  • 2 800 rpm at 50 Hz, 3 250 rpm at 60 Hz

Centrifugal blower for Siemens inverter cooling

This ebm-papst centrifugal blower is an original replacement component designed for Siemens inverter systems. It handles heat dissipation from high-power IGBT modules and supporting electronic boards. The backward-curved blade design supports compact installation and long service life in industrial environments.

Verify voltage wiring

Confirm the supply matches the 380 VAC or 440 VAC Y-wiring specification and that the operating frequency is 50 Hz or 60 Hz. The motor is rated for ambient temperatures between -25 °C and 50 °C. Current draw reaches 0.18 A at 50 Hz and 0.20 A at 60 Hz, with power consumption of 75 W or 110 W respectively.

Genuine ebm-papst build

The unit uses the M2D068-DF motor and runs at 2800 rpm on 50 Hz or 3250 rpm on 60 Hz. Backward-curved blades reduce noise while maintaining airflow pressure for dense component stacks. Direct mounting replaces the failed factory fan without modification, restoring reliable cooling for the inverter assembly.

Questions about this item

What comes with the R2D220-AB02-10 blower and is any extra hardware needed?

The unit is supplied as a complete centrifugal blower with integrated motor M2D068-DF. No separate mounting brackets, wiring harnesses or controllers are mentioned, so plan to reuse the original Siemens inverter fixings and power connections.

Which voltage and frequency version of the R2D220-AB02-10 should I select?

The nameplate lists 380/440 VAC wired in Y configuration for both 50 Hz and 60 Hz mains. Choose this single variant when replacing the large bottom fan in a Siemens inverter designed for that supply.

What does the 75 W rating mean once the blower is installed in the inverter?

At 50 Hz the motor draws 0.18 A and runs at 2800 rpm consuming 75 W; at 60 Hz it draws 0.20 A, reaches 3250 rpm and consumes 110 W. Operating range is -25 °C to 50 °C ambient.
