Activated alumina is an aluminum oxide bead with an extremely porous structure and high surface area-to-mass ratio. Activated alumina 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. In compressed air desiccant dryers, a 1/8" (2-5 mm) activated alumina bead is most commonly used. Activated alumina is also used as a selective adsorbent, for example of fluoride in water purification applications.| Model | Activated Alumina | |||||
