Product Insights

AC to EC Replacement — R2E EC Centrifugal

The ebm-papst R2E225-RA92-34 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.
