Venting

Vents for Telecommunications Equipment

Telecome Applications

The problem: 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 a tower-mounted antennas and other equipment with active electronics, heat is dissipated into the housing. This increases the pressure, resulting in stress on the housing seals. 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 are drawn into the housing. This can compromise the equipment performance, leading to additional maintenance or warranty costs.

The solution: Equalize pressure by continuous venting.

GORE™ Protective Vents effectively protect against the negative effects of pressure differentials caused by temperature changes. With their integrated GORE™ Membrane, these vents allow an enclosure to equalize pressure immediately when subjected to changes in temperature and pressure.
