  • 230 V AC supply suits industrial and commercial installations
  • 2500 rpm speed with 62 dB noise level balances performance and sound
  • Ball bearing construction supports continuous operation in harsh environments
  • 190 mm width and 68.5 mm depth fit standard mounting spaces

Centrifugal Case Fan 230V AC

The ebmpapst R2E190-AO26-36 is a centrifugal blower designed for 230 V AC mains supply. It delivers 570 m³/h airflow at 2500 rpm with a noise level of 62 dB. The backward-curved impeller and ball bearings suit industrial cooling, medical equipment, rail vehicles and electronic enclosures.

230 V AC Mains Power Limits

Operating directly from 230 V AC removes the need for a separate DC power supply or motherboard header. The fan draws 58 W at free air and 75 W under load, so the circuit must handle the higher figure. No PWM or voltage speed control is provided; speed is fixed by line frequency and motor design.

Screw-Mount Installation Notes

The 190 mm square frame with 68.5 mm depth fits standard mounting holes for this form factor. Wiring requires live, neutral and earth connections to a mains-rated terminal block or connector. Common issues include forgetting the earth bond, using undersized cable for the 75 W draw, and restricting the backward-curve exhaust path.

Questions about this item

Should I pick the 58 W or 75 W rating for my build?

The fan draws 58 W at one operating point and 75 W at another; choose the lower figure for quieter running or the higher when maximum airflow is needed.

What does 570 m³/h mean once the fan is installed?

It moves up to 570 cubic metres of air per hour at 2500 rpm, so expect strong throughput in a 190 mm wide centrifugal housing.

How does the 230 V AC supply limit speed control options?

Running directly on 230 V AC mains means speed is fixed at 2500 rpm unless an external AC phase-cut or transformer controller is added.
