Product Features

Reliable Blower

The ebm-papst K3G280-AU11-C3 is an EC centrifugal blower for industrial cooling, providing directed airflow in enclosures and cooling assemblies.

Data includes 3`380-480 V operation for matching airflow to system resistance. The datasheet lists ball-bearing support, IP54 protection, PWM/0-10 V/MODBUS speed control for durable motor support. Installed noise depends on the duty point and airflow path. Correct electrical selection and clear inlet spacing support efficient cooling, reliable operation and long fan life.

Suitable for OEM engineers, manufacturers and maintenance buyers, the K3G280-AU11-C3 should be checked for wiring, mounting, duty point and ambient limits before selection. Its documented operating data supports model comparison, replacement planning and purchasing review.

Application Industry

Industrial Cooling

The K3G280-AU11-C3 ebm-papst fan is used in industrial equipment cooling where continuous heat generation requires controlled airflow for equipment heat removal and stable system operation.

AC to EC Replacement — K3G Compact EC Centrifugal

The ebm-papst K3G280-AU11-C3 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.
