4 cm 12 V switch fan for compact cooling

The TSUJ 4028 is a 4 cm axial fan rated for 12 V and 0.81 A. It delivers large air volume in a small frame, making it suitable for tight enclosures, appliance retrofits or electronics chassis that need targeted airflow. The integrated switch allows simple on-off control without external wiring.

Sustained high-speed operation at rated current

Running continuously at 12 V and 0.81 A, the motor maintains steady rotational speed and consistent airflow without thermal throttling. Bearing noise remains stable over long periods, and the switch contact handles repeated cycling. The unit is built for continuous duty rather than short bursts.
