The ebm-papst S4D400-AP12-03 is an AC axial fan for refrigeration cooling, providing directed airflow in enclosures and cooling assemblies.
Data includes 400 V operation, airflow up to 4615 m³/h and pressure up to 120 Pa for matching airflow to system resistance. The datasheet lists ball-bearing support, IP44 protection 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 S4D400-AP12-03 should be checked for wiring, mounting, duty point and ambient limits before selection.
Correct sizing and operation within documented limits can reduce avoidable thermal stress and maintenance events; project savings require duty-cycle analysis.
Continuous operation must remain within the published electrical, thermal and aerodynamic limits; confirm the exact datasheet and system conditions.
Provide service access, keep the airflow path clean, inspect wiring and mounting, and investigate abnormal noise or vibration before continued use.
