The flat fan spray nozzles can be used in a wide range of spray applications. Flat fan nozzles cover a fan-shaped area on a single plane and are most appropriately used in a stationary position on a conveyor when the target moves through the spray or when the spray itself is independently moved over the target, such as on a wand. Most flat fans have a parabolic distribution, meaning the flow is heavier towards the center of the spray than the edges. This means the nozzles should overlap their coverages on a spray header to provide an even distribution of fluid over the entire spray target. Typical applications for flat fans include cleaning, coating, cooling, lubricating, rinsing, parts washing, high pressure cleaning, surface treatment, printed circuit board etching, degreasing, phosphating, and foam control. The flat fan line includes threaded nozzles, tip nozzles, deflector nozzles, ball-type nozzles for easier directional spraying, clip-on nozzles which clamp directly to a header pipe, high impact nozzles, and high pressure nozzles.
