Pressure equalisation elements

Meaning & Function

Fluctuations in temperature triggered by external influences (such as changing weather conditions) can lead to condensation developing within the enclosure. To prevent this from happening, we recommend using pressure equalisation elements.

Our pressure equalisation elements prevent the pressure difference between the inside of the enclosure and the environment, which is responsible for the condensation in the enclosure. The elements made of robust polyamide or stainless steel are fitted with a special air permeable but water repellent membrane in order to maintain the enclosure’s IP protection. You will find solutions in different sizes, materials or colours in our extensive product range.


How many pressure equalisation elements do you need for your application?

The question can be answered quite simply – using our pressure equalisation calculator. Take a look here.
