6 LBS Activated Alumina, Alumina Desiccant Great for Filament Drying, Reusable Dessicant Dehumidifiers Desiccant Moisture Absorber Prevent Wet Filament

Activated Alumina is made from premium raw materials and features an extremely porous structure with a high surface-area-to-mass ratio, strong resistance to crushing, and very stable physical and chemical properties, even under high temperature and corrosive conditions. At 77°F/25°C and RH90%, it can absorb more than 30% of its weight in water vapor. Each bead measures 35mm. Thanks to its excellent porosity, which creates tortuous paths and extended surface area, Activated Alumina works effectively in both heated and pressure swing dryers. It maintains stable physical and chemical characteristics, even in high temperature and corrosive environments.

Activated Alumina serves a wide variety of applications, including compressed air and gas drying. In compressed air and gas drying applications, activated alumina can achieve dew points of -100°F/-73°C, depending on the dryer. It is suitable for deep drying under pressure greater than 5kg/cm².
How to Use: Place activated alumina into a watertight dryer or container, then place the dryer or container into the compressed air or gas system. Desiccant Activated Alumina (Aluminum Oxide) is ideal for drying air and most other gases with relatively high humidity.
How to Regenerate: 1. Use dry gas under lower pressure or higher temperature to pass through the activated alumina. 2. Use wet gas that is heated or decompressed to pass through the activated alumina. The reusable activated alumina beads desiccant dehumidifier can be reactivated by placing it in an oven for 8 hours at 200°C250°C (do not exceed 250°C)
