Quick Answer: How long can you leave air in a dive tank?

What will happen if a scuba tank is filled with air?

When divers need to fill their air tanks, they must do so slowly. This is because as the tank fills, all of the air molecules are being jam packed into a rigid area. Those molecules will start bumping into one another as the pressure builds- creating heat.

Year old air should be fine as long as the tank does not have water in it to aide the corrosion/rust process which can lower the O2 content of the air.

How long can you dive with oxygen?
