I-40

For Sports Fields and Parks, I-40 Delivers Professional Results

The I-40 is a tough commercial rotor that delivers water with accuracy and efficiency at distances up to 70 feet. Featuring diverse three-port nozzle options, a non-strippable drive, and a thick rubber cover built to prevent injury; it's no wonder this rotor is found in more stadiums than any other in the world. With the strength of stainless steel, the I-40 is built to last in the harshest sports, public park, and commercial environments. If efficiency, effective irrigation, and beautiful results are the goal, the I-40 is the irrigation professional's best solution.

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.

Automatic Arc Return [2]

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

Non-Strippable Drive [3]

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

Part- and Full-Circle in One Model [4]

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

Color Coded Nozzles [5]

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

Optional Reclaimed Water ID [6]

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

Stainless Steel Riser [7]

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

Drain Check Valve (up to 10 ft. of elevation) [8]

The drain check valve keeps lines from draining when the system is shut off. This saves water, reduces liability, and increases system life.
