HUNTER I-20 ROTOR SERIES

Diverse and Efficient to Meet Any Need.

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. With 34 nozzle choices, a 4.9 to 14 m radius, and six body choices, the I-20 is an indispensable rotor. Recent improvements include automatic arc return; non-reversing, adjustable arc from 50° to 360°, and a non-strippable, vandal-proof drive mechanism. Optional pressure-regulated bodies will take incoming pressures of 3.4 to 6.9 bar; 345 to 690 kPa and reduce them to 3.1 bar; 310 kPa, saving up to 25 percent more water. Additional features like FloStop® control, easy through-the-top arc adjustment, and a standard drain-check valve make the I–20 rotor top in its class.

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°.
• 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..
• 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.
