The DIAvent© Lineup – Versatile Pressure Elements for Nearly All Applications

Solutions Range from Combined Pressure Equalization and Emergency Degassing to Operation in an Oily Environment

The transition towards e-mobility brings new challenges to vehicle design in respect to pressure equalization. Hermetically sealed housing of lithium-ion batteries for vehicles must be equipped with special pressure equalization devices, as an example.

The DIAvent product portfolio offers a spectrum of solutions including bidirectional pressure equalization, emergency degassing during a worst-case scenario – the thermal runaway of a cell – to the two-way ventilation of an oily environment. Choose the DIAvent advantage by completing the form below.
