Product Features

Efficient EC Cooling

R3G355-FJ91-01 is an ebm-papst EC centrifugal fan for Data Center Cooling, 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, 1500 W input, 355 mm size, up to 7345 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. This approach helps OEMs reduce integration risk and plan dependable thermal performance.

Application Industry

Data Center Cooling

Used in data centers to remove heat from high-density computing equipment. This industrial cooling fan supports steady air circulation and reliable operation in continuous-duty facilities.

AC to EC Replacement — R3G RadiPac EC Centrifugal

The ebm-papst R3G355-FJ91-01 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.
