Features

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 fields, public parks, and commercial environments. If efficiency, effective irrigation, and beautiful results are the goal, the I-40 is the irrigation professional's best solution.

Key Benefits

Patented automatic arc return feature returns the turret back to the original arc pattern if vandalized; 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
Color-coded nozzles make identification easy
Available opposing nozzle model for even watering in full-circle applications (I-40-ON model)
Drain Check Valve prevents low-head drainage (up to 15' 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

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

Advanced Feature - Auto Arc Return

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

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

Advanced Feature - Part- And Full-Circle in One Model

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

I40 Opposing Nozzles

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

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

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