Description

Arcadia Desiccant TA486 Desiccant Basket
Tool-Free Access to Desiccant in Storage and Shipping Containers

The TA486 Desiccant Basket by Arcadia Desiccant is specifically engineered to hold MIL-D-3464 bagged desiccant for use in sealed shipping and storage containers. Available in a range of sizes, each basket can accommodate up to 48 desiccant units, offering flexible moisture control for diverse applications.

The TA486 allows for quick and convenient desiccant replacement without opening the entire container—simply rotate the cover a 1/4 turn to access the interior. Installation is through a 4.015″ (102 mm) diameter hole in the container wall.

Each unit is supplied with a spanner nut, washer, and retained gasket for secure and reliable mounting. Holes in the cover and flange are provided to accommodate safety wire or an inspector’s seal for tamper-evident protection.

Desiccant sizing note: To calculate the number of units of desiccant required, multiply the volume of the container, in cubic feet, by 1.2. Additional desiccant may be required to compensate for dunnage. Source: MIL-STD-2073-1C, Method 50.
