Working Principle

The working principle of a manual spray gun is to atomize liquid paint into fine mist droplets using compressed air, which are then directed by the airflow onto the surface of the target object. More specifically, the spray gun is connected to a pressure source (such as a pressure tank, pot, or pump), which supplies the necessary air pressure to atomize the paint at the nozzle, allowing it to be sprayed onto the surface through controlled airflow.

Advantages

Timeliness: Manual spray guns are ready to use at any time. They are easy to operate and require minimal setup.

Compact and Aesthetic Design: With a small footprint and user-friendly design, they are convenient and space-saving.
High Efficiency: The spraying process is highly efficient, capable of achieving 3 to 4 times the productivity of manual brushing.

Types

Manual spray guns can be categorized based on their working principle into the following types: gravity feed, pressure feed, and siphon feed. They can also be classified by function into electrostatic spray guns and high-pressure spray guns. Electrostatic spray guns utilize electrostatic principles for improved atomization and higher efficiency.
