HYDROGUARD® BREATHERS
Des-Case HydroGuard® breathers uniquely feature an expansion chamber and internal check valves that create a nearly-sealed system. Designed specifically for steady-state operations with minimal temperature fluctuations, these breathers provide excellent protection in continuous duty applications.

Please Note: This is intended as a general guideline for sizing only; other considerations, such as: humidity level, frequency of air flow, ambient temperatures, and chemical compatibility are very important in sizing a breather properly. Larger applications and special circumstances typically require the most thorough analysis. Please contact Des-Case for assistance in sizing a breather.
APPLICATIONS
- Steady-State Operations
- Gearboxes
- High Humidity
- Washdowns
- Low Flow Applications
As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate while the color-indicating silica gel extracts moisture. The diaphragm allows for expansion/contraction of the air within the casing as a result of temperature variations during steady-state operations. When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere.
Seeing Pink?
A pink breather means it has done its job keeping moisture out of your lubricants. Time to replace the breather with a new one.
