What is a key characteristic of the flat fan nozzle?

The key characteristic of the flat fan nozzle is that it has a fan angle ranging from 50 to 160°. This specific design allows for a wide and even distribution of the spray, making it particularly useful for applying pesticides, herbicides, and sometimes fertilizers over large areas. The fan shape enables coverage in a swath, which is ideal for treating large or flat surfaces, such as agricultural fields or lawns.

The versatility in the fan angle also means that applicators can adjust the nozzle to achieve different spray patterns depending on the specific application needs, which can be critical for ensuring even coverage while minimizing drift and maximizing efficacy. Therefore, the range of spray angles is essential in determining how effectively the flat fan nozzle can meet various requirements in pesticide application practices.
