High pressure airless spraying, also known as airless spraying, uses a high-pressure plunger pump to directly pressurize the paint, forming high-pressure paint that is sprayed onto the surface of the object (wall or wooden surface) to form an atomized airflow.

Compared to air spraying, airless spraying produces a uniform and particle free paint surface that does not scatter, pollute the environment, or cause waste.

Due to its isolation from the air, the paint is dry and clean, and airless spraying can be used for the construction of high viscosity paint with clear edges. It can even be used for some spraying projects with boundary requirements.

Depending on the type of machinery, airless spraying can be divided into various types such as pneumatic, electric, internal combustion, etc.
