With very high volumes production GVS is the world leader in the production of injection-molded ventilation valves for electronics packaging and waterproof ventilation filters.

Retaining water and simultaneously allowing air to pass freely through the filter media, vent filters enable the continuous exchange of gasses and vapors.

This provides pressure equalization within the auto parts enclosures that are often exposed to fast temperature fluctuations, causing extreme changes in internal pressure, and reducing condensation, protecting electrical parts from pollution and liquid.
