Product Insights

AC to EC Replacement — K3G Compact EC Centrifugal

The ebm-papst K3G280-AU11-C2 from the Compact 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

K3G 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.
