Institutional Spray Sprinkler

Rugged, water-saving sprinklers designed for commercial, institutional, and public area applications.

Exceptional strength, innovative features…just the need for high traffic areas. Features like a positive-seal flush cap with an innovative pull-up design that keeps debris out. A high quality, multi-functional, pressure-activated wiper seal. True pressure regulation under a wide range of environmental and pressure conditions to reduce water waste.

An in-stem regulator that acts as a flow control device if the nozzle is removed. A super heavyduty check valve assembly that eliminates the potential liability issues of low head drainage. The most powerful retraction spring in its class. Sounds like a lot in a spray sprinkler? How about one more great feature–just like all other Hunter Institutional Series™ irrigation products, it carries a 5-year warranty.BUILT-IN PRESSURE REGULATION TO RELY ON.

The primary cause of poor performance in irrigation systems is improper pressure. Too low or too high. Elevation changes, improper pipe sizing and excessive inlet pressures at the head all cause it. The Institutional Spray’s built-in pressure regulator solves this problem. The pressure stays at 30 PSI (2 bars). Just where it needs to be.

No misting, no fogging, just regulated pressure. It will take inlet pressures up to 100 PSI (6.9 bars). Did a mower eat a nozzle? No problem, this baby will reduce the flow rate by 70 percent yet still let you find the sprinkler so you can fix it. Built right into the sprinkler, this regulator is ready to go and take charge.
