The Hunter I-25 is a durable, gear-driven pop-up rotor engineered for large turf areas, sports fields, and commercial landscapes. Designed for reliability and easy serviceability, the I-25 provides a wide selection of performance nozzles and robust field-grade components to meet demanding irrigation specifications.

  • Available in 4 in. and 6 in. pop-up heights with plastic or stainless-steel riser options to suit turf height and durability needs.
  • Eleven factory nozzle choices provide flexibility across a 37 to 71 ft radius (11.9–21.6 m) with flows from 3.8 to 31.5 GPM for efficient large-area coverage.
  • Recommended and operating pressure range 40–100 PSI (2.5–7.0 bar); standard nozzle trajectory is 25° with an approximate precipitation rate of 0.4 in/hr (10 mm/hr).
  • Built-in check valve prevents low-head drainage and water waste; select factory-installed reclaimed-water ID cap to clearly mark non-potable lines.
  • Factory options include reclaimed-water ID and Ultra HS (high-speed rotation) models for specialty applications; HSJ-1 1" PVC swing joint is a user-installed accessory for simplified connections.
  • Serviceable design with replaceable nozzles, durable internal components, and optional stainless-steel riser choices for extended life in commercial settings.

Ideal for large turfed areas, parks, and athletic fields, the I-25 balances coverage and efficiency while remaining straightforward to maintain. Choose the appropriate pop-up height, material, and factory options to match site requirements. Backed by a 5-year limited warranty for commercial irrigation applications.

Frequently Asked Questions

What inlet size does the I-25 rotor use?
The I-25 uses a 1" female inlet (25 mm). Choose the correct SKU for your plumbing and coupling type.
How do I choose between 4 in. and 6 in. pop-up heights?
Select 4 in. for low-profile turf or shallow installs; choose 6 in. when deeper bury depth or taller turf requires a higher pop-up for proper coverage.
Can I get a reclaimed water identification cap installed?
Yes. Factory-installed reclaimed-water ID is offered on select SKUs (for example I2504R) to clearly mark non-potable lines.
What maintenance keeps the I-25 performing well?
Flush supply lines before installation, clean or replace nozzles periodically, inspect the check valve annually, and service damaged risers promptly.
