产品特点

Reliable Blower

The ebm-papst K3G250-RR03-H4 is an EC centrifugal blower for motor cooling, providing directed airflow in enclosures and cooling assemblies.

Data includes 1~ 200-277 V operation and airflow up to 705 m³/h for matching airflow to system resistance. The datasheet lists ball-bearing support, IP55 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 K3G250-RR03-H4 should be checked for wiring, mounting, duty point and ambient limits before selection.

应用行业

Motor Cooling

The K3G250-RR03-H4 ebm-papst fan is used in industrial motor systems to remove accumulated heat around the motor body, supporting stable duty cycles and reducing thermal stress on nearby components.

AC to EC Replacement — K3G Compact EC Centrifugal

The ebm-papst K3G250-RR03-H4 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.
