Des-Case Breathers

Des-Case Desiccant Breathers 

Des-Case have been the go-to for silica gel breathers for decades, collaborating with some of the largest manufacturing companies in the world. It works by simply replacing the standard dust cap or OEM breather cap with your chosen desiccant breather. They provide superior filtration to stand guard against the tiniest particles which could potentially cause harm to your systems and machinery.


Ensure the protection of your lubricants from harmful moisture and particles by using these effective breathers.

The Extended Series of Desiccant Breathers, similar to the VentGuard series, are also equipped with check-valves. This upgraded design ensures that the breather will only function while your equipment is in operation, significantly extending the lifespan of your breather. These filters are perfect for those high airflow remote areas where tanks may be left unattended for long periods of time.

How Des Case Breathers Work

Our breather serves as a replacement for the standard dust cap or OEM breather cap on your equipment, providing effective filtration. As air is drawn into your equipment through the breather, the layered filter elements work to remove particulates, and the desiccant beads efficiently strip away harmful moisture. Whether in service or during shutdown, the desiccant actively attracts moisture from inside your equipment's reservoir, ensuring effective drying of the equipment.
