AC to EC Replacement — R3G RadiPac EC Centrifugal

The ebm-papst R3G190-RD45-03 from the RadiPac EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including R4D, R2D. 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

R3G 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.

Frequently Asked Questions

What is the representative feature of the R3G190-RD45-03?

The supplied comparison identifies a documented speed of 4,120 rpm; review it together with the other listed ratings rather than as a standalone selection criterion.

What distinguishes the R3G190-RD45-03 from a general-purpose fan?

Its EC backward-curved centrifugal fan configuration and a documented speed of 4,120 rpm provide model-specific criteria for matching Air Purification systems.

Does the R3G190-RD45-03 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.

How should the R3G190-RD45-03 be checked for compatibility?

Compare 190 mm, 200-277V, 169 W plus mounting, connector and duty-point requirements.
