HUNTER I25 ULTRA ROTARY SPRINKLER:
Efficient, economical, easy to use. The ideal choice for commercial and recreational systems.
For durability, performance and economy on medium to large area sites, no other irrigation rotor brings it all together like the Hunter I-25 Ultra. A ribbed body and cap for better grip and an extra-thick heavy-duty rubber cover. The Hunter I-25 Ultra has the industry's smallest exposed surface area in it's category. The rotor includes a dozen nozzles that provide optimum performance in both primary and secondary coverage along with the patented VStat self-adjusting stator. It's compact, extra-beefy construction and an optional stainless steel riser allow for even more toughness. The I-25 Ultra Rotor Series has plenty to offer at quite an attractive price. No wonder it's the pick of so many people for countless irrigation jobs.

- Radius for I-25: 40' to 71' (12.2 to 21.6 m)
- Radius for I-25/I-31 HS: 37' to 67' (11.3 to 20.4 m)
- Recommended pressure range: 50 to 70 psi (3.4 to 4.8 bars; 344 to 482 kPa)

 Liability a top priority? The bottom line is you need ProTech
When it comes to safety at sport facilities, less is more - the less exposed surface area on your sprinkler rotors, the more safe that playing surface will be. With the ProTech safety system, the revealed portion of our heavy duty rubber cover is of the smallest possible size, minimizing the possibility of contact with athletic participants or children at play. And, with a rubber boot that surrounds the rubber cover, there are also no metal or hard plastic components close to the surface. The result is that the entire top of our I-25 Plus and I-40 commercial rotors are both flexible and user friendly. |
 New nozzles: Custom tailored uniformity
We've totally redesigned our nozzles for the I-25 Plus. Now, you replace the primary and secondary nozzles together, as a single unit resulting in uniformity at any distance from each and every nozzle. |
Unmatched Performance? It's All by Design
 With a combination of intelligent planning, carefully controlled manufacturing and frequent tests that conform to the strictest industry standards, the exceptional performance of our remarkable nozzles is no accident. Hunter is the only rotary sprinkler manufacturer that not only tests nozzles during the development stage but also performs frequent tests of every batch produced. Our world-class on site laboratory checks every production run of nozzles for gallonage output, distance of throw and numerous uniformity statistics assuring you that the nozzles you receive will meet or exceed our exacting standards. Plus, we take the extra step to check our work by asking the Center for Irrigation Technology in Fresno, California to independently test our nozzles to provide third party verification of their superior results. |
 Stainless Steel Riser - Added Strength for the Harshest Conditions
The stainless steel riser option provides added protection for the sprinkler pop-up stem and wiper seal, ensuring long life in the harshest soil conditions.
|
 VStat: A stator that's state-of-the-art
There are no stator rings required with the new VStat constant speed, self-adjusting stator. This remarkable patented innovation provides up to twice the driving force to the gear drive while adding years to the life of the product, and it's no longer necessary to disassemble the irrigation sprinkler to install "the right ring." |
 Drain Check
The standard drain check valve in our Institutional Series pop-up rotors prevents the water in the lateral piping system from escaping through the irrigation sprinklers. This water-saving feature has the side benefits of lessening the wear on irrigation system components and lowering liability issues. |
 I-25/31: When Speed is the Need
For quick, light wetdowns of sports fields or any areas that require dust control, Hunter offers the new High-Speed version I-25/31 HS, that cuts full circle rotation time from three minutes down to one. |
