Reduce condensation and simplify maintenance for longer
product life
Lighting enclosures are exposed to varying climate conditions that
can impact the effectiveness of the product. Water, dirt and dust
can also degrade the performance of the lighting unit and create
aesthetic and safety concerns.
Rapid changes in the external temperature cause dramatic pressure
changes inside the lighting enclosure. For example, during a normal
power cycle a vacuum of 200 mbar (3 psi) or more can occur inside
an enclosure, resulting in extreme stress that creates gaps in the
enclosure seals. If the internal pressure is not equalized, the resulting vacuum will draw in contaminants and moisture, increasing
condensation and eventually causing the lighting unit to fail.
Venting for Protection
GORE Protective Vents provide the best solution for equalizing
pressure in lighting enclosures and eliminating the vacuum that
draws in harmful contaminants and water. The unique characteristics of these vents respond to pressure change by continuously
allowing air to enter and exit the lighting enclosure. These vents
also provide an effective barrier against harsh weather conditions
(e.g., rain, snow, high winds), while allowing water vapor to exit
quickly and reduce the likelihood of condensation on the lens.
®
GORE Protective Vents provide outstanding protection because
GORE Membrane is used in the vent, which is made of proprietary
expanded polytetrafluoroethylene (ePTFE). While the GORE
Membrane allows air and gases to flow freely in and out, its
hydrophobic and oleophobic attributes prevent any contaminants
and liquid from entering the lighting enclosure. The result —
equalized pressure and reduced condensation for longer life and
more reliable lighting.

Diverse Product Line
Engineered for Simple Integration
GORE Protective Vents are manufactured in many different sizes
and shapes, making it easy to choose the right vent for any
application. With a diverse product portfolio, these vents are easy
to integrate into new or existing designs to meet the needs of a
broad range of applications and markets. The versatility of GORE
Protective Vents is apparent in both their range of protection and
their ease of installation. For example, these vents:

FOR INDUSTRIAL USE ONLY. Not for use in food, drug, cosmetic or medical device manufacturing, processing, or packaging
operations. The optimal performance of any GORE® Protective Vent depends on how it is handled and incorporated into the
final product. This includes such elements as the device design, sealing method, and assembly method. While Gore is able
to provide general guidelines based upon our experience with the GORE® Protective Vent, it is ultimately the responsibility of
the device manufacturer to validate each product and its performance for its intended application. Contact a Gore technical
sales associate today for assistance in determining the best GORE® Protective Vent for your specific application.
