Airless nozzles are a commonly used type of nozzle in spray equipment. They atomize paint directly under high pressure, instead of using compressed air. The design and working principle of airless nozzles give them significant advantages over other types of nozzles in some applications.

Working Principle

High-Pressure Atomization

Airless nozzles pressurize the paint to extremely high levels (usually 2000-3000 PSI, or even higher) and then eject it through a very small nozzle aperture. The paint rapidly disperses and atomizes as it leaves the nozzle.

Uniform Coating:

The high-pressure atomization process produces very fine paint particles, which help to form a smoother, more uniform coating.

Small Aperture

The aperture of an airless nozzle is usually small, which helps to produce a finer spray.

Nozzle Model and Film Thickness

For nozzles with the same spray width but different diameters, the thickness of the film sprayed by the larger diameter nozzle is considered thicker.
