Product Features

Efficient EC Cooling

R3G280-AU11-C1 is an ebm-papst EC centrifugal fan for New Energy, where controlled heat removal and airflow management must match the actual duty point. Its model-specific format supports OEM builds, retrofit planning and replacement sourcing.

Documented selection points include 3`380-480 V supply, 260 W input, 280 mm size, up to 5015 m3/h airflow. These values support electrical, envelope and duty-point comparison.

For procurement, verify voltage, duty point, dimensions, connector and mounting. Correct sizing and clear airflow paths support stable operation, controlled noise and long service life. Confirm speed control, IP protection and approvals in the exact-model datasheet. It supports applications that prioritize reliable operation and maintainable design.

Application Industry

Rail Transit

Used in rail-transport electronics and onboard equipment to remove internally generated heat. Reliable air circulation supports temperature control and stable operation in demanding transport environments.

AC to EC Replacement — R3G RadiPac EC Centrifugal

The ebm-papst R3G280-AU11-C1 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.
