Pressure Compensation Seals

Pressure Compensation Seals consist of a waterproof and dust-proof but air-permeable membrane. This allows air exchange in enclosures and protects the electronics from moisture and dirt.

 

Pressure Compensation Seals for Venting

Temperature fluctuations occur frequently in the technical industry. Overpressure or underpressure caused by these can deform housings and lead to leakage. Pressure Compensation Seals provide pressure compensation and protect the housing and components. They are gas-permeable and water-tight at the same time.

The business unit Schreiner ProTech has been working with this proven technology for venting of housings since 1997. The membranes prevent pressure differences from occurring in a housing and thus increase the service life of electronic components.
