There are two types of fan nozzle designs: axial and deflector. For axial fan nozzles, 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. The spray pattern is formed for deflector fan nozzles as the liquid exits the orifice; it is deflected off an external surface, creating an extra-wide fan spray pattern.
- Spray widens as it moves outward
- Uniform distribution with tapered edges
- The spray is deflected off an external surface
- Creates an extra-wide fan spray pattern
Examples of Why You Would Choose This Spray Pattern Over Others
Fan nozzles are often the most practical choice for conveyor belt applications. Fan nozzles are your best choice whenever something moves and must be washed, wetted, or coated. Examples are conveyor belt cleaning, suppressing coal dust on a conveyor, and coating molds.
When a high impact force is necessary for either cleaning or other applications, a fan-style nozzle may give you the most optimal results. The SPN series and narrow-angled NF nozzles will provide a large impact force while generating relatively low flow rates.
