Hunter i-90 Rotary Sprinkler Installation Guide

Hunter i-90 Rotary Sprinkler

The industry’s longest-distance rotary sprinkler is specifically designed for parks, sports fields, and public areas. With a radius up to 29 meters from a single sprinkler, the I-90 boasts a coverage area no other commercial sprinkler can deliver. Yet, its reduced-size diameter and cushioned rubber cover make it the perfect choice for parks and wide-open lawn areas, as well as the perimeter watering of athletic fields and horse arenas. The rotor is also easy to service, with a “jar-top” body cap that allows quick access to the filter screen and check valve with no extra pieces, parts, or tools required. The I-90 is offered in two models–a full-circle opposing-nozzle version or an adjustable arc model–each with color-coded nozzles that can be field-changed to match the specific needs of your site.

The Ideal Choice for Parks and Large Spaces

If you’re looking for the smallest number of sprinklers to cover the greatest amount of turf, the I-90 is the choice. For sports fields that feature a substantial amount of turf–such as those for soccer, football, or lacrosse–the I-90 gives you the ability to place just a few rotors in place and receive complete coverage from perimeter areas. After all, the I-90 is designed to effectively irrigate turf areas that require a sprinkler that distributes water well in excess of 30 meters. Plus, its small exposed surface and rubber cover make it the safe choice as well.

Nozzle Performance Data

I-90-36V Nozzle Performance Data – Metric

Note: To ensure optimum nozzle performance, the rotor should be be operated in the “Recommended pressure range”. The sprinkler will work normally when used in the “Operating pressure range”, but nozzle performance may be reduced. Data represents test results in zero wind. Adjust for local conditions. Performance data are derived from tests that conform to ASAE Standard S398.1. See Hunter Irrigation Products Catalog for complete ASAE Certification Statement.

I-90-ADV Nozzle Performance Data – Metric

* Factory-installed nozzle
** Preliminary performance data
Note: All precipitation rates are calculated for 180-degree operation. For the precipitation rate for a 360-degree sprinkler, divide by 2.
