1/8" Activated Alumina Desiccant Beads for Air Dryers - 50lb Bag

1/8" Activated Alumina Desiccant Beads for Air Dryers & Gas Dehydration

1/8" activated alumina desiccant beads are a high-performance drying solution designed for compressed air systems, gas dehydration, and liquid drying applications. Engineered for superior moisture removal, these spherical desiccant beads provide exceptional adsorption capacity, low dusting, and long service life in both regenerative and non-regenerative dryer systems.

Manufactured using advanced processes using industry-standard materials, these activated alumina beads deliver reliable drying performance across a wide range of operating conditions. Their uniform size and high crush strength ensure efficient airflow, reduced channeling, and consistent dew point control.

Key Features & Benefits

• High Adsorption Capacity: Effectively removes moisture from air, gas, and liquid streams
• Uniform Spherical Beads: Minimizes pressure drop and prevents channeling
• High Crush Strength: Supports taller beds and extended service life
• Low Abrasion Loss: Reduces dusting and protects downstream equipment
• Excellent Regeneration Stability: Performs in both heatless and heated dryer systems
• Long Operational Life: Maintains performance over multiple adsorption cycles

Typical Applications

• Compressed air dryers (heatless & heated regenerative systems)
• Gas dehydration (natural gas, nitrogen, air separation)
• Liquid drying (lubricating oils, refrigerants, transformer oils)
• Acid removal and hydrocarbon purification
• Process stream drying and contaminant removal
