Why is the air so dry in your scuba tank?
The air in your scuba tank is as dry as the Sahara, the moisture having been removed from it in order to protect the inside of your tank and regulator from corrosion. Each incoming breath of dry air picks up moisture from your throat and lungs and carries it out when you exhale, so every breath represents a loss of water.
How much? Not as much as you’d guess from the cotton-mouth feeling that results. On a four-tank day you’ll breathe about 260 cubic feet of dry air (assuming 80-cubic-foot tanks–actually 77.4–and a minimum pressure of 500 psi). The maximum amount of water that much air could have contained (at 100 percent humidity, 86F) is about one cup. In fact, you probably lose less. Research reported in the journal Respiration Physiology suggests that most of this water loss occurs in the first 15 minutes when your upper respiratory tract dries out. Regulators that trap moisture in the second stage to moisten incoming air lessen, but probably don’t entirely prevent, the drying effect of breathing tank air.
