Overview
Venting to Improve Performance, Value and Profit

Solar energy systems are challenged by the changing demands of evolving technologies, by harsh operating conditions that can threaten performance, and by customer demands for decades-long service life.
Advanced venting solutions from Gore can help reduce engineering complexity and fabrication costs while maintaining higher system efficiency over the long lifespan customers expect.
GORE Protective Vents for solar system housings are engineered to deliver higher performance over the long term, helping solar systems to do the same. Gore vents:
- provide rapid pressure equalization to ensure the seals maintain the original level of Ingress Protection (IP) rating over the life of the product;
- block ingress of liquids and contaminants like salts, sand, or dust;
- diffuse water vapor more effectively, minimizing condensation damage and improving system power output;
- are available in screw-in, snap-fit or welded membrane styles for easy integration into any housing design;
- are tested and proven to meet the world’s most demanding enclosure-protection standards including Underwriters Laboratory (UL), Technischer Überwachungsverein (TÜV) and International Electrotechnical Commission (IEC).
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:
Reliable Solutions with GORE Protective Vents:
Applications
Venting Solutions for a Variety of Solar Applications
Junction Box | |
![]() |
Water can cause corrosion and shorts to the electronics in junction boxes. By equalizing pressure inside the box, GORE Protective Vents prevent stress on the housing seals, so water cannot enter. |
CPV Modules | |
![]() |
The large dimensions of the CPV modules make them susceptible to pressure differentials caused by temperature changes. Installing GORE Protective Vents in the housing equalizes pressure and increases efficiency. |
String Combiner Box | |
![]() |
Regardless of the size and volume of the string combiner box, Gore can customize a venting solution to ensure the reliability of the seals and gaskets, protecting the connectors from shorts caused by water. |
Tracking Equipment | |
![]() |
Exposure to water and other contaminants can compromise the mechanical components of the tracking system. GORE Protective Vents provide a barrier against liquid and other contaminants that can lead to corrosion. |
Micro / String Inverter | |
![]() |
Corrosion can quickly damage the sensitive electronics inside the micro/string inverter. GORE Protective Vents prevent degradation by providing a durable barrier against water, oils and other liquids. |
Monitoring Equipment | |
![]() |
Condensation can compromise the performance of control components. By allowing moisture vapor to diffuse easily, GORE Protective Vents reduce the potential for condensation inside the enclosures. |

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.
MUNICH, GERMANY (November 29, 2017) – W. L. Gore & Associates proudly announces the launch of GORE® PolyVent Ex+. Our latest addition to the Protective Vents Screw-In Series is certified according to explosion-proof safety standards, IECEx and ATEX. This will allow you to sell your products globally with fewer certification efforts, saving you labour and testing costs. Plus, the PolyVent Ex+ offers you additional protection performance due to its unique design.
The newly launched GORE® PolyVent Ex+ adds explosion protection according to IECEx and ATEX to GORE® Protective Vents Screw-In Series. GORE® PolyVent Ex+ offers additional plus (+) features that truly deliver the uncompromising and reliable product performance which is required in tough environments and add to the “long-time safety aspect” for both – operators and equipment.
