I do know from my use of refrigeration-based de-humidifiers that there's a lot of water in air. So much so that sometimes I add the de-humidifier's tank contents to my washing machine runs to soften the water for the sake of the soap function. My point - a lot of water can be pulled out of the air.
In chemistry experiments at school air involved in the experiment was pulled through a U-Tube containing Sodium Hydroxide powder so that it was completely dry, but that method would invite a disaster in an airgunning situation involving aluminium.
How do the airgun and dive bottle dryers work?
