Fans R2E190-AE77-B8 190mm 230V 105W centrifugal case fan

SKU CH-SPH7-N105T

A 190 mm centrifugal case fan delivering 650 m³/h airflow at 2350 rpm with 62 dB(A) noise and 57,500-hour rated life

  • 190 mm impeller moves 650 m³/h of air for strong case cooling
  • 230 VAC operation with 105 W motor plugs directly into mains power
  • 57,500-hour rated life at 40 °C reduces replacement frequency
  • Maintenance-free double ball bearings run quietly at 62 dB(A)
  • Wide 175–230 V input range tolerates voltage fluctuations

Industrial Centrifugal Air Mover

The Fans R2E190-AE77-B8 is a 190 mm AC centrifugal fan rated for 230 V mains supply. It draws 105 W at 0.26 A and delivers up to 650 m³/h of airflow at a maximum static pressure of 370 Pa. The unit suits industrial enclosures, server cabinets and equipment racks that need forced convection directly from line voltage.

Mains-Powered Drop-In Cooling

No separate DC supply or motherboard header is required; the fan connects straight to 230 VAC via a 450 mm flying lead with a bare TR64 plug end. Its voltage range of AC 175 V to 230 V and 50/60 Hz tolerance lets it run on unstable grid power without extra regulation. The integrated external-rotor motor keeps the assembly compact, freeing internal volume for other hardware.

57,500-Hour Service Life at 40 °C

Double ball bearings rated for an estimated 57,500 hours at 40 °C give long intervals between replacements. The glass-fibre reinforced PBT housing and PA impeller withstand ambient temperatures from -25 °C to +55 °C. Noise reaches 62 dB(A) at full speed, so the fan is less suited to quiet workstations or noise-sensitive studio builds.

Questions about this item

What temperature limit stops the R2E190-AE77-B8 running continuously?

The fan is rated for ambient temperatures up to +55 °C; sustained operation above that will trip its thermal protection.

How loud and how much power does it draw when running all day?

It produces 62 dB(A) and draws 105 W at 230 VAC once up to speed.

Which capacitor must be fitted before the fan will start?

A 2.0 µF / 400 VDB start capacitor is required and is not included with the fan.
