  • 31 model reference identifies the AD0424 HB-B31 variant

40 mm 24 V DC case fan

This 40 mm fan runs on 24 V DC power and uses a double ball bearing for continuous operation. It fits equipment that calls for the 4028 frame size and AD0424HB-B31 specification. The compact design targets converters, industrial chassis and other tight spaces that need reliable airflow.

Double ball bearing reliability

The double ball bearing reduces friction and resists dust better than sleeve alternatives, extending service life in 24/7 environments. Buyers who need a larger frame, a different voltage or a PWM control signal should look elsewhere because this unit is fixed at 24 V with a two-wire connection.

Questions about this item

What does the 24V rating mean for installing this fan in a standard PC?

The fan requires a 24V DC power source, which is not supplied by typical motherboard headers.

How does the 4028 form factor affect fitment in a case?

The 4028 designation indicates a 40 mm square frame with 28 mm thickness, so it only fits mounts designed for that size.
