In a siphon feed airbrush, the paint is pulled up through a tube by the airflow created by the airbrush compressor. The paint is then mixed with air and sprayed onto the surface being painted. This type of airbrush is commonly used in applications that require the use of larger amounts of paint, such as painting cars or other large surfaces.

Siphon feed airbrushes are typically less expensive than their gravity feed counterparts, and they are also easier to clean and maintain. However, they may not provide the same level of control and precision as gravity feed airbrushes, especially when working with smaller details.
