Venting for Protection
Harsh or changing environmental conditions cause pressure
changes that can stress outdoor enclosure seals to failure,
allowing contaminants to enter and damage sensitive electronics.
GORE
®
Protective Vents effectively equalize pressure and
reduce condensation in sealed enclosures, while keeping out
solid and liquid contaminants. They can improve the safety,
reliability and service life of outdoor electronic devices.
A Venting Portfolio for Any Application
GORE
®
Protective Vents Snap-In Series delivers robust
venting performance and consistent, long-lasting protection,
even in very harsh environments. Engineered for use in high-
throughput (semi- or fully-automated) production lines, they
also allow quick and easy manual installation. All Snap-In
Series vents are manufactured with 100% in-line quality
inspections; most are individually laser-marked for full product
traceability. Four PolyVent performance options meet diverse
application needs:
• GORE
®
PolyVent Supra is the low-profile solution for enclo-
sures 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.
Fast, reliable installation and durable protection
for enclosures of all sizes
Realize the Benefits of
GORE
®
Vents Snap-In Series:
• Fast installation on any production line: automated,
semi-automated or manual.
• Reliable performance: snap-in construction securely
seats and seals the vent to the housing.
• Durable protection: even after immersion, the GORE
TM
Membrane blocks contaminant ingress.
• Rugged durability: engineered for chemical and
temperature resistance, and hydrolytic stability.

Recommended Installation
Units are in mm
• Install on a flat, vertical housing surface where
water or other contaminants will not pool.
• PolyVent Supra, Standard and High Airflow are
designed to be installed from outside the enclosure.
• PolyVent Hysi is designed to be mounted from inside
the enclosure. (It can also be mounted from outside,
but inside-mounting is recommended.)
