BETE NFS Spray Nozzles

Bete NFS Spray Nozzle: Stubby Flat Fan Nozzle

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 atomizing 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.

The Bete NFS Spray nozzle is an elliptical orifice flat fan nozzle. With this common design of nozzle the spray pattern is formed by the exit of the fluid through a shaped orifice. The slightly tapered nature of the flat spray pattern means that spray distribution is not entirely even. The ends of the spray pattern have less fluid delivered. In order to achieve a completely even spray a series of nozzles with slightly overlapping spray patterns should be built. Once the level of spray loss at the edges of the pattern are known this is just a matter of simple trigonometry.
