Protect Your Filaments & Equipment from Moisture

About this item

Wisesorb Activated Alumina Desiccant, 3.4 kg (7.5 LBS), provides superior moisture control for critical applications like filament drying and compressed air systems. Imported from authorized US retailers, this reusable desiccant offers high absorption capacity, capable of holding over 30% of its weight in water vapor. Its stable physical and chemical characteristics ensure reliable performance even in demanding environments. Get yours delivered to India with all duties and GST included, via ExpressBox tracked shipping within 12-14 days.

This activated alumina features a highly porous structure with a large surface area, making it exceptionally effective at drying air and gases. It can achieve dew points as low as -100°F/-73℃, making it suitable for deep drying applications under pressure. The 3-5mm beads are designed for optimal performance in various drying systems, including heated and pressure swing dryers. Unlike single-use desiccants, Wisesorb Activated Alumina is fully regenerable, offering a cost-effective and sustainable solution for moisture management.

For optimal performance, place the activated alumina in a watertight container within your system. To regenerate, simply heat the beads in an oven at 200°C-250°C for 8 hours. This process restores its moisture-absorbing capabilities, allowing for repeated use. While local alternatives may offer lower initial costs, Wisesorb provides verified quality and performance for sensitive applications, ensuring your filaments remain dry and your systems operate efficiently.

Key Features

  • Activated Alumina — utilize premium quality raw material with an extremely porous structure and high surface area-to-mass ratio, high strength against crushing and very stable physical and chemical characteristics, even in high temperature and corrosive environments. At 77℉/25℃, RH90%, it can absorb more than 30% of its weight in water vapor. Each bead is 3 – 5mm in size.
  • Activated Alumina — which has excellent porosity creating tortuous paths and extended surface area can be used in both heated and pressure swing dryers. It has stable physical and chemical characteristics, even in high temperature and corrosive environments.
  • Activated alumina — has a wide variety of applications, including compressed air and gas drying. In compressed air and gas drying applications, activated alumina can achieve dew points -100°F/-73℃, depending on the dryer. It is suitable for deep drying under pressure greater than 5kg/cm2.
  • How to Use — Place activated alumina into watertight dryer or container and then place dryer or container into the compress air or gas system. Desiccant Activated Alumina ( Aluminum Oxide) Desiccant is perfect for drying air and most other gases with relatively high humidity.
  • How to Regenerate — 1. Use the dry gas under lower pressure or higher temperature to pass the activated alumina. 2. Use wet gas which is heated or decompressed to pass the activated alumina. The reusable activated alumina beads desiccant dehumidifier can be reactivated by placing into the oven for 8 hours at 200°C-250°C (do not over 250°C).

Why choose this product

Engineered for Precision Moisture Control

Wisesorb Activated Alumina is crafted from premium raw materials, boasting an extremely porous structure and high surface area. This design ensures superior moisture absorption, critical for applications where humidity can degrade materials like 3D printing filaments. Unlike generic desiccants, its high strength against crushing and stable characteristics guarantee reliable performance, even in demanding conditions. Imported directly from authorized US retailers, each batch is factory-sealed for guaranteed quality. This imported desiccant offers a performance edge over many locally available options, ensuring your sensitive materials remain protected from moisture damage.

Ideal for 3D Printing & Industrial Use

This desiccant is perfect for 3D printing enthusiasts needing to keep filament dry for optimal print quality. It's also highly effective for industrial applications like compressed air drying, achieving very low dew points. If you require consistent, high-performance moisture removal for sensitive materials or industrial processes, Wisesorb is your choice. Those seeking a basic, low-capacity moisture absorber for small, non-critical spaces might find simpler, locally available options sufficient, but for demanding tasks, this specialized desiccant is unmatched.

How to use

  • Prepare for Use — Place the Wisesorb Activated Alumina beads into a watertight container or dryer unit. Ensure the container is suitable for the intended application, such as a filament storage box or an air system dryer.
  • Position and Absorb — Place the container with the desiccant into the environment requiring moisture control. For filament, place it with the spools in a sealed bag or box. For air systems, integrate the dryer unit into the compressed air line.
  • Regenerate When Needed — When the desiccant's moisture absorption capacity decreases, regenerate by spreading the beads on a tray and heating in an oven at 200°C-250°C for approximately 8 hours. Allow to cool before reuse.

FAQ, See What Others Asked

What is activated alumina and how does it work?
Activated alumina is a highly porous material with a large surface area, used as a desiccant to absorb moisture from air and gases. It works by trapping water vapor within its structure. Wisesorb's activated alumina can absorb over 30% of its weight in water and can be regenerated for repeated use, making it effective for filament drying and industrial applications.
How do I regenerate Wisesorb Activated Alumina?
To regenerate the Wisesorb Activated Alumina, place the beads into an oven and heat them for 8 hours at a temperature between 200°C and 250°C. Ensure the temperature does not exceed 250°C. This process restores its moisture-absorbing capacity, allowing for continuous reuse.
What is the best way to use activated alumina for 3D printing filament?
For 3D printing filament, place the activated alumina beads into a watertight container or dryer along with your filament spools. This will effectively absorb ambient moisture, preventing filament from becoming wet and ensuring optimal print quality. The 7.5 LB pack provides ample desiccant for multiple spools or larger storage solutions.
Can activated alumina be used for compressed air systems in India?
Yes, activated alumina is highly effective for drying compressed air and gases, capable of achieving very low dew points (-100°F/-73℃). It's suitable for deep drying under pressure. Wisesorb's product is ideal for industrial or professional use in India where dry air is critical for equipment performance and longevity.
How does Wisesorb Activated Alumina compare to local dehumidifier options?
Wisesorb Activated Alumina offers a specialized, high-performance desiccant solution for critical applications like filament drying and industrial gas drying. While local dehumidifier machines are designed for room-level humidity control, this activated alumina provides targeted moisture absorption with high capacity and regenerability. For specific needs requiring extreme dryness, Wisesorb's imported quality provides a reliable advantage over general-purpose local alternatives.
