An illustration of airless spraying atomisation

What is airless spraying?

In an airless system, fluid is pumped under high pressure through a spray tip. Instead of compressed air, the fluid itself is pressurised and the fluid becomes atomised as it passes through the spray tip.

The tip size and fluid pressure is what determines the material flow rate. The tip also creates the fan pattern. In contrast, air spray systems inject compressed air into the fluid stream of paint to achieve atomisation.
