What is the primary function of filter screens and strainers in a sprayer?

The primary function of filter screens and strainers in a sprayer is to protect the pumps and prevent clogged nozzles. By filtering out larger particles and debris from the liquid being sprayed, they ensure that the operational components of the sprayer, such as the pumps and nozzles, remain unobstructed. This is essential for maintaining the efficiency and effectiveness of the sprayer. Clogged nozzles can lead to uneven application of materials, reduced pressure, and possibly damage to the sprayer itself. Therefore, the presence of these filtration devices is crucial for ensuring that the sprayer operates smoothly and delivers the intended results.

The other options do not accurately represent the primary function; for example, while aesthetics might play a role in product design, it is not a functional purpose. Increasing pressure is more related to the sprayer's design and operation rather than the function of filters. Lastly, while facilitating easy cleaning could be a benefit of having these components, it is not their main role.
