Flat Fan Spray Pattern Nozzles
Description
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 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.
Design variants
There are three common designs of flat fan nozzle. Detailed information on the features and benefits of each design can be found by following the links in the blue menu box to the right hand side of this page.
All the information on all the various designs of flat fan nozzle is summarised in the flat fan nozzle cheat sheet which can be accessed by the orange tab to the right.
