Des-Case HydroGuard® Desiccant Breathers
Des-Case designed the HydroGuard Breather with the capability to obtain as close to a sealed system as possible. The HydroGuard unit combines the time-proven internal check-valves with an expansion chamber to maintain system isolation.
Use the HydroGuard Breather for steady-state installations with minimal fluctuations in temperature to take advantage of protection and reliability this unit affords.

Please Note: The above sizing table is only a general guideline. Many other factors such as humidity level, the frequency of airflow, ambient temperatures and chemical compatibility must be considered to determine the size of a breather accurately. Larger applications, as well as special or unusual circumstances, will in many cases require a thorough analysis. Please contact RO-QUIP for help in determining the proper size a breather.
- Steady-State Operations
- High Humidity
- Low Flow 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.
An essential part of the HydroGuard Breather is the diaphragm that adjusts to air expanion & contraction within the casing. during steady-state operations.
