The ebm-papst K3G630-FB32-03/F01 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 21540 m³/h and pressure up to 600 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 73 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 K3G630-FB32-03/F01 should be checked for wiring, mounting, duty point and ambient limits before selection.
Control capability and input method must be confirmed in the exact-model datasheet and wiring diagram; do not infer them from the fan family alone.
Check for blocked airflow paths, incorrect supply, loose wiring, abnormal rotation or system resistance before consulting the exact service documentation.
The workbook marks the product RoHS Compliant. Obtain the exact-model declaration and any project-specific approvals required by the destination market.
The supplied table lists 21,540 m³/h, 600 Pa, 1,420 rpm; use the exact datasheet for the complete operating curve.
