Fans R2E225-AX52-05Motor 225mm 230V 115/165W case fan
A 225 mm centrifugal case fan running on 230 V AC at 50/60 Hz with IP44 protection and 115/165 W power draw
- 225 mm blade diameter moves high air volumes
- 115/165 W power range handles demanding cooling loads
- 2700–3000 rpm speed delivers strong airflow performance
- IP44 protection resists dust and water splashes
- 230 V AC supply fits standard mains power
Industrial-grade centrifugal airflow
The ebmpapst R2E225-AX52-05Motor is a 225 mm AC centrifugal fan built for 230 V mains supply. It draws 0.51 to 0.72 A and delivers up to 35000 m³/h airflow for server racks, telecom cabinets and industrial enclosures that need continuous forced-air cooling.
Sustained thermal stability
The external-rotor motor sits inside the impeller so airflow cools the windings directly during non-stop operation. IP44 protection resists dust and splashing water, while 115 W at 50 Hz and 165 W at 60 Hz let the fan maintain 2700 to 3000 r/min without thermal throttling across long duty cycles.
Upgrade path for legacy AC blowers
This unit replaces older shaded-pole or PSC blowers of the same 225 mm diameter and 230 V rating when higher static pressure and full 0–100 % analog speed control are required. The jump is worthwhile when the existing housing cannot accommodate a scroll-less backward-curved design or when IP44 sealing becomes mandatory.

Questions about this item
How much power does the R2E225-AX52-05Motor draw when running continuously at 230 V?
The motor is rated at 115/165 W with a current draw of 0.51-0.72 A at 230 V, and it carries an IP44 protection rating for dust and splash resistance.
What mounting provisions and electrical connection does this 225 mm centrifugal fan require?
The unit is a bare centrifugal fan with a 225 mm blade diameter and external rotor motor; it needs a compatible scroll housing or ductwork and a 230 V AC supply capable of 50/60 Hz operation.
Will the 2700-3000 r/min speed of this fan be compatible with a legacy speed controller I already own?
The fan supports 100 % speed control via analog or serial interface, so an existing controller that outputs a suitable analog or serial signal can regulate the 2700-3000 r/min range.
