Fans R2E220-AA40-80 Centrifugal Case Fan 230V 85/100W 2700rpm

SKU CH-22GN-KXVS0

A 230 V AC centrifugal case fan running at 2700 rpm with 85 to 100 W power draw for inverter cooling

  • Original German ebmpapst engineering ensures reliable industrial cooling
  • 230 V AC single-phase motor runs directly from mains without extra power supply
  • Backward-curved centrifugal impeller delivers up to 35000 m³/h airflow for high-volume intake
  • CE and UL 2111 approvals confirm compliance with European and North American safety standards
  • Wide -25 °C to 55 °C operating range suits harsh ambient environments

Industrial Centrifugal Fan for 230 V Systems

The Fans R2E220-AA40-80 is an ebm-papst centrifugal case fan built for 230 VAC single-phase operation. Its backward-curved impeller and external-rotor motor deliver airflow up to 35000 m³/h without a scroll housing. The unit is CE and UL 2111 approved and rated for ambient temperatures from -25 °C to 55 °C, making it suitable for inverter cooling and forced-air electronics enclosures.

Steady-State Airflow at 50 and 60 Hz

At 50 Hz the motor runs at 2600 rpm drawing 85 W and 0.38 A; at 60 Hz it reaches 2700 rpm with 100 W and 0.43 A. Because the external-rotor design couples the rotor directly to the impeller, speed and flow remain stable during continuous duty rather than dropping after a short burst. The 3 µF (50 Hz) or 2 µF (60 Hz) run capacitor at 400 VDB maintains consistent torque across the voltage cycle.

Thermal Range, Acoustic Profile and Power Draw

The fan operates continuously between -25 °C and 55 °C with no minimum back-pressure requirement. Power consumption stays at 85 W (50 Hz) or 100 W (60 Hz) under normal load, with starting current of 0.54 A at 50 Hz and 0.52 A at 60 Hz. The compact steel housing and integrated motor keep the acoustic signature low for industrial environments while providing forced electronic cooling.

Questions about this item

How much heat and power will the 230 V 85 W motor add when running continuously?

The motor draws 0.38 A at 50 Hz and 85 W, rising to 0.43 A and 100 W at 60 Hz, so waste heat scales with the load you apply.

What external capacitor must I supply for the 230 V single-phase motor?

A 3 µF 400 VDB capacitor is required at 50 Hz; a 2 µF 400 VDB unit covers 60 Hz operation.

Will the 2700 rpm backward-curved impeller fit inside a legacy 220 mm mounting frame?

The model designation R2E220 indicates a 220 mm frame size, matching standard legacy cut-outs.
