W.L. Gore & Associates has released a line of compact air vents that is about 30 percent smaller than the company's PolyVent Snap-Fit product family. According to the firm, the PolyVent Compact Series is easier to integrate into even the smallest housings, and provides a higher level of protection for sensitive components such as sensors, motors and control units, while offering reliable and rapid pressure equalization.

The combination of protection and pressure equalization is due to an enhanced microporous GORE membrane that breathes to allow airflow, yet blocks entry of water and contaminants, the company indicated.

GORE PolyVent Compact Series

The GORE PolyVent Compact Series offers a higher-performance venting in a smaller footprint for automotive electronic housings.

Only 14.3mm in diameter, the smaller vent has a low installed-height of only 3.45mm, making 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. The smaller total vent height (only 8.9mm) provides more flexibility in component layout, and facilitates heat transfer from PCBs to the housing exterior.

The enhanced oleophobic GORE membrane design provides about 30 percent better water entry pressure (WEP) resistance, yet with the same airflow and chemical resistance as the PolyVent Standard and High Temperature Series, added the company.
