Enable trouble-free service and longer product life
Equipment used in the telecommunications industry is subjected
to rapid temperature fluctuations, a variety of particulates, and
exposure to wind, precipitation and solar radiation.
For example, in tower-mounted antennas and other equipment
with active electronics, the internal temperature of the housings
can increase significantly on sunny days. This increases the
pressure inside the weatherproof enclosure, resulting in stress
on the housing seals. Depending on the size of the enclosure, a
sudden rainstorm or high wind can cause a drop in temperature
creating a 200 mbar (3 psi) vacuum inside an enclosure, which
puts stress on the housing’s seals. If the internal pressure is not
equalized, water, moisture, dust and dirt may be drawn into the
housing. This could compromise the equipment performance,
leading to additional maintenance or warranty costs.
Venting for Protection
Installing a vent in equipment housing helps equalize the internal
pressure and minimizes the risk of contaminants entering the
enclosure. GORE Protective Vents are the ideal solution,
because they provide consistent pressure equalization within an
enclosure and help preserve the integrity of the housing’s seals.
®
GORE Protective Vents contain a unique GORE Membrane made
of proprietary expanded polytetrafluoroethylene (ePTFE) that
allows air and gases to flow freely, equalizing pressure. At the
same time, this membrane provides a barrier that helps protect the
electronic components from water, dust and other contaminants
without interfering with the transmission of signals. The result —
increased reliability while helping to provide longer product life
and trouble-free service.

Realize the Benefits of
GORE Protective Vents:
®
•Longer, trouble-free service life, even in extreme
conditions, because of rapid equalization of pressure
and protection from dirt and dust particles
•Protection against water, salts and other corrosive
liquids through reliable oleophobic and hydrophobic
ePTFE properties
•Reduced condensation due to vapor-permeable
venting membrane
•Reduced stress on enclosure seals through rapid
equalization of pressure
•Easy integration for design and manufacturing with multiple
vent options including rugged designs
•Simplified maintenance enabling easy access to the
equipment in the electronic enclosure
•Superior global technical support and broad application
knowledge from Gore’s engineering experts, with over
200 million installations worldwide
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:
®
•tolerate temperatures ranging from –40°C to 125°C
•perform to protection standards up to IP69K*
•provide maximum protection for applications in harsh
environments through molded plastic or metal 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.
