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.
Sizing & 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 Ecochem Pumps for assistance in sizing a breather.

How it works
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.
– Removes moisture in the headspace of equipment
– Eliminates rust-forming condensation
– Prevents sludge deposits and water-contaminated oil
– Prevents contamination ingress
– Provides longer lubricant life
– Reduces wear and tear on equipment, prolongs life
