Des-Case Ventguard Breathers

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.

Did you know?

  • Particle contamination is responsible for as much as 80% of machine wear?
  • It costs ten times as much to remove contamination from equipment than it does to exclude it.
  • Moisture contamination is the second most destructive contaminant in most systems?



This breather unit replaces the standard dust cap or OEM breather cap on equipment. Check- valves on the bottom of the unit isolate the system until equipment needs to breather. 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.


Key features of the Des-Case VentGuard Breather include:


1. Domed Cap
A domed cap allows for better washdown runoff.

2. Integrated Nylon Standpipe
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.

3. External Ribs
External ribs on shell to create greater durability and grip when installing or replacing breather.

4. Integreated Drip Ring
An integrated drip ring keeps shedding water from entering the vent holes.

5. Threaded Mounting
Easily replaces standard filler/breather cap with multi-fit connection or one of several adapters.

6. Larger, High-Capacity Check Valves
High-capacity check valves allow for increased airflow at low cracking pressure.

7. Filter Element
Polyester filter element removes airborne contamination to 3-micron absolute. Unique loops allow particles to release during system exhalation, helping to increase breather life.

8. Enhanced Seal
An enhanced seal eliminates potential for airflow bypass.


The Des-Case VentGuard range includes the Des-Case DC-VG-BB, Des-Case DC-VG-1, Des-Case DC-VG-2, Des-Case DC-VG-3 and the Des-Case DC-VG-4.
