Product Features

Efficient EC Cooling

R3G400-AD23-33 is an ebm-papst EC centrifugal fan for HVAC and Ventilation, 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 48 V supply, 380 W input, 400 mm size, up to 4175 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. The listed ratings help buyers screen compatibility before final duty-point review.

Application Industry

HVAC Systems

Applied in HVAC and ventilation equipment to move and circulate air through the system. This industrial fan supports heat exchange, indoor-air management and reliable operation of climate-control equipment.

Product Insights

AC to EC Replacement — R3G RadiPac EC Centrifugal

The ebm-papst R3G400-AD23-33 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.
