How does a pneumatic paint sprayer work? Spray gun, painting tool using compressed air from a nozzle to atomize a liquid into a controlled pattern. The spray nozzle operates by impinging high-velocity turbulent air on the surface of filaments or films of liquid, causing them to collapse to droplets with a wide range of sizes.
How do air paint sprayers work? Within the compressed air sprayer, air jets direct paint to the air nozzle, which atomizes the paint and propels it onto the surface that you’re painting. The fluid nozzle controls the paint’s delivery, while the needle assembly is what causes the paint to flow.
