German Ebm-Papst 4414F/2M 24V DC Axial Fan

This original German Ebm-Papst 4414F/2M is a compact DC axial fan built for cooling electronics, medical gear, rail vehicles and industrial equipment. It runs on a 24 V DC supply and draws 3.2 W. The PBT housing and PA impeller are paired with a ball-bearing design for long service life.

Installing the 12025 Fan with Polarity Protection

The unit uses a standard two-wire 24 V DC connection; reverse-polarity protection prevents damage if the leads are swapped. Lock-prevention circuitry helps the motor start reliably after long idle periods. Verify that your system provides a stable 24 V rail before wiring the fan.

The 24 V 3.2 W Rating Decides Compatibility

This model only operates on a 24 V DC source rated for at least 3.2 W. It will not run on 12 V or 5 V lines found in typical desktop PCs. Buyers who need a fan for standard motherboard headers or lower-voltage chassis should choose a different voltage variant.

Questions about this item

How can I confirm the 4414F/2M 12025 fan is spinning correctly after connecting it to a 24 V DC supply?

Apply 24 V DC power; the motor should start immediately and run smoothly. The ball-bearing design and lock-prevention feature prevent stalling, so steady rotation at the rated 3.2 W draw indicates normal operation.

What is included with the 4414F/2M 12025 fan and what must I source separately?

The package contains the axial fan unit only — PBT housing, PA impeller, and integrated ball-bearing motor with polarity-reverse protection. You must provide a 24 V DC power source, mounting screws, and any wiring or connectors.

Which voltage version of the 4414F/2M 12025 should I choose for a 24 V DC cooling circuit?

This model is the 24 V DC variant rated at 3.2 W. Select it when your system supplies 24 V DC; other voltage versions are not covered by this listing.
