PRODUCT FEATURES AND BENEFITS

FloStop Control…

Flow shut-off for individual dry nozzle and arc changes

Do you want to change a nozzle while the system is running? Do you want to be able to stop the low of water through a particular sprinkler while you adjust a neighboring head on the same zone? Is one area receiving too much water and you want to shut off just that one rotor? Only the I-20 Ultra with the innovative FloStop control allows you to temporarily turn off the low of water through an individual head while the rest of the zone operates.

Six Rotor Models…

Shrub, 4", 6" and 12" pop-up

The Hunter I-20 Ultra comes in two turf heights, the 4" (10 cm) and 6" (15 cm) popup models, along with the 12" (30 cm) highpop model, and the I-10 riser-mounted shrub model. The I-20 Ultra 4" and 6" pop-ups are also available with the optional stainless-steel riser sleeve, and all models may be ordered with a purple rubber cover for reclaimed water identiication. The innovative FloStop is standard on all models.

6" Rotor Models…

Two models created especially for installations in tall grass

The Hunter I-20 Ultra offers a taller pop-up height: the 6" pop-up designed for maximum versatility in higher cut turf. A taller cutting height is becoming the accepted standard for maintaining turf because with the taller height comes the enhanced ability to weather drought conditions. With this capability, the turf can go for longer periods of time without irrigation.

Some of the cooler season grasses, such as

Tall Fescue, may grow as much as 2" between mowing periods. Maintaining this turf at a taller mow height (3" to 32") would be a problem when using shorter rotors because within the mow period the grass may grow to 52" high. This would be a full 12" above the nozzle outlet, effectively blocking the water stream.

Eliminate Wet Spots with FloStop

Temporarily turn off a rotor to reduce excess moisture due to shade or soil composition.

Superior Coverage –

Across the Range…

8 standard and 4 low angle nozzles

With every sprinkler in the

I-20 Ultra rotor group, twelve nozzles are included on one rack—FREE! 8 standard

– (25' trajectory) and 4 low angle

(13' trajectory) nozzles. Totally interchangeable and recyclable, these twelve nozzles provide maximum lexibility for any irrigation system application.

Only the I-20 Ultra provides excellent coverage close to the sprinkler as well as throughout its entire distance of throw. The exceptional performance of I-20 Ultra nozzles guarantees uniform results – with no wet or dry spots in all head-to-head spacing installations from 25' to 47' (7,6 to 14,3 m). Plus, with the built-in nozzle removal tab, the nozzles are readily interchanged and adjusted, allowing the installer to easily ine tune the system to meet ield conditions. If wind, slopes or low hanging tree branches are concerns, use the low angle nozzles.

If there is a need to water a smaller area, request the I-20 Ultra 18' or 25' nozzles from your distributor for precise coverage in those tough circumstances.

Short Distance Nozzles…

The coverage range of a spray with the beneits of a commercial-grade rotor

The I-20 Ultra Short

Distance Nozzles

(p/n 466100) have been uniquely crafted for turf areas needing a smaller radius.

This “six pack” of nozzles includes three 18'

(5,5 m) distance nozzles (at 50 PSI) (3.4 bars) with low rates of 0.50, 1.0, 2.0 GPM (1,89;

3,79; 7,57 lpm) and three 25' (7,6 m) distance nozzles (at 50 PSI) (3.4 bars) with low rates of 0.75, 1.5, 3.0 GPM (2,84; 5,68; 11,36 lpm).

These nozzles will precisely irrigate the area you want without wasting water beyond your desired throw. This nozzle rack is available at your distributor as a separate part to the

I-20 Ultra rotor.

High Flow Nozzles…

Higher precipitation rates are achieved when needed

For systems that need to deliver water at higher than normal low rates, the I-20 Ultra

High Flow Nozzles

(p/n 444800) are the answer. The nozzle tree includes two (#10, #13) standard angle nozzles and two (#6 LA, #8 LA) low angle nozzles with lows of 4.2 to 14.8 GPM

Square Top Designed Nozzles…

Self aligning makes nozzle installation easy

The new square top design makes the nozzle easy to install or change because the nozzle aligns itself automatically.

With perfect alignment every time, the nozzle set screw will always screw in easily.

Proven, Long-Life Water Lubricated

Gear Drive…

The #1 reliable gear drive system

A rotor needs to rotate – every time! Choose the one that will ensure you with reliability and time proven optimum performance. First introduced over 20 years ago and still being continuously improved,

Hunterʼs water lubricated gear drive system is

#1 in the industry. Since that original commitment to irrigation, Hunter Industries has been improving the best light commercial rotor in the business.

Robust Construction…

Stands up to heavy equipment and foot trafic

The extremely tough body cap with ribbed reinforcement provides exceptional strength, making heavy equipment and foot trafic no problem for this commercial grade rotor. Because of this rugged construction, the I-20 Ultra is vandal resistant.

