“While both gravity and siphon feed are trusted options for airbrush painting, they have differences,” says Olsen. “Gravity feed airbrushes have a paint holder on top and use both gravity and air pressure, pulling paint down into the airbrush,” she explains. As for siphon feed airbrushes, these have paint holders below and rely on air pressure to pull paint up into the airbrush. When it comes down to it, choosing gravity versus siphon airbrushes depends on the type of work you’re doing. "Gravity airbrushes are great for finer detail brushes and when you’ll be using a lot of different colors," says Vacey. She adds that when working with a larger surface, siphon airbrushes are easier to work with.
