Which nozzle type is characterized by a narrow oval spray pattern?

The regular flat fan nozzle is characterized by a narrow oval spray pattern due to its design, which directs the liquid through a flat, fan-shaped opening. This specific configuration allows for a more concentrated application of pesticides, making it ideal for tasks requiring precision. By creating a narrow spray, it minimizes overlap and ensures that the product is applied exactly where needed, which is especially important in forestry pest control to avoid non-target areas.

In contrast, the other nozzle types have different spray characteristics. The even flat fan nozzle produces a more uniform spray pattern suitable for broader applications. The hollow cone nozzle creates a conical spray pattern that disperses droplets more widely, making it useful for applications that need coverage of larger areas or for better penetration into foliage. Meanwhile, the flooding fan nozzle typically generates a wider spray pattern designed for applications that require extensive coverage, making it less suitable for precision work where a narrow pattern is needed.
