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.
The diaphragm allows for expansion/contraction of the air within the casing as a result of temperature variations during steady-state operations.
Foam filter captures any oil mist and disperses incoming air evenly over filtration and drying area.
The integrated standpipe provides excellent vibration resistance and dissipates impact throughout the unit, eliminating weak points. It also allows even airflow distribution throughout the unit, eliminating inaccurate readings of desiccant saturation.
Silica gel adsorbs water from incoming air and can hold up to 40% of its weight. Condition is indicated by change of colour from blue to light pink.
High-quality umbrella check-valves that won’t clog or stick are recessed underneath the unit for added protection from washdown environments. Check-valves isolate equipment from ambient conditions, prolonging breather life.
Polyester filter element removes airborne contamination to 3-micron absolute. Unique loops allow particles to release during system exhalation, helping to increase breather life.
Shock-absorbing, clear casing provides reliable service and easy maintenance.
Easily replaces standard filler/breather cap with multi-fit connection or one of several adapters.
As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate while the colour-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.

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.
