Fluid Dynamics Pros and Cons of Side-Cup, Gravity-Feed, and Siphon-Feed Airbrushes

When selecting and evaluating a pneumatic airbrush (Airbrush), most users intuitively focus on “paint cup capacity” or “grip feel.” However, in mold development and precision CNC turning/milling environments, the feed system is essentially a mechanical equilibrium system of fluid transfer and Venturi-effect negative pressure. The feed structure directly determines: With nearly 30 years of experience […]
