Selection basis for cooling fan
Cooling fans are widely used in different industries, and the application requirements of each industry are inconsistent. The medical industry needs ultra-quiet, long-life fans, outdoor communication equipment needs waterproof fans, and cabinets and unmanned vehicles need large air volume fans. Wait... Then what should we consider when selecting a model?
