Brand: Hunter Industries SKU: I20-04-SS-R
Product Overview
The Hunter I20-04-SS-R is a reclaimed-water version of the 4-inch I-20 gear-drive rotor. It combines a stainless-steel riser, adjustable 50- to 360-degree arc, standard drain check valve, and reclaimed-water identification for sites supplied by nonpotable irrigation water. The 3/4-inch female NPT inlet connects to a compatible swing joint or threaded fitting, while the 4-inch pop-up height is suited to common turf installations.
Hunter’s I-20 nozzle range allows the irrigation designer to select the required flow, radius, and trajectory. Depending on the installed nozzle and pressure, Hunter publishes a radius range of approximately 17 to 46 feet and flow from 0.36 to 14.8 GPM. Recommended pressure is 25 to 70 PSI, with an operating range of 20 to 100 PSI. Standard nozzles use a 25-degree trajectory, while low-angle nozzles use a 13-degree trajectory.
FloStop control allows the flow through an individual rotor to be shut off while the rest of the zone remains pressurized. Automatic arc return helps restore the set pattern after the turret is forced out of position, and the non-strippable drive mechanism protects the internal gears. The standard check valve holds back up to 10 feet of elevation to help limit low-head drainage.

Compatibility and Installation Notes
- Use only where reclaimed or nonpotable irrigation identification is appropriate for the site.
- Select a compatible Hunter I-20 nozzle for the planned radius, flow, trajectory, and pressure.
- Connect to a compatible 3/4-inch swing joint or threaded fitting.
- Follow local requirements for reclaimed-water identification and system separation.
- Confirm nozzle-package contents if a specific nozzle is required.
Frequently Asked Questions
What does the R designation indicate?
It identifies a factory configuration intended for reclaimed-water systems, including the appropriate nonpotable-water identification.
Can this rotor be used on a potable-water irrigation system?
The rotor can physically operate with suitable irrigation water, but the reclaimed-water identification is intended for nonpotable systems. Use the model that matches the site’s water source and identification requirements.
