What is a sign that the air nozzle might be worn or needs cleaning?

A sputtering or uneven spray is an indication that the air nozzle may be worn or require cleaning. Over time, particles can accumulate in the nozzle or the nozzle itself can degrade, leading to a disruption in the flow of air and paint. As a result, the spray pattern becomes inconsistent, which manifests as sputtering or uneven application. This can adversely affect the quality of the finish, making it essential for painters to routinely check and maintain their equipment, ensuring that the nozzle is clean and functioning properly to achieve the desired results.

In contrast, an even spray pattern would indicate that the nozzle is functioning correctly, while low paint consumption does not directly relate to the condition of the nozzle, but rather to the overall efficiency of the painting process. Consistent spray speed also suggests that the equipment is operating well, without any issues stemming from wear or blockage in the nozzle.
