Product details

The Hunter I-20 Ultra pop-up sprinkler is the professional version of the Hunter PGP – the world’s best selling rotor sprinkler.

The Hunter I-20 sprinkler features a FloStop valve to allow an individual nozzle to be shut off and a heavy duty construction with a stainless steel riser. A check valve prevents puddling out of the lowest sprinklers on sloping sites.

The I-20 is ideal for larger lawn and turn areas such as large private gardens, corporate headquarters and commercial landscape applications. Hunter Industries are a world leader in pop up sprinkler technology and their pop up sprinkler range is designed for use by professional landscapers.

The I20 has a set of 8 standard nozzles that cover between 8.5m and 13.7m radius @ 3.5bar pressure (operating pressure 1.7 – 4.5 bar). Short radius nozzle set is designed to provide a 5.5m or 7.6m radius @ 3.5 bar pressure; 3 nozzles are included for each nozzle allowing matched precipitation on 90, 180 and 360 degree arcs.

  • 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 to change the nozzle or perform 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)
