Centrifugal fan with 168 W motor, 200–240 V AC supply and airflow up to 35000 m³/h for air purification systems

  • High airflow up to 35000 m³/h for effective purification
  • EC motor runs on 200–240 V at 50/60 Hz for flexible installation
  • Low 168 W draw and 1.4 A current keep running costs down
  • Operates reliably from -25 °C to 60 °C in harsh environments
  • Compact external-rotor design with forced electronic cooling saves space

German-engineered centrifugal air purifier

The Fans R3G280-RB02-03 is a new centrifugal air purifier built around an ebm-papst external-rotor motor. It suits installers and facility managers who need a compact, high-flow fan for commercial or industrial ventilation systems.

Single-phase 200–240 VAC operation

The unit runs on single-phase mains at 50 or 60 Hz, drawing 1.4 A at a nominal 230 VAC. Power consumption is rated at 168 W, and the motor is specified for ambient temperatures from -25 °C to 60 °C, defining the electrical and thermal envelope for any installation.

Backward-curved impeller with speed control

The backward-curved blades operate as a free-wheeling fan without a scroll housing, while the external rotor design provides forced motor cooling. A steel plate construction adds rigidity, and the motor supports 100 % speed control via analog or serial interface for straightforward integration.

Questions about this item

Should I choose the 200 V or 230 V nominal voltage version for my installation?

The unit operates on a single 1~ phase with a nominal range of 200 .. 240 VAC, so the same model covers both voltages.

What does the 168 W power rating mean for actual airflow in my system?

At 168 W the motor draws 1.4 A and delivers up to 35,000 m³/h through the backward-curved centrifugal impeller.

How does the 100 % speed control interface limit what I can do with the fan?

An analog or serial interface gives full 0–100 % speed control, allowing precise airflow adjustment without extra hardware.
