What is the impact of a dirty air nozzle on paint application?

A dirty air nozzle can significantly impact paint application by causing uneven spray patterns. When the nozzle is clogged or coated with debris, it restricts the airflow, which disrupts the normal spray pattern that is essential for consistent coverage. This can lead to problems such as blotchy finishes or areas where the paint does not adhere properly.

In contrast, a clean nozzle promotes proper airflow and allows for an even distribution of paint, helping to achieve a smooth and uniform finish. It also enhances paint adhesion since the properly atomized paint will settle evenly onto the surface being painted. High-quality results in painting depend heavily on the equipment being in optimal condition, including the air nozzle.
