High-pressure airless spraying, also known as airless spraying, refers to the use of high-pressure plunger pumps, directly pressurized paint, forming a high pressure paint, sprayed out of the muzzle of the gun to form an atomized airflow acting on the surface of the object (walls or wood surfaces) of a kind of spraying method.
Compared to airborne spraying, the paint surface is uniform and free of particles. The paint is dry and clean because it is isolated from the air. Airless spraying can be used for high viscosity paints with clear edges, even for some spraying projects with boundary requirements. According to the type of machinery, it is also divided into pneumatic airless sprayers, electric airless sprayers, internal combustion airless sprayers and many other types.
