Product Description
For high-volume desiccant replacement and industrial drying applications, this Made in USA 1/4″ (6.4 mm) Activated Alumina Desiccant is supplied in a 2,000 lb (907 kg) super sack for efficient handling and loading into large dryer vessels.
Activated alumina is a highly porous aluminum oxide drying media engineered to adsorb moisture from compressed air and gas streams without dissolving or substantially changing form during normal service.
The uniform 1/4″ (6.4 mm) bead size is well suited for compatible systems where larger desiccant media is specified. The material provides a typical 320 m²/g surface area and 0.50 cc/g pore volume, providing extensive internal surface area for moisture adsorption.
At 60% relative humidity, typical moisture adsorption capacity is 22 wt.%. Mechanical properties include a typical 45 lb (20 kg) crush strength, 0.2 wt.% abrasion loss, and 99.6 wt.% attrition retention, helping resist media degradation during handling and repeated dryer operation.
Packaged in a 2,000 lb super sack, this product is an efficient choice for large regenerative dryers, major plant turnarounds, OEM production, and bulk maintenance programs.
Why Choose This Activated Alumina?
Made in the USA
Manufactured domestically for consistent material quality and dependable supply.
2,000 lb Super Sack Packaging
Designed for larger dryer change-outs and high-volume applications where individual 50 lb bags may be impractical.
High Moisture Adsorption Capacity
Typical adsorption capacity of 22 wt.% at 60% RH provides effective moisture removal in compatible air and gas drying systems.
High Surface Area
A typical 320 m²/g surface area and 0.50 cc/g total pore volume provide the porous structure required for effective moisture adsorption.
Durable, Low-Dust Media
Typical 45 lb (20 kg) crush strength, 0.2 wt.% abrasion loss, and 99.6 wt.% attrition retention help reduce media degradation and generation of fines.
Uniform 1/4″ (6.4 mm) Beads
Consistent bead sizing promotes uniform loading and predictable airflow in dryer vessels designed for 1/4″ media.

Replacement / Cross-Reference Information
This activated alumina is intended for industrial drying applications requiring 1/4″ (6.4 mm) activated alumina media and may be suitable for replacement of compatible OEM desiccant products.
Always verify the required desiccant type, bead size, total fill quantity, and dryer manufacturer’s specifications before replacing existing media.
Planning a Large Desiccant Change-Out?
Provide I-CON Solutions with your dryer manufacturer, model number, existing desiccant part number, and required fill quantity, and our compressed-air team can help confirm the appropriate replacement media and quantity.
