Overview

When a device experiences temperature or altitude changes, a pressure differential between the external environment and the interior of the device can occur. This pressure differential can weaken the gaskets and seals within the device and eventually leads to lower resistance to liquid penetration.

The latest smart phones and many other consumer electronic devices are now made with a flexible, touch-sensitive screen that deflects inward. Consumer handling of these electronic devices can cause rapid pressure changes and pressure differentials between the inside and outside of the device, leading to transducer bias and compromised acoustic performance. GORE® Pressure Vents are engineered to provide optimum airflow within the available design envelope without compromising the required level of ingress protection.

Applications

GORE® Pressure Vents help to equalize pressure fast, minimizing the pressure differentials that can weaken the gaskets and seals within a device, create transducer bias and compromise acoustic performance.

Our range of pressure venting solutions are designed to significantly increase airflow and protect portable electronic devices against rapid pressure changes without compromising on liquid and particulate protection.

Design Considerations

Predicting the conditions your product will encounter can be difficult, so our application engineers will work with you to ensure the right vent is selected.

Factors that might be considered include:

  • What are the required product dimensions (device air volume)?
  • How will the product be used?
  • What are the air flow requirements of your device?
  • What is the target pressure equalization time?
  • What are the minimum and maximum temperatures your device may face?
  • What surface will the vent be mounted on and what type of adhesive is required?
  • How much space is available within your device enclosure? Will there be an open cavity?
