water is being used.

Stainless Steel Riser

For unforgiving soil conditions, unpredictable climates, or heavy foot traffic, stainless steel is the best choice

Drain Check Valve (up to 3.0 m of elevation)

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.
