OXYSEAL PRESSURE COMPENSATION UNITS

______________

Plug-in venting solution for housings with inverted cylindrical openings

OxySeal® pressure compensation units with hydrophobic membranes are used for ventilation purposes where water needs to be reliably retained, and a gas exchange or pressure compensation is needed at the same time. OxySeal pressure compensation units are a plug-in solution for housings having inverted cylindrical openings. Each unit consists of a hydrophobic track-etched membrane that has been injection-molded with a thermoplastic elastomer seal, which keeps the unit in the opening without any additional anchor or fastener. OxySeal units are customizable according to the specific requirements of the customer, including the selection of the dimensions, membrane technology, and the form of the pressure compensation elements.
