Industrial Cooling Fan

The Nidec M34691-58 is a 9225 frame DC axial fan built for continuous duty in medical equipment, rail vehicles, industrial drives and hotel infrastructure. It runs on a 24 V supply and draws 0.33 A, making it suitable for 24 V DC power buses found in automation cabinets and new-energy vehicle systems.

Three-Line Speed Control

A three-wire interface provides tachometer feedback and PWM or voltage speed control so the host system can regulate airflow precisely. The inverter-driven motor maintains stable rotation across the control range without the acoustic hunting common in simpler two-wire designs.

Low-Noise Continuous Operation

The centrifugal-style blade geometry and precision bearing deliver quiet airflow at the rated 24 V input, keeping acoustic signature low in noise-sensitive medical and hotel environments. Power draw stays at 0.33 A under normal load, so thermal margins in sealed enclosures remain predictable.

Questions about this item

How much current does the 24 V M34691-58 fan draw once it is running in a system?

The fan is rated at .33 A at 24 V DC, so that is the steady-state current it will draw when powered.

What does the three-line connection on the M34691-58 provide for control and monitoring?

The three lines give power, ground and a speed-report or PWM line, letting the host read RPM or adjust speed without a separate sensor.

Will the 9225 frame fit a standard 92 mm square mounting pattern?

The 9225 designation matches a 92 mm square frame with 25 mm thickness, which aligns with the common 92 mm mounting holes.
