In Bete fan nozzles, the liquid is forced through a relatively small, elliptical orifice to provide a thin, flat sheet of spray which covers a narrow area. They are particularly effective in application such as washing or descaling where the nozzles are fixed and the item to be sprayed passes by.
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.
