Product Features

High Static Airflow

The ebm-papst K2E225-RB92-09 is an AC centrifugal blower for drive cooling, inverter cooling, providing directed airflow in enclosures and cooling assemblies.

Data includes 230 V operation and pressure up to 890 Pa for matching airflow to system resistance. The datasheet lists ball-bearing support, engineered-plastic 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 K2E225-RB92-09 should be checked for wiring, mounting, duty point and ambient limits before selection.

Application Industry

Drive Cooling

The K2E225-RB92-09 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.

Inverter Cooling

The K2E225-RB92-09 ebm-papst fan is applied in inverter and drive equipment where concentrated electronic heat requires forced airflow to protect power components and maintain stable operation.

Product Insights

AC to EC Replacement — K2E EC Centrifugal

The ebm-papst K2E225-RB92-09 from the EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including K2D. 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

K2E 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.
