The ebm-papst K3G450-PA31-34 is an EC centrifugal blower for hvac systems, 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, IP55 protection, 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 K3G450-PA31-34 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.
The ebm-papst K3G450-PA31-34 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.
