Fans R2E175-AC91-05 65W turbo centrifugal case fan

SKU CH-Q5TF-7C3DC

Centrifugal case fan running at 2550–2850 rpm with 65–70 W power draw and up to 35000 m³/h airflow

  • High airflow up to 35000 m³/h for demanding cooling
  • 65 W power draw at 400 VAC 50 Hz operation
  • External rotor motor design enables compact installation
  • Sturdy steel plate construction ensures durability
  • 100 % speed control via analog or serial interface

Industrial centrifugal fan for 400 VAC systems

This ebmpapst R2E175-AC91-05 is a turbo centrifugal fan rated for 400 VAC two-phase supply at 50 or 60 Hz. It draws 0.18 A at 50 Hz and 0.20 A at 60 Hz while consuming 65 W and 70 W respectively. The unit suits industrial enclosures and rack cabinets that require high-pressure airflow from a compact external-rotor motor.

Sustained operation at 2550 to 2850 rpm

Speed stabilises at 2550 rpm on 50 Hz and 2850 rpm on 60 Hz, delivering up to 35000 m³/h through the forward-curved impeller. Power consumption remains steady at the rated 65 W or 70 W without the short-burst peaks seen in axial designs. The 0.5 µF 700 VDB capacitor maintains phase balance during continuous duty.

Thermal and acoustic profile in normal use

Ambient temperature range spans -25 °C to 45 °C at 50 Hz and -25 °C to 70 °C at 60 Hz, allowing deployment in harsh plant rooms. Motor cooling is forced by the impeller itself, so housing temperature tracks airflow rather than stalled air pockets. Noise stays low for a centrifugal design because the blades are forward-curved and the steel scroll housing dampens vibration.

Questions about this item

How much power does the R2E175-AC91-05 draw when running continuously at 50 Hz?

At 50 Hz the motor consumes 65 W and draws 0.18 A from a 400 VAC supply, with a 0.5 µF 700 VDB capacitor fitted.

What mains supply and wiring does this centrifugal fan require?

It needs a three-phase 400 VAC connection at 50 or 60 Hz, plus a 0.5 µF 700 VDB run capacitor wired in series with the motor.

Will the 2550 rpm speed at 50 Hz match the airflow curve of my existing 2850 rpm 60 Hz units?

At 50 Hz the fan runs at 2550 rpm and at 60 Hz it reaches 2850 rpm, so the same model covers both frequencies with a predictable speed shift.
