Original German ebmpapst 4374S 24V DC axial fan
This is a new ebmpapst 4374S series axial fan designed for 24 V DC operation. It measures 119 x 119 x 32 mm and uses a ball bearing for rotation. The unit draws 250 mA at 5 W and delivers an air flow of 169.9 m3/h at a noise level of 45 dB. It suits industrial enclosures or server chassis that provide a 24 V supply.
Best suited for 24 V DC systems
The fan fits builders who have a 24 V DC rail and need the 169.9 m3/h airflow in a 32 mm deep frame. It is not for systems that only provide a different voltage rail, nor for installations where the 45 dB acoustic output exceeds the permitted noise budget. The lead termination requires a compatible connector or direct wiring.
Deciding specification: 24 V DC supply voltage
The single figure that determines fit is the 24 V DC rating. If the target chassis or controller does not supply 24 V DC, the fan will not operate. All other dimensions and performance data are secondary to this electrical requirement.

Questions about this item
Will the 119 x 119 mm frame with 32 mm depth fit my case fan mounts?
The frame measures 119 mm by 119 mm and is 32 mm deep, so verify your case has matching square mounting holes and clearance for that thickness.
How do I connect the 24 V DC leads without damaging the fan?
Connect the lead wires to a 24 V DC source observing the correct polarity; the fan includes reverse-polarity and lock protection, but wiring it backwards can still prevent operation.
When should I expect to replace the ball-bearing fan?
Ball bearings typically last tens of thousands of hours; plan replacement when noise rises above the rated 45 dB or airflow drops below 169.9 m³/h.
