Des-Case Extended Series Desiccant Breathers

Desiccant Breather DC-EX-3

The Des-Case Desiccant Breather DC-EX-3 combines the trusted materials and design of our Standard breathers with the check-valves of our VentGuard™ and HydroGuard® breathers, plus a new oil mist reducing feature, higher air flows and more than double the desiccant! These high airflow, long-lasting desiccant breathers are ideal for tank farms and large or remote applications.


  • Removes moisture in the headspace of equipment
  • Eliminates rust-forming condensation
  • Prevents sludge deposits and water-contaminated oil
  • Prevents contamination ingress
  • Provides longer lubricant life
  • Reduces wear and tear on equipment, prolongs life

As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate, and the color-indicating silica gel extracts moisture. When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere.

Additionally, the breather is outfitted with a resilient nylon standpipe and polypropylene oil mist reducer to allow oil mist to coalesce and drain back into the reservoir, rather than compromising the desiccant. Six high-quality umbrella check-valves are located underneath the unit to isolate equipment from ambient conditions, prolonging breather life and protecting system integrity.

SEEING PINK? As shown above. A pink breather in fact means it has done its job keeping moisture out of your lubricants. In Conclusion it is time to replace the breather with a new one.
