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.

With appropriate design conditions (please consult Gore associates).
PE12 and PE13 can meet IP68 (1.5 m water for 30 minutes).
Normally, PE16 and PE8 can meet IP67. For certain designs, IP68 (1.5 m water for 30 minutes) can be met.
PE7 can meet IP68 (2 m water for 1 hour).

2 In compliance with ISO22810:2010(E) test method 4.3.2 Water resistance to overpressure.

Pressure Vents provide superb reliability through exceptional balance of airflow and water 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?

Available in custom and standard sizes to give manufacturers greater design flexibility — to either reduce the number of pressure vents used in their devices or reduce the size of pressure vents for devices with limited internal space — without reducing effectiveness.

Gore applications engineers are also available to assist in selecting the right solution for your specific application requirements.
