Breather valves are rated for two different pressures: Cracking pressure and full-flow pressure. The difference between these two measurements is another significant source of misunderstanding on part of many design engineers.
Prevent excessive pressure or vacuum buildup in a sealed container. Reduce the weight and cost of your containers with a Breather Valve (also known as a Pressure Relief Valve).
After moisture or water vapor enters a sealed enclosure, it diffuses through the air inside, where it can later condense during temperature changes. Condensation is a common obstacle in designing sealed enclosures intended to house electronics or other moisture sensitive equipment. To make things worse, moisture will enter a sealed enclosure in four different ways.
Breather valves and immersion breathers both relieve pressure but operate differently and have different implications for moisture control. We'll look at the differences here and provide best practices for installation.
