SKU CH-7EBS-8HT3A MPN 4712KL-05W-B40Size

A 24 V axial case fan delivering 112 CFM at 3100 RPM with 47 dBA noise

  • Delivers 112 CFM airflow for effective component cooling
  • Runs at 3100 RPM to move high air volume
  • Operates on 24 V 0.48 A for stable power draw
  • Produces 47 DBA noise for moderate acoustic levels
  • Built as an original NMB unit for industrial-grade reliability

Industrial-grade 24 V axial fan

This 120 mm square fan runs on 24 V DC and draws 0.48 A at its 0.34 A rated current, delivering 8.16 W of cooling power. It targets equipment builders who need reliable airflow in medical devices, rail vehicles, inverter drives, hotel systems and industrial cleaning gear.

112 CFM airflow with 0.33 in H2O static pressure

At 3100 RPM the impeller moves 112 CFM while developing 0.33 in H2O of static pressure, enough for ducted enclosures and heat-exchanger stacks. The flow drops off when system resistance exceeds the rated pressure curve, so very restrictive filters or long duct runs will starve the fan.

47 dBA noise at full speed

Measured acoustic output is 47 dBA when the motor spins at 3100 RPM, a level suited to plant rooms and equipment cabinets rather than quiet offices. Power draw stays at the rated 8.16 W under normal load, and the 240 g rotor mass keeps vibration low in continuous operation.

Questions about this item

Will the 24V 0.48A specification match the power header on my existing ABB ACS800 inverter?

The fan is rated for 24V at 0.48A with a rated current of 0.34A, matching the original NMB specification for the ACS800 dedicated cooling slot.

How can I confirm the 3100RPM 112CFM airflow is reaching the drive heatsink after installation?

Measure exhaust temperature drop across the heatsink and listen for the 47DBA acoustic signature; steady airflow at that noise level indicates the impeller is spinning at full rated speed.

Does the 120*120*38mm unit ship with mounting screws or a wiring harness for the inverter bay?

The listing covers the fan module only; mounting hardware and any connector adapter for the ACS800 bay must be sourced separately.
