Overview

Increase Equipment Life Expectancy and Performance Reliability
GORE® Protective Vents for Heavy Duty Equipment - Applications

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

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:

Failed Seals

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.

Condensation

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

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.

Equalize Pressures to Protect Housing Enclosures and Seals

Prevent Contamination to Protect Electronics

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.

Air passes through the membrane. Liquids and particles are repelled.

Reduce Condensation to Protect Against Corrosion

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.

Water vapor molecules pass through the membrane

Protect Against Hazardous Gas Buildup

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.

Gas molecules pass through the membrane
