Providing Quality Oil Care to Industry
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.
A domed cap allows for better washdown runoff
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
External ribs on shell to create greater durability and grip when installing or replacing breather
An integrated drip ring keeps shedding water from entering the vent holes
Easily replaces standard filler/breather cap with multi-fit connection or one of several adapters
High-capacity check valves allow for increased airflow at low cracking pressure
Polyester filter element removes airborne contamination to 3-micron absolute. Unique loops allow particles to release during system exhalation, helping to increase breather life
An enhanced seal eliminates potential for airflow bypass

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.
