GORE® Acoustic Vents for Industrial Applications

Reliable Acoustic Protection for MEMS Microphones & Speakers

GORE^® Acoustic Vents are engineered to protect sensitive electronics while preserving sound quality. They equalize pressure, manage condensation, and simplify housing design—reducing weight, complexity, and cost. At the same time, they block moisture and contaminants to extend device life and ensure reliable acoustic performance - even in the harshest conditions.

How It Works

Enhance Service Life and Acoustic Integrity

GORE Acoustic Vents for Industrial Applications offer a simple, effective way to protect devices from environmental exposure while maintaining the acoustic performance of traditional and MEMS microphones, speakers, and receivers.

Rapidly equalize pressure to increase service life, effectively manage condensation and reduce housing design complexity, weight and costs.
Reliably protect sensitive electronics from moisture-related damage.
Effectively block ingress of contaminants: water, other liquids, dirt, dust or salt which can build up over time.

Protect from Acoustic Degradation from Environmental Contaminants

Each of our vents features an innovative membrane, engineered to reliably protect against a specific level of contaminant ingress while enhancing acoustic performance and transparency. Our portfolio offers solutions for:

Microphone dust-and-splash protection
Fully watertight and dust-tight microphone protection for industrial settings
Dust-and-splash and watertight protection for outdoor speakers in harsh environments

Our vents enhance acoustic performance while reliably protecting against damaging contaminants.

Protect Your Sensitive Electronics

Typical industrial applications include:

Security cameras
Two-way radios (industrial use)
Outdoor intercom
Human/machine interface devices
Smart farming

Traffic monitoring
Washing machines
Interactive information displays
Robotic devices
Power grid devices

Our portfolio includes two series of protective vents, each engineered to address a different set of performance requirements.

Series 400: Superior Fluids and Dust Protection, Outstanding Acoustics

Series 400 (412 and 434) eliminates the typical trade-offs between reliable waterproofing and superior sound quality. It combines our most advanced ingress protection with outstanding acoustic performance.

Reliably waterproof: Delivers IPx8 protection (no water intrusion after immersion at 2 meters for 30 minutes).
Durably oleophobic: Effectively repels oils, common industrial fluids and cleaning solutions that can threaten ordinary vent materials.
Effectively dust-proof: Qualified IP6x dust-proof, and when tested in assembled devices, protects against airborne/smog-borne particulates as small as 1–10 μm in size.

Series 200: Splash and Dust Protection without Compromising Sound

Series 200 (212 and 234) effectively protects industrial devices from environmental splash and dust hazards while providing enhanced broadband acoustic transparency.

Outstanding Acoustics: Three-dimensional non-woven membrane maintains sound-wave integrity and protects against acoustic degradation, for excellent sound performance.
Reliable splash resistance: Our oleophobic membrane provides a higher level of spray protection than ordinary woven mesh vents at a given level of acoustic performance.
Efficient particle capture: Our three-dimensional membrane structure traps small particles of varied sizes and shapes much more efficiently than ordinary woven mesh vents, to enable better device reliability.

How It Works

Our membranes are made of expanded polytetrafluoroethylene (ePTFE). Gore invented this highly versatile polymer, and we can tailor our membranes’ structure and performance characteristics to meet a wide range of application needs.

The membrane repels liquids and particles while allowing pressure equalization and enabling clear sound transmission, so microphones, speakers and receivers in industrial applications can continue to perform reliably.

Whether your application requires exceptional barrier protection, or exceptional sound transmission, or a specific balance of both, the membrane makes it possible.

Liquid and particles are repelled. The membrane ensures pressure equalization while allowing sound transmission.

For Microphones in Industrial Applications

The same apertures that enable microphone sound transmission also can make it easy for liquids and particles to enter and degrade both acoustic quality and device reliability. Gore offers a range of industrial acoustic vents designed to protect against these threats:

For Speakers & Receivers in Industrial Applications

With their larger apertures, speakers and receivers can be more vulnerable to ingress of fluids and contaminants. The device’s magnets may also attract metal particles that can accumulate and degrade sound quality. Gore offers a range of industrial acoustic vents designed to protect against these threats:
