More Reliable Connectivity with Reduced Manufacturing and Maintenance Costs
GORE® Protective Vents for Telecommunication Systems - Applicatioin

Today’s telecommunication systems aim for reliable connectivity everywhere – requiring more equipment in remote locations, and greater exposure to extreme environmental conditions.

GORE Protective Vents can extend the service life of telecommunication equipment, reducing maintenance costs, warranty claims and customer frustrations, because they:

  • effectively manage pressure differentials within the equipment housing
  • prevent condensation from compromising sensitive electronics
  • reduce stress on housing seals
  • block ingress of rain, moisture, wind-borne particulates and other contaminants
  • eliminate the need for “ruggedized” housings, reducing costs and weight

Gore, the global leader in venting technology, has more than 15 years’ experience in developing custom venting solutions for the telecommunications industry. Our global R&D and engineering teams can partner with you from initial product concept through prototyping, sampling, testing and production integration.

GORE® Protective Vents can help your enclosure meet IP and NEMA protection standards.

Why Vent?

Electronic enclosures that are installed outdoors are vulnerable to a wide range of environmental hazards that can affect the performance, reliability and life expectancy of the sensitive electronics within.

Problems for Outdoor Electronics:
Enclosure seal

Pressure differentials are created when a sealed enclosure is exposed to rapid, extreme or recurring changes in ambient conditions. Extreme changes in temperature (a sudden thunderstorm on a hot, sunny day), altitude changes (in transit), or the constant heating and cooling cycle of an internal heat source – any of these can cause a pressure differential within a sealed enclosure. A rapid decrease in temperature, for example, can create a vacuum inside the enclosure. If this pressure differential is not dissipated, the vacuum places continual stress on the housing seals. Over time, this can cause seals to fail, allowing moisture and other contaminants such as dust, dirt and other particulates to be drawn inside.

Cloudy pane due to condensation

In addition to failed seals, moisture can get inside enclosures by diffusion – the process by which vapor moves by natural molecular motion through the walls of a polymer enclosure. When water vapor enters a sealed enclosure and has no way to escape, it will condense to a liquid state. If this condensation remains inside the sealed enclosure, it can compromise lens function and corrode sensitive electronics and battery contacts.

Reliable Solutions with GORE Protective Vents:

Equalize Pressures to Protect Housing Enclosures and Seals

Prevent Contamination to Protect Electronics

Reduce Condensation to Protect Against Corrosion

During normal operation and recharging cycles, batteries can generate heat and emit hydrogen or other gases. This can create a hazardous, or even explosive, situation. GORE Protective Vents effectively dissipate hazardous gas molecules. By continuously equalizing pressures inside and outside the battery compartment, they reduce explosion hazards, while maintaining an effective barrier to liquids and particulates.

Applications

Venting Solutions for Different Telecommunication Applications

View our interactive Telecom Overview brochure to see how GORE Protective Vents can improve the reliability of your telecommunication systems.

Tower-Top Electronic Enclosures
Tower-Top Electronic Enclosures Water can cause corrosion and shorts to the electronics in tower-top enclosures. By allowing moisture vapor to diffuse easily, GORE Protective Vents reduce potential condensation that leads to corrosion and shorts.
Base Station Battery Units
Base Station Battery Units To prevent potential explosions, hydrogen gases from batteries must have an exit path. The continuous airflow of GORE Protective Vents enables gases to flow out of the unit while creating a barrier against contaminants.
Small Cell Nodes
Small Cell Nodes Plastic housings commonly used in small cell nodes are more susceptible to pressure equalization issues. Gore’s venting solutions protect the electronics from water damage and comply with environmental standards.
Antenna Tilt Motors
Antenna Tilt Motors Mechanical components of the antenna motors can fail when exposed to liquids and other contaminants. GORE Protective Vents provide a barrier against liquid and other contaminants that can lead to corrosion.
Coverage Systems
Coverage Systems Water ingress can compromise the signal integrity of coverage devices like repeaters and backhaul devices, including point-to-point and microwave radios. By equalizing pressure inside the device housing, GORE Protective Vents prevent stress on the housing seals so water cannot enter.
Tower-Mounted Sensors
Tower-Mounted Sensors Rapid temperature changes create a vacuum inside the sensor, which can cause a seal to fail. Moisture vapor can enter and condense on the sensor dome, obstructing sunlight and compromising sensor measurements. GORE Protective Vents equalize pressure and prevent vacuums that compromise seal integrity.

PolyVent Stainless Steel Brings Premium Performance and Durability to GORE® Protective Vents Screw-In Series

Posted July 13, 2020

PolyVent Stainless Steel brings premium performance and durability to GORE® Protective Vents Screw-In Series. Its premium-quality materials and construction durably withstand the worst hazards: from aggressive industrial chemicals and cleaners to corrosion-inducing salty offshore environments. For added safety, a flammability-resistant GORE™ membrane (UL 94 VTM-0) and O-ring (UL 94 V-0) complement the non-flammable stainless steel body.

New GORE® PolyVent XS is 30% smaller, for more design options and easier integration into small, thin-walled outdoor electronics

Posted September 30, 2018

GORE® Protective Vents introduces PolyVent XS, for designers who want to achieve more sophisticated aesthetics in todays smaller, lighter-weight and thinner-walled enclosures. About 30% smaller in every dimension than Gore’s Standard and High-Airflow snap-in vents, PolyVent XS has a smaller diameter and a shorter “head” for less external protrusion – so it’s virtually undetectable when installed. Its shorter “legs” mean less protrusion inside the enclosure, for more room and more design flexibility.
