Drum Desiccant Breathers, also known as Drum Vent Dryers, prevent contamination of chemical products (powders, liquids and semi-solids) in 55-gallon drums during storage and use. AGM’s Drum Vent Dryers are quick and easy to install. The units are reusable — saturated color change silica gel desiccant is easily replaced. Drum Desiccant Breathers can also be filled with orange silica gel (acceptable for use in the European Union), molecular sieve, activated alumina and activated carbon.
