AUTOMOTIVE VENTING

______________
Protect your automotive electronics from outside water and dirt with a broad spectrum of automotive-specific membranes
Slider

In the challenging automotive environment, protection against outside water and dirt is key, while a stable pressure compensation or active venting function is needed to avoid damage or even failure of electronic components over the vehicle’s lifetime. Oxyphen’s products are used widely to protect all kinds of sensors and actuators with various housing types in all vehicles.

Oxyphen has the technology and products to solve your automotive venting needs with high quality to protect your electronics parts over their lifetime. With our experience for automotive and electronic applications, we have the expertise to choose the best membrane solution from our existing and approved portfolio or develop a customized solution for your individual requirements.

Electronic and sensor housing protection

Small electronic housings – especially sensor housings – need maximum protection against water and dust/dirt; however the gas flow should be minimal to avoid the transport of water molecules.

Sensors fulfill a very sensitive function within the automotive infrastructure, which require membranes to secure their housing with highly defined and stable characteristics.

The Oxyphen membrane technology enables a very uniform gas flow while simultaneously mazimizing protection against outer media.

Headlight venting

Headlamp venting

Venting applications are increasingly more important in the automotive segment. Headlamp assembly systems require a specific airflow in order to cool the system and to prevent condensation of moisture; however, liquids and dirt particles are not allowed to enter the lamp assembly. This challenge can be easily solved with our hydrophobic fiber-based membranes.

Key benefits

  • 100% Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
  • Remove moisture through maximum airflow
  • Vent the headlamp to cool down the modules
  • Prevent the entry of splash water and dust

Technical specifications

Available Options:

  • Airflow : Up to 3,000 l / (bar cm2 min)
  • Water entry pressure (WEP): Splash water protection up to 30 mbar
  • Design: Rectangular or disc currently up to 55 mm
  • Applicable temperature range: -40 to + 150 °C (up to 180° C for special applications)

Materials offered:

  • PET bonded fiber membranes
  • PP bonded fiber membranes

Battery Venting

Battery Venting

Venting and protection solutions for battery technology/battery packs are critical in the current automotive landscape. The technical challenge for these applications can best be solved with our hydrophobic membranes. Pressure balancing in combination with water tightness is a requirement for large and small scale battery pack systems. In addition, safety features such as blow-by function in case of cell defect can be incorporated into a venting system.

Key benefits

  • 100% Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
  • Macro venting for fast pressure balancing of large capsules
  • Micro venting for high protection against water and dust
  • Adjustable emergency venting function to fulfill a defined burst pressure requirements

Technical specifications

Available options:

  • Airflow: Up to 1’700 l / (bar cm2 min)
  • Water entry pressure (WEP): Splash water protection up to 3 bar
  • Standard dimension: Outer diameter up to 55 mm
  • Adjustable burst pressure for emergency venting: From 0.2 – 5.0 bar​
  • Applicable temperature range: -40 to + 150 °C (up to 180 °C for special application)

Materials offered:

  • PET Track-Etched unlaminated
  • PET Track-Etched laminated with PET/ PP non-woven
  • PET fiber bonded membranes

Small lamps and side indicator lamps

Avoid fogging and cracks on the housing of small lamps like side indicators or fog lamps that are directly exposed to the harsh outer weather conditions due to their mounting spots directly on the vehicle’s exterior.

Key benefits

  • 100% Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
  • High protection against water and dust
  • Strong defogging characteristics

Technical specifications

Available options:

  • Airflow: Up to 37 l / (bar cm2 min)
  • Water entry pressure (WEP): Splash water protection up to 3 bar
  • Standard dimension: Outer diameter up to 14 mm
  • Applicable temperature range: -40 to +150 °C (up to 180 °C for special applications)

Materials offered:

  • PET track-etched unlaminated
