AC to EC Replacement — R2E EC Centrifugal

The ebm-papst R2E225-RA92-20 from the EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including R2D, R4E. Key benefits:

35-50% energy savings — EC motor variable speed matches airflow demand precisely
Identical mm mounting — no ductwork modification needed
0-10V/PWM speed control — integrates with Building Management Systems
40,000+ hour bearing life — double the typical AC fan lifespan

R2E EC fans operate at V with W rated power. When replacing AC models, wire the 0-10V control signal alongside the standard three-phase power cable.

常见问题

Is the R2E225-RA92-20 suitable for high-reliability cooling?

It can be evaluated for demanding service using the documented ratings, installation limits and preventive-maintenance plan for the application.

How can noise be managed when using the R2E225-RA92-20?

Noise data is not listed in the supplied table. Use unobstructed airflow, secure mounting and suitable isolation where required.

How should buyers select the R2E225-RA92-20 for an operating point?

Match required airflow and pressure on the exact performance curve, then verify voltage, power, dimensions and environmental limits.

Does the R2E225-RA92-20 support speed control?

Control capability and input method must be confirmed in the exact-model datasheet and wiring diagram; do not infer them from the fan family alone.
