VENTING MEMBRANES
For markets such as automotive electronics, sensors or electrical/electronic components in general, housing ventilation is a major issue.
The functioning of electrical or electronic components generates heat and an increase in pressure inside the housing. This overpressure and heat must be evacuated efficiently, to avoid serious damage to the components themselves or to the housing gaskets.
Gergovent ventilation membranes
Each year, GERGONNE manufactures several million ePTFE venting membranes and groups its standard solutions within the GERGOVENT range.
By carrying out tests in our laboratory, we know how to select the venting membranes most suitable for the market’s needs and control their performance (air flow rate, MVTR, water intrusion pressure, climatic and thermal cycle, etc.).
The venting membranes proposed by GERGONNE have been designed to address a variety of issues:
- Safely prevent the intrusion of water, dust and contaminants into the enclosures
- Rapidly balancing overpressure and removing heat
- Efficiently removing moisture to prevent condensation
GERGOVENT ePTFE venting membranes, certified PFOS-free (perfluorooctane sulfonate), improve the lifespan of electronic components and increase their reliability.



Our ePTFE venting membranes can be used for a wide range of applications: automotive lighting (headlights and taillights), electronic circuit boards, sensors, cameras, small electric motors (e.g. window regulators), etc.
Our black VM13 membranes (VM13-RD01, VM13-RD02, or VM13-RD03) have the following technical features:
Air flow at 70 mbars: > 250 ml/min/cm²
Water intrusion pressure (30s): ≥ 1 bar
Operating temperature: -40°C to 150°C
Available in various sizes.

GERGONNE has developed a new venting membrane (VM16). Its design makes it even more resistant to difficult conditions.
Thanks to the Side Protect technology (patent pending), our ePTFE VM16 ventilation membranes provide excellent adhesion and are even more resistant to water pressure.
The black VM16 membrane (VM16-RC01) has the following technical specifications:
Air flow at 70 mbars: > 250 ml/min/cm²
Water intrusion pressure (30s): ≥ 1 bar
Operating temperature: -40°C to 150°C
| Product | Standard shape | External dimension (mm) | Internal dimension (mm) | Air flow at 70 mbars (per part) | |
|---|---|---|---|---|---|
| VM16-RC01 | Rectangle | 40 x 19.5 | 30 x 9.5 | > 712 ml/min | Technical sheet |
