The ebm-papst K3G560-PB31-71 is an EC centrifugal blower for hvac systems, providing directed airflow in enclosures and cooling assemblies.
Data includes 3`380-480 V operation, airflow up to 18290 m³/h and pressure up to 900 Pa 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. Listed noise is 76 dB at the stated test point. 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 K3G560-PB31-71 should be checked for wiring, mounting, duty point and ambient limits before selection.
The ebm-papst K3G560-PB31-71 from the Compact EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including R4D, R2D. Key benefits:
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.
