Van Air Systems Activated Alumina Desiccant is a porous form of aluminum oxide and is designed with a high surface area that adsorbs vapors without any change in form. In compressed air and gas drying applications, activated alumina is able to achieve dew points -40°F to -100°F depending on the dryer.

The most commonly used activated alumina bead is the 1/8 inch size. The 1/4 inch size works well as a pre-bed for supporting large desiccant beds or as a buffer for silica gel beds. When pressure drops and surface area requirements are smaller, the 3/16 inch bead size is ideal.
