What is the purpose of the strainer screen in a nozzle assembly?

The strainer screen in a nozzle assembly serves the critical function of keeping the nozzle tip from clogging. When pesticides or other solutions are applied, they can contain particles or debris that, if not filtered out, may obstruct the nozzle, leading to inconsistent application or even complete failure of the spray system. By effectively trapping these particles, the strainer screen ensures that the fluid passing through the nozzle remains clear, thereby maintaining a consistent flow and optimal performance.

While other functions, like enhancing flow rates or adjusting droplet sizes, are important for the overall performance of a spraying system, they are not the primary role of the strainer screen. The screen does not alter the spread pattern directly; instead, it maintains the nozzle’s effectiveness by preventing blockages, which could impact how the pesticide is applied. This focus on uninterrupted flow is essential for achieving even coverage and effectiveness in pest control applications.
