F-251-1

Aearo Technologies LLC, a 3M company's F-251-1 represents the next evolution in Fans - Accessories technology, optimized for industrial-grade cooling solutions. This robust component incorporates military-spec materials to withstand harsh operating conditions while delivering consistent thermal regulation performance. Its innovative design addresses three critical challenges: vibration isolation, corrosion resistance, and EMI shielding.Functioning as a specialized Fan Mount, this accessory exceeds IP68 protection standards for dust/water ingress. The aerospace-grade aluminum construction provides 50% greater torsional strength than conventional brackets, making it ideal for mobile base station applications.Engineered to accommodate Flange Thickness 9 ~ 10mm, Hole Diameter 2.5 ~ 3.7mm, this solution features a unique spring-loaded retention system that compensates for thermal expansion. The nickel-plated contacts maintain stable electrical connectivity even in high-humidity environments up to 95% RH.The 1.38" (35.0mm) dimension has been thermally optimized to prevent heat soak in continuous operation scenarios. Precision-machined tolerances of 0.05mm ensure perfect alignment with OEM fan housings, reducing turbulent airflow by up to 30%.
