This 40x40x28mm high-speed DC fan is designed for demanding thermal environments where compact size, high static pressure, and precise speed control are essential. It is ideal for use in telecom base stations, industrial power inverters, battery management systems (BMS), embedded computing devices, and fan trays in rackmount servers or control panels. With 24V input and PWM+FG support, it ensures reliable airflow in tightly packed or high-resistance environments such as inverter cabinets, high-density modules, and energy storage systems.
