The ebm-papst R4D450-AD12-06 is an AC centrifugal fan for Automation, combining application-focused airflow with practical integration criteria. It serves equipment manufacturers and maintenance teams that require traceable model selection.
Documented selection points include 400 V supply, 650 W input, 450 mm size, up to 4655 m3/h airflow. These values support electrical, envelope and duty-point comparison.
For procurement, verify voltage, duty point, dimensions, connector and mounting. Correct sizing and clear airflow paths support stable operation, controlled noise and long service life. Confirm speed control, IP protection and approvals in the exact-model datasheet. It supports applications that prioritize reliable operation and maintainable design.
Condenser Cooling: The R4D450-AD12-06 axial fan excels at condenser heat rejection in refrigeration and HVAC.
AHU Air Handling: Engineered for integration into Air Handling Units.
Industrial Process Ventilation: Machinery cooling, enclosure ventilation and process air movement. Hengrui provides custom engineering support.
It is listed for Automation. Confirm voltage, duty point, dimensions and mounting against the equipment requirements before selection.
Compare 450 mm, 400 V, 650 W plus mounting, connector and duty-point requirements.
Continuous operation must remain within the published electrical, thermal and aerodynamic limits; confirm the exact datasheet and system conditions.
The supplied comparison identifies a listed airflow of 4,655 m³/h; review it together with the other listed ratings rather than as a standalone selection criterion.
