What happens if a compressed-air sprayer is operated at excessive pressure?

Operating a compressed-air sprayer at excessive pressure primarily results in the production of too fine droplets. When the pressure is increased, the force with which the liquid is expelled also rises, leading to smaller droplet formation. Fine droplets can enhance the ability of the pesticide to drift, which may be beneficial in reaching difficult surfaces but can also lead to undesirable consequences, such as increased evaporation or drift off-target, reducing the efficiency and effectiveness of the application.

In contrast, options that suggest larger droplets or improved coverage would typically be associated with lower pressures, where the product can be applied more uniformly without the risks associated with fine droplet formation. Similarly, excessive pressure does not inherently reduce clogging but may actually contribute to it if the fine droplets do not exit the sprayer uniformly or if the pressure causes wear and tear on the equipment over time.
