Industrial Cooling Fan 24V 0.70A 12CM

The Fans 1238HH24B-WDB is a 24 volt axial case fan drawing 0.70 amps for industrial drive and equipment cooling. It suits integrators building medical, rail, new-energy vehicle or supermarket automation systems that require a 12 centimetre form factor. The unit is supplied new and ready for direct mounting in compatible chassis.

Replaces Legacy 24V Axial Units

This fan replaces older 24 volt axial fans of similar frame size when the original part number matches 1238HH24B-WDB or 3HAC 029105-002/01. The upgrade is worth it when the existing fan has failed, shows bearing noise or cannot meet the airflow demand of the drive enclosure. Compatibility must be verified against the equipment manufacturer's service list before fitting.

Handles Drive Enclosure Airflow

The fan delivers continuous airflow for drive cooling in medical, rail and industrial cleaning cabinets where ambient temperatures stay within the rated range. It runs out of headroom when static pressure exceeds the curve for this frame size or when the system demands higher volumetric flow than a single 12 centimetre axial unit can provide. Multiple units in parallel may be required for larger enclosures.

Questions about this item

What mounting holes does the 1238HH24B-WDB 12CM fan use?

The fan follows a standard 120 mm square frame pattern with four corner holes for M3 or M4 screws, matching typical case and radiator mounts.

Which wire goes where when wiring the 24V 0.70A leads?

Connect the red lead to +24 V and the black lead to ground; reversing them will prevent the motor from starting.

When should the 3HAC 029105-002/01 fan be replaced?

Replace the unit when bearing noise becomes audible, airflow drops noticeably, or the rotor no longer spins freely at 24 V.
