Des-Case VentGuard™ breathers have check-valve technology that isolates the system and only ‘breathes’ when necessary, making them an ideal solution that protect low-flow applications with intermittent operations. Check valves provide slight system pressurization that allows for controlled breathing without excessive pressure build-up. The system breathes only when pressured to do so, and then the air is cleaned and dried before it is introduced into the system, ensuring a clean, dry headspace. This control mechanism also prevents premature saturation of the silica gel and extends breather life, a problem not as easily tackled by standard desiccant breathers exposed to extreme moisture.

Customized desiccant breathers offer several alternative or secondary agent media options that can be mixed to meet specific environmental and chemical needs.
CUSTOMIZED DESICCANT OPTIONS INCLUDE:
|ORANGE SILICA GEL - Silica gel is the most efficient and economic moisture adsorbent for general applications. Des-Case offers two types of indicating silica gel, blue-to-pink or orange-to-white. The difference between the two is the chemical used to indicate the color-change. Blue-to-pink uses cobalt chloride and orange-to-white uses ferric ammonium sulfate.|
|ACTIVATED CARBON - Activated carbon is an ideal adsorbent in applications requiring fume mitigation or air purification.||
|MOLECULAR SIEVE - Molecular sieve has high efficiency at low levels of humidity. It is best for drying highly polar alcohols, unsaturated hydrocarbons, and static dehydration of gas.|
|ACTIVATED ALUMINA - Activated alumina is most effective in removing organic acids, especially those that are larger in size.||
|LAYERED (BLUE SILICA GEL & MOLECULAR SIEVE) - Mixing media such as silica gel and molecular sieve are ideal for customers needing to adsorb both moisture and fumes simultaneously.|

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.
- Intermittent Operations
- Low-Flow Applications
Check-valves on the bottom of the unit isolate the system until equipment needs to breathe. As air is drawn into equipment through the breather, the layered filter elements remove particulate while the desiccant beads strip harmful moisture. While in service or during shutdown, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.
A pink breather means it has done its job keeping moisture out of your lubricants. Time to replace the breather with a new one.
