Why do some spray guns require an air dryer and what does it do?

An air dryer is an essential piece of equipment in some spray systems, particularly when working with high-precision tools like an Advanced Low-Volume LVLP spray gun. In this article, we’ll discuss why some spray guns need an air dryer and the role it plays in maintaining optimal spray performance.

Why an Air Dryer is Necessary

Air dryers remove moisture from the compressed air before it reaches the spray gun, which is essential for preventing issues like:

• Moisture contamination in the paint

• Uneven atomization

• Paint defects like streaks or bubbles

What Does an Air Dryer Do?

1. Moisture Removal: The dryer filters out water vapor, preventing it from entering the spray gun and mixing with the paint.
2. Consistent Air Quality: By maintaining a dry, clean airflow, the air dryer ensures stable spray patterns and smoother finishes.
