The ebm-papst S4D450-AO14-01 is an AC axial fan for refrigeration cooling, providing directed airflow in enclosures and cooling assemblies.
Data includes 400 V operation, airflow up to 8330 m³/h and pressure up to 160 Pa for matching airflow to system resistance. The datasheet lists ball-bearing support, engineered-plastic impeller for durable motor support. Listed noise is 56 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 S4D450-AO14-01 should be checked for wiring, mounting, duty point and ambient limits before selection.
It can be evaluated for demanding service using the documented ratings, installation limits and preventive-maintenance plan for the application.
The table lists 56 dB. Use unobstructed airflow, secure mounting and suitable isolation where required.
The workbook marks the product RoHS Compliant. Obtain the exact-model declaration and any project-specific approvals required by the destination market.
