Another weird music video for you. They had a cool website with lots of great stuff, but alas it's gone now, replaced by stupid Facebook. I despise Facebook, I can't wait for the day when they go the way of MySpace.
On the left is my excellent Preval vFan airbrush that Home Depot gave me to evaluate. You can see the hose has a standard 1/4" male QD connector installed. On the right is a pressure regulator, with a standard female QD connector on the outlet side, and a scuba-to-NPT adapter on the inlet side. Plug that into an inflator hose on a scuba regulator, and set your output pressure on the inline regulator.
