Filters Keep Outdoor Enclosures Cool And Clean

For improving reliability in systems housed in outdoor enclosures, the GORE Cooling Filters rely on ambient air to temper electronic components and the company’s membrane technology to protect against corrosive particles, sand, or salty environments. Direct-air-cooling systems using the filters reportedly have fewer mechanical parts, are easier to integrate, and require less maintenance. The filters also promise to reduce operating costs as they use less energy than mechanical systems, reduce overall cabinet size, and improve MTBF. The proprietary, expanded polytetrafluoroethylene membrane allows cool, clean air to flow into the cabinet while screening out harmful contaminants and has a 99% particle-filtration efficiency at level of 1 cm/s. Additionally, the filters can be customized to fit small to large basestation units. W. L. GORE & ASSOCIATES INC., Elkton, MD, (800) 638-5300.
