Industrial 24 V axial fan

This 24 VDC axial fan from EBM-Papst Industries Inc belongs to the 6400 series and measures 172 mm by 150 mm by 50.8 mm. It draws 1.1 A at 26 W and spins at 4000 RPM to deliver 282.5 CFM of airflow. The ball-bearing design operates from -20 °C to 55 °C and produces 63 dB(A) of noise.

Server and industrial chassis builders

The fan suits 24 V DC systems that can accommodate its rectangular 172 mm by 150 mm footprint and 50.8 mm depth. Builders working with standard 12 V PC headers or compact cases that only accept smaller square frames will not be able to use this unit.

24 VDC rated voltage

The single specification that determines fit is the 24 VDC rated voltage; the fan requires a 24 V DC power source and two-terminal connection. Without a 24 V supply the fan will not operate.

Questions about this item

How do I mount the 172 mm by 150 mm frame and connect the 24 VDC supply to the two terminals?

Align the four corner holes of the 172 mm × 150 mm housing with the chassis fan mounts, secure with M4 screws, then attach the two power terminals to a 24 VDC source observing polarity.

When will the ball bearings require replacement under continuous 4000 RPM operation?

Ball bearings in the 6400 series are rated for tens of thousands of hours at 4000 RPM; plan inspection after two to three years of 24/7 use and replace if noise rises above the specified 63 dB(A).

At what ambient temperature does the fan reach its thermal limit during sustained 26 W load?

The operating ceiling is 55 °C (131 °F); sustained 26 W draw at or above this ambient will trigger thermal protection and reduce airflow below the rated 282.5 CFM.
