Venting of Housings

Schreiner Group develops application-specific labels which seal enclosures reliably and impermeably to moisture, but allow air exchange.

Venting Elements

Air-permeable membranes, which are gas-permeable and at the same time water-tight, are used for the venting of housings and other components.

Schreiner Group offers a portfolio of membrane materials, so that for almost every application there is a material with the right combination of water-tightness and airflow. A wide variety of formats are possible, which are individually adapted to the design and size of the component. Bonding and welding serve as joining technologies. Aeration elements are easy and cost-effective to apply thanks to label technology and can be combined with various additional benefits.

A label for venting can be used to compensate for pressure differences inside and outside enclosures.

Pollutant Free Products

All Schreiner Group membranes for ventilation and air extraction are free of harmful substances and do not contain perfluorooctanoic acid (PFOA) and PFOA precursor compounds. This ensures that no persistent organic pollutants (POPs) harm humans or the environment and that the EU POPs Regulation is complied with.
