Des-Case Extended Series Desiccant Breathers
Des-Case built the Extended Series Breather in the time-proven design and materials of the Standard Series Breather but with the added benefit of the check-valves from the VentGuard and HydroGuard Breather.
The Extended Series Breather furthermore includes a new oil mist reducing feature as well as a higher airflow and more than double the amount of desiccant. This long-lasting breather is the perfect choice for tank farms as well as large or remote applications.

When the silica turns pink, it is time to replace the unit.
Multiple 3-micron polyester filter elements retain solid particulate when wet, contaminated air moves through the breather unit. At the same time, the blue coloured silica extracts moisture. Finally, the top foam pad absorbs oil mist, preventing it com getting in contact with the silica or entering the atmosphere.
The unit furthermore features a durable nylon standpipe and oil mist reducer in polypropylene, allowing oil mist to coalesce and be led back into the reservoir, thus preventing contamination of the desiccant.
Six umbrella check-valves of high-quality located below the unit isolates the equipment from the general environment, guarantees a long lifespan of the breather unit and protects the system's integrity.
