The ebm-papst S2D250-BI02-01 is an AC axial fan for industrial cooling, providing directed airflow in enclosures and cooling assemblies.
Data includes 400 V operation and airflow up to 1950 m³/h 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 S2D250-BI02-01 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.
Its documented 400 V AC axial fan configuration provides a traceable match for projects whose electrical and airflow requirements align with the model data.
It is listed for Rail Transit Cooling. Confirm voltage, duty point, dimensions and mounting against the equipment requirements before selection.
Its AC axial fan configuration and 250 mm dimensions for installation planning provide model-specific criteria for matching Rail Transit Cooling systems.
Compare 250 mm, 400 V, 140 W plus mounting, connector and duty-point requirements.
