A flat fan spray nozzle produces a narrow, straight spray with tapered edges, which allows for overlapping of spray patterns. This type of spray is often used in applications where the target is moving past the spray, such as on a conveyor or in a car wash. Flat fan sprays concentrate the impact of the spray in a small area, resulting in higher impact and more effective cleaning. Flat fan sprays are commonly used in parts cleaning, metal washing, foam control, asphalt spraying, car washes, and dishwashers.
