Atrenne’s fan guards (patent pending) product line are designed with Atrenne’s advanced MicroVent® Technology. This product line addresses the increasing problem in the electronics industry of electronic noise (EMI) escaping from the cooling path of complex mechanical enclosures. Atrenne’s MicroVent technology provides the most open area for air flow providing improved cooling of electronic components while improving the EMI integrity of the system. Each guard is designed around industry standard fan geometry in 2, 3 & 5 mm thickness to support each customers’ specific application. Available in standard 80mm and 120mm sizes, as well as custom sizes, these fan guards easily attach to any embedded computer fan with machine screws for little to no down-time. Application specific EMI testing using MicroVent has been done up to 40 Gig providing excellent results. Along with the positive EMI results we have air flow testing on our MicroVent fan guards versus standard off the shelf industry solutions. Atrenne has also conducted air flow test on MicroVent versus industry standard EMI gasket solutions currently used in the industry.
