Bright, reliable lighting can dramatically enhance the enjoyment – and safety – of public and commercial spaces and transitways. People feel safer and more secure when the places they park and walk have bright, working luminaires. But over time, environmental factors can degrade the luminaire’s original level of Ingress Protection (IP). This will allow damaging moisture and contaminants to enter the enclosure.
Better Venting Addresses Lighting Industry Challenges
Lighting enclosures are increasingly vulnerable to the demands of evolving technologies: higher-density components create higher internal temperatures and pressures; transparent lenses make condensation more visible and warranty claims more numerous, and LED bulbs demand longer life of the entire system, requiring more robust protection from both contaminants and condensation.
GORE Protective Vents for outdoor lighting enclosures are proven to reduce condensation and contaminants by:
- providing rapid pressure equalization and release, to extend seal life
- minimizing condensation through more effective vapor diffusion
- preventing entry of contaminants like dust, dirt and debris
- high-performance venting eliminates the need for extra-hardened components, saving weight and costs
GORE® Protective Vents can help your enclosure meet IP and NEMA protection standards.
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:
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.
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:
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.

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.
