Global Field Testing / Theoretical Lifetime Modelling

The environmental conditions in locations chosen for deployment of Telecom outdoor base stations are highly variable. Seashore, industrial areas, mega-cities, arctic regions, forests, deserts and other extreme spots burden the ambient air with particles of different natures and origins: road dust, diesel exhaust, hydrocarbon particles, corrosive salts, pollen, sand and many other kinds of contaminants that cannot be clearly defined. Even highly sophisticated computer simulation or laboratory testing cannot adequately predict long term behavior of filters used for ambient air filtration.

Therefore, Gore has deployed many test cabinets with our filters in extreme environments around the globe in order to accumulate data that characterize the behavior of our products under real life conditions. The valuable field data allows modelling of lifetime under various environmental conditions, and enables Gore to develop the most advanced filtration media for ambient air filtration.

GORE® Cooling Filters CF are the only air filters which are optimized for ambient air filtration and their operation lifetime at various pollution levels can be realistically approximated by a theoretical model supported by a broad base of real life data.
