Flat Fan Nozzles
The flat fan pattern is effectively a line of spray. The impact of this spray is high when compared to full or hollow cone spray patterns, but not as high a solid stream nozzle.
The droplet sizes produced by this type of nozzle are larger than cone nozzles, although very fine droplet flat fans can be produced by some air atomising flat fan nozzles.
In order for a flat fan nozzle to cover an area some kind of relative motion is required. Commonly this motion is provided by a conveyor moving product under a series of flat fan sprays. Alternatively the nozzle itself can be in motion to provide complete coverage.
