SKU CH-QN06-S4MKJ MPN 3615KL-05W-B50Size

A 90 mm DC 24 V axial fan delivering 3400 RPM, 40.2 CFM airflow and 35.0 dBA noise for industrial cooling

  • Quiet operation at 35.0 d-BA noise level
  • Efficient cooling with 40.2 CFM airflow
  • Reliable 24 V DC power at 3.12 W
  • Compact 90*90*38 mm axial design
  • Waterproof build suits industrial and rail use

Purpose-built cooling component

The NMB 3615KL-05W-B50 is an axial fan built for ABB ACS800 inverter drives and other industrial equipment that need reliable airflow in a 90 by 90 by 38 millimetre frame. It suits engineers and maintenance teams who need a direct replacement for waterproof cooling in rail, medical, new-energy vehicle or hotel infrastructure applications.

Wiring and mounting practicalities

A two-wire lead 18 centimetres long carries red for positive and black for negative at DC 24 volts, drawing 0.32 amps and 3.12 watts. The short pigtail means the installer must plan for a nearby terminal block or splice, and the line colours remove polarity guesswork during field swaps.

Environmental resilience and daily fit

Rated IP waterproof, the fan withstands wash-down and outdoor exposure while delivering 40.2 CFM at 3400 RPM with 40.2 Pa static pressure and 35.0 dBA noise. The compact square footprint fits tight enclosures where larger blowers cannot mount, and the axial design pushes air straight through the chassis without ducting changes.

Highlights

  • Quiet operation at 35.0 d-BA noise level
  • Efficient cooling with 40.2 CFM airflow
  • Reliable 24 V DC power at 3.12 W
  • Compact 90*90*38 mm axial design
  • Waterproof build suits industrial and rail use

Questions about this item

How often should I plan to replace the 2-wire DC 24 V axial fan running at 3400 RPM?

The fan is rated for continuous industrial use; plan replacement when airflow drops below 40.2 CFM or bearing noise exceeds 35.0 dBA.

What is the first limit reached when the 3615KL-05W-B50 runs at full speed for extended periods?

The 3.12 W power draw and 40.2 Pa static pressure ceiling are reached before thermal limits at 24 V.

How much noise and heat does the 90×90×38 mm waterproof fan produce in 24/7 operation?

It emits 35.0 dBA and dissipates 3.12 W, with a 18 cm lead keeping the connector away from the hot exhaust.
