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.
Breather Valves, also known as Pressure Relief Valves, prevent excessive pressure or vacuum buildup in sealed containers, which reduces container weight and cost
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.
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.
