Compact 70 mm DC fan for 24 V systems

The 7020 frame measures 70 by 70 by 20 mm and runs on 24 V DC at 0.14 A. Double ball bearings support continuous rotation in industrial chassis, embedded appliances or custom cooling loops. Three wires provide speed monitoring for automated thermal control.

Steady airflow with bearing durability

Double ball bearings reduce wear compared with sleeve alternatives, maintaining consistent speed during extended operation. Rated current of 0.14 A at 24 V keeps power draw predictable under sustained load. The 3-wire tachometer signal allows the host system to detect slowdown before temperatures rise.
