Fans 1608KL-05W-B39Size 24V 0.07A case fan

SKU CH-8MBD-NF7JK MPN 1608KL-05W-B39Size

A 24 V DC case fan measuring 40 mm square by 20 mm thick spins at 6500 RPM to move 7.4 CFM at 25.5 dBA

  • Runs at 25.5 dBA for quiet operation
  • 6500 RPM delivers 7.4 CFM airflow
  • 24 V DC at 0.07 A draws 1.92 W
  • Double NMB-MAT bearings rated for 50,000 hours
  • MTBF of 180,000 hours ensures long-term reliability

40mm 24V case fan for industrial cooling

This 40 by 40 by 20 millimetre axial fan runs on 24 volt DC power and draws 0.07 ampere. It delivers 7.4 cubic feet per minute of airflow at 6500 revolutions per minute with a static pressure of 42.2 pascal. The unit is built with a Japanese NMB-MAT double bearing and rated for 50000 hours of service life at an ambient range of minus 20 to 75 degrees Celsius.

Replaces worn 24V axial fans in tight enclosures

The fan fits the same 40 millimetre square footprint used in many servo amplifiers, medical devices, rail vehicle drives and industrial cleaning equipment. Upgrading is worthwhile when the original unit exceeds its rated hours, develops bearing noise above 25.5 decibel A or can no longer maintain the required 0.21 cubic metres per minute airflow. It is not suited for builds needing larger frame sizes or higher voltage rails.

Simple two-wire installation with polarity care

Connection uses standard red and black leads for 24 volt supply; reverse polarity will prevent operation. The 25 gram weight and compact depth allow mounting in crowded chassis without structural reinforcement. Common issues include forgetting to verify the 1.92 watt power budget on the driver board and overlooking the 180000 hour MTBF rating when scheduling preventive maintenance.

Questions about this item

Will the 40 mm square footprint with 20 mm thickness fit my servo amplifier enclosure?

The frame measures 40 mm by 40 mm and is 20 mm thick, so verify your chassis cut-out matches those dimensions before ordering.

Which wire polarity do I connect to the 24 V supply to avoid damaging the motor?

Connect the red lead to positive and the black lead to negative on a 24 V DC source; reversing them will prevent the fan from starting.

When should I plan to replace the fan given the rated 50 000 hour service life at 25 °C?

At continuous operation the bearing is rated for 50 000 hours at 25 °C; schedule replacement once you approach that runtime or if noise rises above 25.5 dBA.
