140mm centrifugal turbo fan with forward-curved blades in metal housing

Fans

Fans R2E175-AC77-05 230V 140mm centrifugal turbo fan

SKU CH-62D7-F2TY4

230 V AC centrifugal turbo fan with 140 mm impeller, 2600–2900 rpm and 55–65 W draw

  • Operates on standard 230 VAC mains power
  • Runs at 2600 rpm (50 Hz) or 2900 rpm (60 Hz)
  • Draws only 55 W at 50 Hz and 65 W at 60 Hz
  • Delivers airflow up to 35000 m³/h
  • Withstands ambient temperatures from –25 °C to +65 °C

Industrial-grade centrifugal cooling

The ebm-papst R2E175-AC77-05 is a 140 mm centrifugal turbo fan built for 230 V AC mains supply. It targets system integrators and maintenance teams who need reliable forced-air cooling inside rack enclosures, industrial PCs or HVAC ducting where a scroll-housing blower is required.

Steel scroll housing and external-rotor motor

The forward-curved impeller sits inside a sturdy steel scroll that directs airflow without extra ductwork. An external-rotor motor places the windings in the impeller hub, giving forced electronic cooling and a compact footprint. Capacitor-rated 1.5 µF at 450 V DB is included for single-phase operation.

2600 rpm at 50 Hz delivers up to 35000 m³/h

At 50 Hz the fan spins at 2600 rpm, draws 0.25 A and consumes 55 W while moving up to 35000 m³/h. At 60 Hz speed rises to 2900 rpm, current to 0.29 A and power to 65 W. Operating range spans -25 °C to 50 °C at 50 Hz and -25 °C to 65 °C at 60 Hz, so builders needing higher-temperature margins must verify the frequency match.

Questions about this item

How often should I replace the 1.5 µF 450 V capacitor used for starting and running this fan?

The motor draws 0.25 A at 50 Hz and 0.29 A at 60 Hz; the capacitor is rated for continuous operation at those currents and at ambient temperatures up to 65 °C, so replacement is only needed if measured capacitance drops below 1.5 µF or the fan fails to start.

Will the 55 W / 65 W power rating or the 65 °C ambient limit become the first constraint when the fan runs continuously?

At 50 Hz the fan uses 55 W and is rated for ambients up to 65 °C; at 60 Hz power rises to 65 W while the same 65 °C limit applies, so the temperature ceiling is reached before the power figure changes.

How loud and how hot does the 140 mm centrifugal impeller get when it spins at 2600 rpm all day?

The external-rotor motor sits inside the impeller, giving forced electronic cooling; at 2600 rpm the motor stays within its 65 °C ambient rating and the forward-curved blades run at the low-noise level ebm-papst specifies for this design.
