Flat Fan Spray 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.
Design variants flat fan nozzles
There are three common designs of flat fan nozzle; elliptical orifice, deflection and air atomising. 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.
Typical applications of flat fan nozzles
Examples of common applications would include:
Cleaning products on conveyor production lines
Coating products on conveyors
