Flat fan spray nozzles

Flat fan spray nozzles most often create a high impact spray, with droplets that are relatively larger compared to other types of spray nozzles.

The flat fan nozzle is very effective for various flushing, rinsing and washing processes, but is also used to spray liquid over products and materials on conveyor belts. The flat fan nozzle creates a spray shaped like a straight band over the surface.

Flatstråledysan skaåar en spray som är formad som ett rakt streck. Flatstråledysans droppar är relativt stora jämfört med andra dysor och sprayen är ofta kompakt och kraftig.

AFF flat fan nozzle is used for water mist and offshore fire suppression, with FM Approval certification. The nozzle creates a coarse atomisation with medium impact spray. The spray angle is extra wide, 145°.

Various types of flat fan nozzles

There are two different types of flat fan nozzles - axial or deflector. The axial flat fan nozzle creates a thin, flat spray that gradually widens as it moves outward. The deflector nozzle flat fan spray is deflected off an external surface, and produces an extra-wide fan spray pattern.

Axiell flatstråledysa skapar en spray  som smalnar av mot ytterkanterna av sprayen.

Axial flat fan nozzle

  • Uniform distribution with tapered edges

 

Deflektor flatstråledysa skapar en spray med extra bred sprayvinkel.

Deflector flat fan nozzle

  • The spray is deflected off an external surface and creates an extra-wide fan spray pattern

Choose the right spray nozzle for an optimised spray process

Each type of spray nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and solution.

  • What is the function of the spray nozzle and the spray process?

    The first step when choosing the right spray nozzle is to define the function and application of the spray process, such as cooling a gas, washing a tank or flushing a conveyor belt. Type of spray nozzle, thus also spray pattern and droplet size, are important to consider in order to optimise the spray process.

  • Which droplet size is most suitable for the spray process?

    Droplet size is often critical in optimising a spray process. Many processes, such as gas cooling and gas scrubbing, depend on exposing the maximum total liquid surface area. The liquid then needs to be distributed in a large number of small droplets to create as much total surface area as possible. Other spray processes ...

  • What surface should the spray cover? How should the nozzle be positioned?

    The position of the nozzle over the target (D) and the area to be covered by the spray (B) are important to know in order to choose the right spray angle (A). The spray angle is measured near the nozzle orifice and the droplets are immediately affected by external forces such as gravity, air and gas flow.

  • Desired flow rate? Available pressure?

    Desired volume flow depends on the specific spray process. Most spray processes have general rules of thumb for flow ranges, but in many cases on-site testing is needed to achieve the right results.

  • What type of liquid is used in the spray process?

    A liquid's specific gravity, viscosity and the presence of particles affect the spray characteristics of the nozzle.
