Yes indeed. 1 atmosphere air. But in terms of flow rate, it makes no difference. You inhale by volume, not by oxygen content, so if you inhale 1 liter at the surface, you'll inhale 1 liter at 100 feet. You'll be getting 4 times as much gas, including 4 times as much oxygen, as you would on the surface. So your kg/min will be higher, but your liters/min will be the same. That's my understanding anyway, from drilling my brother when he went through all those damn PADI certs. >Getting an airfill at DDWP is about $5.
