Breathers & Desiccant

Des-Case logo

Des-Case hygroscopic breathers are unique, patented air filter and water vapor removal systems. They replace the standard breather or ventilation system on virtually all types of industrial equipment that contain hydrocarbons and other non-aqueous fluids. They also prevent contamination of products in storage and process tanks. Many other applications exist, including the reduction of pump down-time for vacuum chambers, adaption to air breathers for off-road vehicles, and more.
