Product Features

High Static Airflow

The ebm-papst D2E146-AP47-C3 is an AC centrifugal blower for drive cooling, providing directed airflow in enclosures and cooling assemblies.

Data includes 230 V operation, airflow up to 700 m³/h and pressure up to 625 Pa for matching airflow to system resistance. The datasheet lists ball-bearing support, steel impeller 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 D2E146-AP47-C3 should be checked for wiring, mounting, duty point and ambient limits before selection.

Application Industry

Drive Cooling

The D2E146-AP47-C3 ebm-papst fan is applied in variable-frequency drives and power-electronic cabinets, where continuous airflow helps control internal temperature and supports dependable equipment operation.

Product Insights

AC to EC Replacement — D2E EC Axial

The ebm-papst D2E146-AP47-C3 from the EC Axial series is a direct energy-saving replacement for legacy AC fans including D2D, A2D. 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

D2E 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.
