Frequently Asked Questions for GORE® Portable Electronic Vents


1. What types of applications are appropriate for GORE® Portable Electronic Vents?

The variety of sizes, shapes and membrane constructions of these vents allow them to be used in a myriad of applications, such as mobile phones and cases, tablets, laptops, cameras, GPS devices, handheld scanners, two-way radios and MP3 players.

2. Are there different levels of water protection?

Yes, several standards define the type of protection, intensity and exposure time (along with several other metrics) that determine the rating of a device’s resistance to weather and contaminants.

4. How do GORE® Portable Electronic Vents protect electronics?

The reliable performance of GORE® Portable Electronic Vents is rooted in our unique breathable materials. Our microporous membrane prevents pressure buildup by constantly equalizing the difference in pressure between the inside of the device and its immediate environment. This constant exchange reduces the pressure on device seals. The vent works by allowing air and other gases to pass through the membrane freely while blocking liquids and particulates from entering the device. Our membranes offer varying flow rates and liquid protection.

5. How do GORE® Portable Electronic Vents transmit sound?

Gore offers two types of acoustic vents with materials that transfer sound through the acoustic system differently. The resistive material used in vents for dust and splash applications allows sound waves to pass directly through the material. The reactive membrane used in vents for immersion applications responds to and accurately reproduces the sound waves based on mechanical vibration. The performance requirements of your application determine which type of vent is recommended for your device.

6. How much does waterproofing a device costs?

The cost of protecting a device depends on its unique form and mechanical features. We collaborate with our customers to create optimum, customized solutions to ensure maximum protection without added costs. The cost of purchasing GORE® Portable Electronic Vents includes our engineering, testing, manufacturing, launch and post-launch consulting. We monitor and strive to improve the performance of our solution. Please contact us for more information.

7. Does the membrane equalize pressure in both directions?

GORE® Portable Electronic Vents allow air and vapor to pass freely through the membrane in both directions, which reduces potential condensation inside a device. At the same time, the membrane serves as a barrier that prevents exposure to liquid and other contaminants.

8. What’s the difference between hydrophobic and oleophobic materials?

Hydrophobic materials protect against high-surface tension aqueous liquids, while oleophobic materials protect against water as well as low-surface tension fluids like oils, soaps and alcohols. Gore offers vents with both hydrophobic and oleophobic membranes, depending on your application requirements.

9. How do I know if I need oleophobic material?

The environment in which your product is used determines whether you need hydrophobic or oleophobic material. For example, you may require oleophobic material if your device is exposed to fluids other than water such as soap or alcohol. If you have further questions regarding specific chemicals or fluids, contact your Gore sales associate.

10. How do GORE® Portable Electronic Vents differ from mesh vents?

Mesh vents are made of a woven membrane that has a uniform pore size defined by the width of the open squares between fibers. This pore size allows particles such as human hair or metal fibers to pass through a mesh vent because of their shape. GORE® Portable Electronic Vents are made of non-woven materials with a three-dimensional structure that captures particles of various shapes and sizes. They are also more likely to maintain consistent airflow because they capture particles in a torturous path not limited by a specific pore size.

11. How do I select the right vent?

Several criteria, such as the type of transducers used in your device, temperature range, immersion requirements and the environment in which the device will be used all affect the choice of venting solution. Our application engineers are dedicated to work with you to identify your constraints, test various alternatives, and assist in product design to ensure that your electronics are protected for the life of your product. Please contact us for more information.

12. How many vents do I need?

There are a variety of considerations that determine the type and number of vents you need in a device. For example, in a typical acoustic device with separate microphones, receivers and speakers, the location of each component and the mechanical design will determine how many GORE® Acoustic Vents you will need. In addition, you may also need to equalize pressure inside the sealed device with a GORE® Pressure Vent.

13. What are my options for colors?

Our goal is to maintain a low profile in the device, so we offer our vents in white or dark gray/black to minimize the contrast between the component color and our vent.

14. How do I know if I need an acoustic vent or a pressure vent?

All GORE® Portable Electronic Vents equalize pressure while preventing contaminants from entering the device. In addition, GORE® Acoustic Vents are customized to provide optimal sound quality while protecting the electronics. The materials used in these vents transfer sound through the acoustic system differently. The type of acoustic components and the level of sound performance required in your device determine whether we recommend an acoustic vent or a pressure vent.

15. For acoustic vents, when do I need a vent for immersion protection instead of one for dust and splash protection?

GORE® Acoustic Vents for dust and splash protection meet industry standards to protect against common environmental challenges such as rain, spilled coffee or being dropped in a puddle. GORE® Acoustic Vents for immersion protection meet industry standards to protect against complete, continuous submersion in water. Gore does additional testing beyond industry standards to ensure that our products can withstand real-world challenges.

16. For pressure vents, where should I place the vent hole?

Based on almost 30 years of experience with venting technology, we recommend installing the vent on the top or on a vertical side of the device to maximize airflow.

17. What if Gore’s standard product forms do not meet my needs?

We offer a variety of product forms, and if one of these does not meet your need, our application engineers will work with you to develop a customized solution. Please contact us for more information.

18. How are GORE® Portable Electronic Vents supplied?

Vents are supplied as cut parts in either roll or sheet form. Our global team will work with you to understand your supply chain and deliver GORE® Portable Electronic Vents in a form that meets your production needs and schedule.

19. Are product sheets available for GORE® Portable Electronic Vents?

Our data sheets provide specifications for all of our standard parts. Our engineering team will review your specific application to select the correct material, size, stack-up and such specifications as acoustic performance, airflow, water entry pressure, etc.

20. How can I get more information about Gore® Portable Electronic Vents?

As a global enterprise, we have sales offices located worldwide. To request information, contact your local Gore sales associate, or fill out the form on our Contact Us page.

21. How are these vents installed?

Installing the GORE® Portable Electronic Vent consists of a simple three-step process: prepare the surface, position the vent on the device and apply light pressure to the adhesive ring that seals the vent onto the device. A guide for installation and handling is available from our sales and technical support team.

22. Where are GORE® Portable Electronic Vents engineered, tested and manufactured?
