What is the primary function of a strainer in spray equipment?

The primary function of a strainer in spray equipment is to prevent clogged nozzles. Strainers are designed to filter out larger particles and debris from liquids before they are sprayed. By doing so, they ensure that the liquid passing through the spray nozzles is free from contaminants that could impede the flow or cause the nozzles to become blocked. This is crucial for maintaining the efficiency and effectiveness of the spray application, as a clogged nozzle can lead to uneven coverage, reduced spray quality, and potentially damage to the equipment.

While maintaining product suspension, controlling pressure, and modifying droplet size are important aspects of spray technology, they are not the primary role of a strainer. Instead, those functions are typically managed by other components of the spray equipment. For instance, product suspension is often maintained by using appropriate agitation methods, pressure control can be achieved through regulators and pumps, and droplet size can be affected by nozzle design or settings, rather than by the strainer itself. Thus, the strainer's main contribution lies specifically in preventing nozzle clogs, ensuring smooth and efficient operation of the spray system.
