Product Description
For large-scale desiccant replacement and industrial drying applications, this Made in USA 3/16″ (4.7 mm) Activated Alumina Desiccant is supplied in a 2,000 lb (907 kg) super sack for efficient handling and bulk dryer maintenance.
Activated alumina is a highly porous aluminum oxide drying media designed to adsorb moisture from compressed air and gas streams. Its combination of moisture adsorption capacity, mechanical durability, and low attrition makes it well suited for regenerative dryer systems and demanding industrial drying applications.
The uniform 3/16″ (4.7 mm) bead size provides dependable packing and airflow characteristics in systems designed for this media size. A typical 320 m²/g surface area and 0.50 cc/g pore volume provide substantial internal surface area for moisture adsorption.
At 60% relative humidity, typical adsorption capacity is 22 wt.%. The material also features a typical 45 lb (20 kg) crush strength, 0.2 wt.% abrasion loss, and 99.6 wt.% attrition retention to help minimize bead degradation and dust generation.
The 2,000 lb super sack provides an efficient solution for large dryer vessels, major maintenance projects, OEM production, and facilities requiring activated alumina in bulk quantities.
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 3/16″ (4.7 mm) Beads
Consistent bead sizing promotes uniform loading and predictable airflow in dryer vessels designed for 3/16″ media.
