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). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B81XLQV2 | | Best Sellers Rank | #11,407 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #61 in Desiccants #93 in Disinfectant Sprays & Liquids #172 in Dehumidifiers | | Brand Name | Wisesorb | | Capacity | 3.4 kg | | Color | Activated Alumina | | Customer Reviews | 4.7 4.7 out of 5 stars (149) | | Included Components | Activated Alumina | | Item Weight | 7.5 pounds | | Manufacturer | Wisesorbent Technology LLC | | Material | Activated Alumina | | Model Name | B0B81XLQV2 | | Model Number | B0B81XLQV2 | | Number of Items | 1 | | Number of Packs | 1 | | Operation Mode | Intermittent | | Other Special Features of the Product | Activated Aluminum, Reusable | | Part Number | 7.5lbAA-1 | | Recommended Uses For Product | Commercial, Residential | ## Product Details - **Brand:** Wisesorb - **Capacity:** 3.4 kg - **Color:** Activated Alumina - **Included Components:** Activated Alumina - **Item Weight:** 7.5 pounds - **Material:** Activated Alumina - **Model Name:** B0B81XLQV2 - **Operation Mode:** Intermittent - **Recommended Uses For Product:** Commercial, Residential - **Special Feature:** Activated Aluminum, Reusable ## Images ![7.5LBS Activated Alumina Desiccant 3D Printer Filament Drying for Storage - Image 1](https://m.media-amazon.com/images/I/614I2jjuKdL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What happens if the desiccant is dried at over 250c? if i have a precise and well controlled oven can it go higher (like 315c)?** A: heating them over the recommended temp will probably not damage them. however heating them to recharge them leaves a smell like burnt metal and mildew. I would not recommend drying it in your kitchen oven. I did and it took several days for that smell to dissipate. I moved a little toaster oven outside my house and I recharge the desiccant in small batches. very effective. ## Frequently Bought Together - Wisesorb 7.5 LBS Activated Alumina, Alumina Desiccant, Reusable Desiccant Dehumidifier - 2 Pack Mini Digital Hygrometer Thermometer Gauge, Indoor Outdoor Temperature Humidity Meter for Greenhouse Humidors Incubators Reptile Terrarium Jars, Fahrenheit (℉) or Celsius(℃) (2) - Powder Shaker with Lid,Stainless Steel Fine Mesh Shaker, for Sifter Cocoa,Cinnamon Powder,Icing Sugar,Chocolate Coffee (Small-12Pcs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/493717244-7-5lbs-activated-alumina-desiccant-3d-printer-filament-drying-storage](https://www.desertcart.lk/products/493717244-7-5lbs-activated-alumina-desiccant-3d-printer-filament-drying-storage) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-24*
