The Hunter I-80 Rotor is a commercial-grade rotor engineered for sports turf, golf courses, and large landscape installations. This 4-inch pop-up model pairs a ratcheting stainless-steel riser with a factory-installed check valve and a robust, dirt-tolerant gear drive for reliable, long-term performance.

  • Adjustable arc: 70° to 360° for partial and full-circle coverage, settable without excavation.
  • Radius & flow: Approximately 63–97 ft radius (19.2–29.6 m); flow range depends on nozzle choice and pressure.
  • Nozzle options: Seven standard 22.5° nozzle choices with wind‑fighting, dual‑trajectory performance.
  • Durable construction: Ratcheting stainless-steel riser, heavy-duty gear drive, and factory check valve for anti-siphon protection.
  • Pressure & rating: Recommended operating range 65–100 PSI; all I-80 rotors are pressure-rated to 150 PSI and backed by a 5-year warranty.

Designed for easy maintenance, the I-80 features Hunter’s Total-Top-Service (TTS) no‑dig access that lets technicians service the riser and replace nozzles from the surface. Choose the I-80 when you need commercial durability, simplified servicing, and consistent, wind-resistant coverage across large turf areas.
