EBM centrifugal fan with backward-curved blades

The EBM R2E250-AV62-05Motor is a 230 V AC centrifugal fan built for cabinet and air-conditioning installations. Its external-rotor motor sits inside the 250 mm impeller for compact integration and direct motor cooling. The backward-curved blade design runs as a free-wheeling unit without a scroll housing. It delivers up to 35000 m³/h airflow at 2650 RPM.

Suited for industrial cabinet cooling

Engineers specifying forced-air cooling for dense enclosures or ducted HVAC modules will match the 75 W nominal power and 0.82 A draw at 230 V. The fan supports 100 % speed control via analog or serial interfaces for precise thermal management. Buyers needing a forward-curved blower with integrated scroll housing or a low-voltage DC variant should look at something else.

75 W motor headroom for continuous duty

At 175 W peak the motor absorbs start-up transients while the 75 W rating defines steady-state thermal limits. The 250 mm blade diameter moves high volume against moderate static pressure typical of filter banks and heat-exchanger arrays. Beyond the rated airflow curve the impeller stalls and motor current rises sharply, so duct resistance must stay within the published performance envelope.

Questions sur cet article

What voltage supply is required for the 230V centrifugal fan?

The fan operates on a 230V AC supply drawing 0.82A at full load.

Can the 2650 RPM fan speed be adjusted using an analog interface?

Yes, the external rotor motor supports 100% speed control via an analog interface.

How do I verify the 250mm impeller is moving air correctly after installation?

Check for airflow up to 35000 m³/h and confirm the motor runs at 2650 RPM without vibration.
