    Features

    With 34 nozzle choices, a 4.9 to 14.0 m radius, and 6 body choices, the I-20 is an indispensable rotor. Whether you’ve got a small area, sandy soil, or a mix of shrubs and grass, the I-20 is ready to water with efficiency and reliability. Recent improvements include automatic arc return (non-reversing 360, from 50 to 360 degrees) and a non-strippable, vandal-proof drive mechanism that prevents gear stripping and saves repair costs. Adding FloStop™ control, easy, through-the-top arc adjustment, and a standard drain-check valve all equate to a rotor that stands second-to-none in its class.

    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 is flexible for all landscapes and decreases inventory
    Headed and slotted setscrew allows radius adjustment with a Hunter Wrench or flat-blade screwdriver
    FloStop™ closes the flow of water from individual sprinklers for nozzle changes or repairs
    Flat-top nozzles allow fast, easy insertion
    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.

    Advanced Feature - Auto Arc Return

    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.

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

    Headed and Slotted Set Screw

    Use a slotted screwdriver or the Hunter wrench for easier and simpler adjustments as needed.

    FloStop® Control

    FloStop closes the flow of water from individual sprinkler heads while the system is running. This is ideal for changing nozzles or turning off specific heads during maintenance and construction.

    Advanced Feature - FloStop Control

    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.
