DC-VG-BB Button Breather

DCE-VG-BB, 2.5" x 3.9" VentGuard Button Breather

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.

All Des-Case desiccant breathers that use blue indicating desiccant are CE certified and in compliance with REACH Regulation (EC) No 1907/2006. Since February 1, 2020, Des-Case Corporation's decision unifies the labelling of products on the global market.

The European product designation "DCE-" is replaced by the global prefix "DC-".

We will be happy to send you the SDS for desiccant or instruction sheet on request.
