Activated Alumina for air & gas drying.

Activated alumina, uses a process called adsorption to dry air and gasses. As the air passes through the alumina, the water molecules become stuck to the alumina. The small passages keep the water, therefore, drying out the air as it passes. If the activated alumina is heated to ~200°C, it will release the water molecules so it can be used over and over.
