SKU CH-S1F4-7668H MPN 3110KL-05W-B69

80mm axial case fan runs on 24V DC, spins at 3400RPM, delivers 40.2CFM airflow at 35DBA

  • Quiet 35 dBA noise for focused work
  • 2 CFM airflow cools components efficiently
  • 24 V DC input fits industrial systems
  • 3400 RPM speed delivers strong pressure
  • Light 95 g build eases installation

NMB 24 V inverter fan

This 80 mm axial fan runs on a 24 V DC supply with a working range from 10.0 V to 27.6 V. It draws 0.18 A rated current and spins at 3400 RPM to deliver 40.2 CFM airflow. The unit weighs 95 g and produces 35 dBA noise. It suits industrial, medical or embedded cooling tasks where a compact 24 V source is available.

80×80×25 mm frame with two-wire lead

The plastic housing measures 80 mm square by 25 mm thick and uses a standard two-wire connection for power. No PWM or tachometer wire is present so speed control relies on voltage variation. Mounting holes accept common 80 mm fan screws or clips. The lightweight build eases installation in tight chassis or ducting.

Check voltage and connector before ordering

Your system must provide a stable 24 V DC rail within the 10.0 V to 27.6 V window and a two-pin header or solder points for the fan leads. There is no speed signal feedback so the controller cannot monitor rotation. Buyers needing PWM control, a three or four-pin header, or 12 V operation should look elsewhere.

  • Quiet 35 dBA noise for focused work

Questions about this item

What voltage range does the 24 V DC fan actually accept?

The working voltage range is 10.0 V to 27.6 V DC, so the fan will start and run anywhere within that window.

What are the exact mounting dimensions for the 3110KL-05W-B69?

The frame measures 80 mm by 80 mm with a 25 mm thickness, matching standard 80 mm case-fan screw spacing.

How do I wire the two-lead connector without reversing polarity?

Connect the red lead to 24 V DC positive and the black lead to ground; reversing them will prevent the fan from spinning.
