The Vallejo Model Air series is formulated for use with airbrushes. They have a base and consistency perfect for airbrushing and should only require minimal thinning. The pigment is ground finer so as not to clog the delicate valves of your airbrush. These colours are strong and vibrant, and are compatible with the entire Vallejo range. If you're airbrushing your miniatures or would like to try, Vallejo Model Air should be your first stop.
