High-Uniformity Nozzles | FCI Nozzles | Full Coverage Irrigation®

Maximizing Sprinkler Irrigation Efficiency

Our Patented Orifice: Impact rotary sprinklers have traditionally relied on high water pressure alone to achieve an acceptable level of water uniformity. The FCI nozzle uses our time proven stainless steel orifice plate to precisely strip just the right amount of water from the outside of the stream creating a "curtain" of water effect.

This curtain of water optimizes the sprinkler profile at both low and high pressures, falling to the ground in a much more uniform and controlled pattern than is possible with standard straight bore nozzles.

Our Exclusive Vane: 

Brass impact sprinklers are incredibly reliable, but have always been plagued with imperfect water passageways, resulting in a turbulent flow of water. Turbulence varies from sprinkler to sprinkler causing uneven sprinkler performance and bad uniformity.

The truth is, maximum uniformity can only be achieved when sprinkler turbulence is eliminated. To remove turbulence, each FCI nozzle is fitted with our exclusive straightening vane. The turbulent free flow is then mechanically altered by the FCI orifice plate, delivering the highest possible uniformity.

What are the advantages of retrofitting my sprinklers with the FCI Nozzle?

  • Maximum possible water uniformity on existing spacings at both low and high pressures
  • Higher yields
    Stainless steel orifice will outlast brass or plastic nozzles
  • Larger orifice opening than straight bore nozzles means less plugging
  • Improved crop cooling in desert regions
  • Clog resistant straightening vane



In 2011, DM Camp & Sons, a large vegetable, nut and grape grower in the southern San Joaquin Valley became interested in retrofitting their impact sprinklers with the newest generation of FCI low pressure sprinkler nozzles. Company president Edwin Camp not only wanted the new nozzles to maximize the water uniformity of his sprinkler system to save water and increase yields, but also to lower his pumping costs by operating the sprinklers at reduced pressure.

After testing the FCI nozzles in the field and independently at the Center for Irrigation Technology (CIT), Camp concluded that the FCI nozzles will deliver the expected performance and ordered 80,000 nozzles to retrofit a good portion of his Weather Tec 10-20 sprinklers used to irrigate vegetables. FCI low pressure nozzles are rebated by PG&E up to $1.15 per nozzle which guarantees a very fast payback on investment to qualified growers.

“We’re running almost all of these at a psi of 35. All are working well and we received a full rebate from PG&E. Very good results. You have a good product. Thanks for the help.”
