Hunter I-20 Ultra 100mm Adjustable Gear Drive Sprinklers (20mm BSP) - 20/Box

The Hunter I-20 Ultra is a professional-grade gear drive sprinkler built for unmatched performance across residential, commercial, and light industrial irrigation applications. With a radius range of 9 m to 14 m, the I-20 is engineered to deliver precise coverage, exceptional uniformity, and superior durability—making it one of Hunter’s most versatile rotors.

This 100mm (10 cm) pop-up model includes 20 nozzle choices, giving contractors and landscapers the flexibility to tailor water distribution to any site condition, from small turf areas to expansive mixed landscapes. With its factory-installed rubber cover, water-lubricated gear drive, and robust internal design, the I-20 is built to last in tough environments while ensuring smooth and reliable operation.

Recent innovations, including automatic arc return and non-reversing full-circle 360° rotation, prevent gear damage and simplify adjustments, while the FloStop® control allows water flow to be shut off directly at the head without disrupting the entire system. The standard drain check valve eliminates low-head drainage and water waste. Combined, these features make the I-20 an ideal choice for contractors who demand reliability and long-term efficiency.

Purchasing the box of 20 sprinklers provides excellent value for large installations and ensures consistent irrigation quality across the entire site.
