Activated Alumina

Activated Alumina
Purpose: Drying Air and Most Gases with High Relative Humidities
Bead Sizes: 1/16'', 1/8'', 3/16'', ¼'' (custom sizes available)
Quantity: Large Variety of Sizes

Activated alumina is an excellent all purpose desiccant for drying air and most other gases with high relative humidities. Dewpoints of -100°F can be achieved (depending on dryer). Activated alumina can be used in both heated and heatless / pressure swing dryers.

Activated alumina has: excellent porosity creating tortuous paths and extended surface area; high strength against crushing; and very stable physical and chemical characteristics, even in high temperature and corrosive environments.


  • -100°F dew points obtainable
  • Unaffected by catastrophic liquid water loading
  • Ideal for both heatless and heat regenerated systems
  • Low regeneration temperature 250°F to 500°F


  • Moisture removal at 40%RH: 13.5%/wt
  • Moisture removal at 60%RH: 20%/wt
  • Moisture removal at 100%RH: 40%/wt
  • Crush Strength (lbs): 30 - 70 (Depends on grade)
  • Abrasion Loss (%/wt): <0.1
