4028 24V fan for compact cooling

This 40 mm case fan runs on 24 V and draws 0.16 A through a standard three-wire connector. It is built for tight chassis, industrial enclosures or replacement cooling where a small 24 V unit is specified. The double ball bearing design targets longer service life in continuous operation. Buyers who need a larger frame, PWM control or a different voltage should look elsewhere.

Double ball bearing and three-wire simplicity

The double ball bearing reduces friction compared with sleeve alternatives, helping the fan maintain consistent speed over time. The three-wire lead supplies power, ground and a tachometer signal so the host can monitor rotation without PWM complexity. No mounting screws, adapters or software are bundled with the unit.

Questions about this item

Will the double ball bearings need scheduled replacement?

Double ball bearings are rated for long continuous operation and generally outlast sleeve designs without a fixed replacement interval.

What limits sustained operation before the motor overheats?

The fan draws 0.16 A at 24 V, so thermal limits are reached only if airflow is blocked or voltage exceeds the rated 24 V.
