NDLIULEI 6224N 24V 18W 3400 RPM Fan

The NDLIULEI 6224N is a DC axial case fan manufactured by ebm-papst. It operates at 24 VDC with a power rating of 18 W and a maximum current of 710 mA. The fan runs at a fixed speed of 3400 RPM and delivers an airflow of 241.3 m3/h. It uses a ball bearing for motor operation.

Suited for 24 VDC server and communication cabinets

This fan fits equipment that provides a 24 VDC supply and accepts a 172 mm square frame with a 51 mm depth. The IP20 rating and 55 dBA noise level make it appropriate for rackmount or cabinet environments. It is not for builders who need a different operating voltage, variable speed control, a smaller frame size or a lower noise profile for quiet desktop use.

Key specification: 24 VDC fixed-speed operation

The single specification that decides fit is the 24 VDC nominal voltage combined with a fixed 3400 RPM speed. The unit has no PWM or voltage regulation feature described in the data, so speed cannot be adjusted by the host system. Verify that your chassis or controller supplies 24 VDC and does not require variable fan control before purchase.

Questions about this item

How often will the ball bearing need replacement?

The ball bearing is rated for continuous operation at 3400 RPM without a scheduled replacement interval.

What thermal limit appears first during sustained 24 VDC operation?

The motor draws a maximum of 710 mA at 18 W, so the current limit is reached before any thermal throttle point.

How loud is the fan when running all day at 3400 RPM?

It produces 55 dBA at full speed with a 241.3 CFM airflow through the 172 mm square frame.
