BETE NFS Stubby Flat Fan Nozzles

BETE Compact Fan Nozzles for Tight Spaces With Low Clearance

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 as a solid stream nozzle. The droplet sizes produced by this type of nozzle are larger than cone nozzles, although some air-atomizing flat fan nozzles can make very fine droplet flat fans.

For a flat fan nozzle to cover an area, some 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 action to provide complete coverage.

The BETE NFS spray nozzle is an elliptical orifice flat fan nozzle. With this typical nozzle design, 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 only partially even. The ends of the spray pattern have less fluid delivered. A series of nozzles with slightly overlapping spray patterns should be built to achieve a thoroughly even spray. Once the level of spray loss at the edges of the pattern is known, this is just a matter of simple trigonometry.

BETE NFS Spray Nozzles Design Features

• Extremely short length for minimum projection and maximum clearance
• Produces a flat fan spray pattern available in a variety of spray angles
• Available in straight (parallel) threads only, NPS and BSPP
• Requires gasket to seal connection

Spray Characteristics of BETE NFS Spray Nozzles

Spray Pattern: Fan

Spray Angle 60° 

How Spray Pattern is Achieved

• A thin flat sheet of liquid is produced when the fluid exits the orifice, and the spray begins to widen and gradually moves outward from the nozzle
