December 6, 2013 - GOREŽ PolyVent Compact Series features microporous GORE™ membrane that breathes to allow airflow yet blocks entry of water and contaminants. This provides protection for sensitive components, such as sensors, motors, and control units, as well as pressure equalization. Vent diameter is 14.3 mm, and 3.45 mm installed height minimizes external protrusion and vulnerability to mechanical impacts or steam-jets. Construction features hydrostabilized PBT GF30 vent body and silicone O-ring.

New GoreŽ Polyvent Compact Series Vent Delivers Higher Performance in a Smaller-Footprint for Automotive Electronic Housings

ELKTON, MD -- With its new GOREŽ PolyVent Compact Series, W. L. Gore & Associates, Inc. introduces higher-performance venting in a smaller footprint for automotive electronic housings.  About 30% smaller than the widely-used PolyVent Snap-Fit product family, the new GOREŽ PolyVent Compact Series is easier to integrate into even the smallest housings. It provides a higher level of protection for sensitive components like sensors, motors and control units, while providing reliable and rapid pressure equalization.  The combination of protection and pressure equalization is due to an enhanced microporous GORETM membrane that breathes to allow airflow, yet blocks entry of water and contaminants.

The GOREŽ PolyVent Compact Series' smaller dimensions allow for more design options and smaller, lighter weight housings.  The smaller vent diameter (only 14.3 mm) makes the GOREŽ PolyVent Compact Series easier to integrate into today’s smaller housing designs, especially when the installed housing has very limited clearances. Low installed height (only 3.45 mm) affords less external protrusion and less vulnerability to mechanical impacts or steam-jets. Often, no protective wall is needed, so housing design is simplified, development is less costly, and the enclosure more readily fits into the tightest under-hood spaces. And the smaller total vent height (only 8.9 mm) provides more flexibility in component layout, and facilitates heat transfer from printed circuit boards to the housing exterior.

The new GOREŽ PolyVent Compact Series provides advanced levels of protection to extend the reliability and service life of sensitive electronic components. An enhanced oleophobic GORETM membrane design provides about 30% better WEP (Water Entry Pressure) resistance, yet with the same airflow and chemical resistance as the PolyVent Standard and High Temperature Series. Also, the GOREŽ PolyVent Compact Series uses the same advanced PolyVent materials technology – such as a hydrostabilized PBT GF30 vent body and silicone O-ring construction – that has been proven reliable in automotive applications worldwide.

“The new GOREŽ PolyVent Compact Series was designed as a best-in-class solution for two crucial industry needs,” said Rainer Enggruber, Global Product Manager at Gore. “Its compact size supports automotive engineers who are developing ever smaller and lighter under-hood housings. And its performance surpasses today’s most rigorous industry standards to help OEMs facing the dual demands of longer warranties and even harsher test requirements in the future.”
