Both, automotive and electronic applications, require more and more securely sealed housings for electronic devices. Water sealed boxes are not in every case the best solution due to formation of condensation water at different temperatures. Also steam can easily migrate through the thin walls of these kind of housings.

Subsequently the break down of the electronic systems are possible. Therefore the integration of pressure compensation units with membranes is increasing in these kind of applications. Hydrophobic RoTrac® Membranes with its ideal combination of high airflow and secure water resistance are the right choice and a reliable solution.
