Airless spray atomizes, or breaks up fluid into small droplets without the use of compressed air. In an airless system, fluid is pumped under high pressure through a spray tip. The tip size and 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 atomization.
In airless spray, the fast moving high-pressure liquid stream provides the energy necessary to overcome the fluid’s viscosity (resistance to flow) and surface tension (a force that bonds the surface of a liquid together) to form a fine spray.
In the depiction of spray from a gun, high pressure forces fluid through a small nozzle (spray tip). The fluid emerges as a solid stream (sheet) at a high speed. When the solid stream hits the air, it becomes disrupted. This disruption breaks the fluid into fragments initially, then ultimately very small droplets that form the spray pattern.
