Increase Equipment Life Expectancy and Performance Reliability
When customers invest in heavy-duty equipment, they expect exceptional durability and reliable performance. Yet the harsh operating environments can threaten the performance and life expectancy of sensitive electronics, causing reliability problems and expensive warranty claims.
GORE Protective Vents provide the optimal combination of breathability and barrier protection to enhance the survival of electronic components in the most demanding applications. In heavy-duty construction, agricultural or material handling equipment, GORE® Vents reliably protect against dirt, dust, condensation, humidity and water.
Vents from Gore can extend the service life of electronics in heavy-duty equipment, reducing maintenance costs, warranty claims and customer frustrations, because they:
- rapidly equalize housing pressures, to avert premature seal failure
- prevent ingress of moisture, wind-driven rain and particulates and other contaminants
- reduce condensation that can corrode sensitive electronics
- eliminate the need for “ruggedized” housings, reducing costs and weight
- provide a compact, venting structure that is easily installed and integrated
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:
GORE Protective Vents rapidly equalize pressure differentials within sealed enclosures, effectively preventing the internal vacuums or pressure build-ups that stress housing seals. In non-vented housings, pressure differentials as low as 70 mbar (1 psi) can cause seals to leak after repeated temperature cycles. GORE Vents reliably protect against premature seal failure, to preserve the integrity of the enclosure.
GORE Protective Vents reliably block ingress of a wide range of contaminants, from rain and insects to dirt, dust, sand and other particulates. Yet GORE Vents allow air molecules to pass through, preventing the formation of vacuums that could pull external contaminants in. With vents from Gore, components perform reliably, with lower maintenance or warranty costs.
GORE Protective Vents enable water vapor molecules to diffuse through the microporous membrane, and pass freely out of the enclosure. By reducing the amount of internal moisture, internal surfaces such as lenses are protected from condensation, and electronics are protected from premature failure due to 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.
Venting Solutions for a Variety of Heavy-Duty Equipment and Applications
|GORE Vents reliably protect electronic systems in earth moving equipment, in road construction equipment, and in equipment for the mining industry.|
|Material Handling Equipment|

|An investment in tractors, harvesting and cultivating equipment, or forestry equipment is protected for longer when GORE Vents extend the life expectancy of outdoor electronics.|
Today's construction, agricultural and material handling equipment relies on sophisticated electronics to get the job done. And wherever you find those electronics, you can find GORE Protective Vents. They reliably protect all types of enclosures in all types of heavy-duty equipment applications.
Screw-In vents provide durable protection against water, salts and corrosive liquids, even after immersion. The threaded shaft and durable O-ring provide increased mechanical stability, and these hydrolytically-stable vents are UV- and temperature-resistant, for added durability and longer product life. Designed for easy installation in any application, these rugged vents come in five different styles:
|GORE® PolyVent XS
has a compact, low-profile design that meets some of the industry’s toughest standards, making it ideal for today’s smaller (up to 2 l) housings.
|GORE® PolyVent Standard (M12x1 and M12x1.5)
offers reliable venting for volumes up to 5 l, and comes in two colors and two thread sizes for different wall thicknesses, with or without a counter nut.
|GORE® PolyVent High Airflow (M12x1.5)
has the protection level of “Standard” – with nearly ten times the airflow. For housings up to 50 liters, it easily manages the strong pressure differentials caused by extreme weather.
|GORE® PolyVent XL
maintains exceptionally high airflow in extra-large enclosures (volumes up to 200 l) and meets the most rigorous standards, such as solar resistance (IEC 62108).
|GORE® PolyVent Stainless Steel
offers premium-level durability, corrosion- and chemical resistance, to reliably protect enclosures up to 20 liters in the most extreme conditions.
|NEW GORE PolyVent Ex+
is both IECEx and ATEX certified for equipment operating in potentially explosive environments and offers exceptional venting performance for enclosures up to 20 liters in volume.
Snap-In Vents deliver robust venting performance and consistent, long-lasting protection in very harsh environments. Engineered specifically for high-throughput production applications, these vents can be quickly installed with semi- or fully- automated equipment. Most products in this series are individually laser-marked, for full product traceability. Four performance options are available to accommodate different housing sizes and provide varying speeds of pressure equalization:
|GORE® PolyVent Supra
is the low-profile solution for enclosures with limited space for vent installation, and volumes up to 0.5 liters.
|GORE® PolyVent Hysi
offers fast, economical integration, and the option to inside-mount for nearly-invisible installation. For enclosure volumes up to 2 liters.
|GORE® PolyVent Standard
offers reliable performance in many applications, for enclosure volumes up to 5 liters.
|GORE® PolyVent High Airflow,
in hydrophobic or oleophobic versions, delivers high airflow for enclosure volumes up to 30 liters.
Low-profile adhesive vents provide the flexible integration options for almost any application. They can be installed quickly and easily on the interior or exterior of an enclosure, using manual or automated processes. While these vents can easily be customized for the demands and geometry of a specific application, our standard product portfolio offers a wide variety of sizes, designs and constructions.
