Industrial 225 mm Centrifugal Fan
This 225 mm backward-tilting centrifugal fan is built for industrial cooling duties. It runs on 230 VAC at 50 or 60 Hz and draws between 105 W and 155 W depending on line frequency. The impeller reaches 2 650 rpm at 50 Hz and 2 950 rpm at 60 Hz. A 3 µF, 450 VDB capacitor is required for operation.
Siemens Inverter Maintenance Teams
The unit serves as the primary cooling fan on Siemens inverter drives, removing heat from IGBT modules and auxiliary boards. It suits technicians who need a direct replacement for the original ebm-papst part. Buyers looking for a generic case fan, a different voltage, or a smaller footprint should look elsewhere because this model is purpose-built for that specific inverter platform.
Verify Voltage, Capacitor and Mounting
Confirm the supply is 230 VAC single-phase and that the existing capacitor matches 3 µF at 450 VDB. Check that the mounting pattern and clearances inside the inverter cabinet match the original fan dimensions. Ensure the ambient temperature range of -25 °C to 55 °C covers the installation environment.

Questions about this item
Will this 225 mm fan fit my Siemens inverter without extra brackets?
The R2E225-AT51-14 is the original Siemens inverter fan, so it matches the factory mounting points and requires no additional brackets.
Can I run this 230 VAC fan on a 50 Hz supply alongside older 60 Hz-rated equipment?
Yes, the motor is rated for both 50 Hz and 60 Hz at 230 VAC, so it will operate on either frequency without modification.
How do I verify the fan is working correctly after installation?
Measure the current draw; it should read approximately 0.46 A at 50 Hz or 0.64 A at 60 Hz with the 3 µF capacitor fitted.
