Flat fan nozzles

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.

Design variants flat fan nozzles

There are two common designs of hydraulic flat fan nozzle; elliptical orifice and deflection. Air atomising or pneumatic nozzles can also be used to create flat fans with a very fine droplet size. Detailed information on pneumatic design variants can be found by clicking on the items in the blue menu to the right. For details on air atomising flat fan nozzles please visit the air atomising section of this site.

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.
