Can't really tell from the pic, but it looks like a compressor sold under various labels, one of which is 'Studio Compressor', as does the airbrush. IF it is the same one, then it is a relatively high capacity, oil-less piston type, with adjustable pressure regulator, allowing low-pressure running, and works well. Typical retail price in the UK is around £70. It's the one I was going to buy, but was out of stock, so I got a different type, not as good, but good enough.
