Activated alumina is an aluminum oxide balls with an extremely porous structure and high surface area to mass ratio. Activated aluminium oxide balls has a wide variety of applications, including compressed air and gas drying.
In compressed air and gas drying applications, activated alumina will achieve dew points -40°F to -100°F, depending on the dryer design.
How to choose the right size of activated alumina for your application?
In compressed air desiccant dryers, a 1/8″ (2-5 mm) activated alumina bead is most commonly used. The 1/4″ (5-10 mm) activated alumina bead is typically used as a pre-bed for supporting large desiccant beds or as a buffer for silica gel beds. The 3/16″ (5-10 mm) bead is used when pressure drop and surface area requirements fall between the 1/8″ and 1/4″ material.