Advanced Wiper Seal…

The most reliable and time proven pressure activated riser seal

The I-20 Ultra includes a heavy-duty pressure activated riser seal that has been designed for long life under harsh, gritty conditions. A special chemical agent is incorporated into the rubber to keep microbial action from damaging the seal. The surface area of the seal, which is in contact with the riser shaft, is large enough to stop all low-by, but small enough to keep debris from lodging between the seal and the riser shaft. The I-20 Ultra riser seal has the capability to be easily lowered on the riser shaft for cleaning, or replacement thus keeping the beneits of a no low-by rotor.

5-Year Warranty…

A product thatʼs sure to endure

Combine the continuously improved geardrive system (backed by over two decades of proven reliability) and the Ultra sturdy construction of this commercial grade industry leading rotor, and youʼll see why itʼs easy for

Hunter to provide a full 5-year warranty on the

I-20 Ultra.

Date Coding…

The easy way to identify exactly when your rotor was manufactured

All the I-20 Ultra Series rotors have the manufactured date code stamped on the side of the nozzle turret. The date code is stamped with a four digit code – the irst two digits representing the year, the last two digits indicating the month (e.g., 03 08 stands for August 2003).

40˚ to 360˚ Adjustable Arc or Full Circle

Versions…

For fastest, hassle-free adjustment, wet or dry, up or down

The I-20 Ultra Adjustable Arc Rotor is the all-in-one sprinkler because of its reversing full circle and part-circle operation in one unit.

With its 40˚ to 360˚ Adjustable Arc, most odd shaped areas can be irrigated with a quick turn of the Hunter wrench. The I-20 Ultra can be

Optional Stainless Steel Riser…

Extra heavy-duty protection

The optional stainless steel riser sleeve not only adds strength to the sprinkler, but also protects the riser and seal from excessive wear and tear. Abrasive sandy soils may score plastic risers and seals causing them to leak prematurely or cause riser

“stick-ups”. Even when challenged by adverse soil conditions like these, the stainless steel riser helps to add years to the rotorʼs life.

Factory Installed Nozzles…

Convenience for large projects

Hunter is always looking for ways to help the installer be more cost effective. The I-20 Ultra can be ordered with factory installed nozzles to reduce the amount of time needed to install sprinklers. This convenience on large projects translates to a lot of time potentially saved on the job.

Quick Check Arc/Fast Forward…

Quick veriication of arc stop points

The I-20 Ultra allows the user to check the right and left arc stops without affecting the original settings. The ability to manually move the arc in a fast forward manner allows the installer to set the sprinkler arc more rapidly.

Where the arc stops will be very close to the same point as when the rotor is operating under water pressure.

Drain Check Valve for up to 10'

Elevation Change…

Saves water, reduces liability

A drain check valve is a standard feature on all I-20 Ultra models.

The check valve is designed to hold without leakage, the equivalent of 10' (3 m) of water pressure.

Stopping low head drainage eliminates

No wasteful lowhead drainage

washouts and wasted water, and may also prevent accidents from occurring and pests from showing up. Also, due to water remaining in the pipes, installers may beneit from the reduction of potential “water hammer” surge damage.

3-Spring Reversing Mechanism…

Reliability when itʼs needed

The three springs in the I-20 Ultra reversing mechanism create a very sharp, crisp reverse trip action generating precise control of the arc stops. Just about every adjustable rotor on the market has a 2-spring reversing mechanism that results in a somewhat soft, non-precise reversing trip, which tends to creep over time.

Heavy Duty Body Cap Threads…

Super coarse for super performance

Muddy soil? The heavy duty threads on the

I-20 Ultra are designed to take it. Adverse soil conditions wonʼt interfere with the threading process with these super coarse threads.

Need to service the ilter screen? Just a few quick turns and the riser is out with the I-20 Ultra.

“Jar Top” Convenience…

Simpliies servicing

If cleaning the screen becomes necessary, simply unscrew the cap — the internals will come out as one piece, not in multiple parts that end up getting lost or broken. And there are no special tools or training classes needed to take apart the I-20 Ultra.

Large Dirty Water Filter Screen…

Puts an end to clogging

If dirty water is in use, the large ilter screen helps prevent clogging of the nozzle.

The screen is easily serviced without removing the sprinkler body from the line.

Optional Purple Rubber Cover...

Identiies non-potable water

Donʼt leave the identiication of your systemʼs water source up to question.

The I-20 Ultra permanent rubber cover is also available in purple — denoting the use of reclaimed water.

Shrub Staking Kit…

Secure installation of shrub rotors on slopes or in shrub areas

The Hunter Shrub Staking Kit allows contractors to install the PGS and I-10 rotor quickly and easily on slopes and in shrub beds.
