R4D450-FH03-01 is an ebm-papst AC centrifugal fan for Automation, where controlled heat removal and airflow management must match the actual duty point. Its model-specific format supports OEM builds, retrofit planning and replacement sourcing.
Documented selection points include 480 V supply, 1190 W input, 450 mm size, up to 9065 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. This approach helps OEMs reduce integration risk and plan dependable thermal performance.
Condenser Cooling: The R4D450-FH03-01 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.
Its documented 480 V AC backward-curved centrifugal fan configuration provides a traceable match for projects whose electrical and airflow requirements align with the model data.
The supplied table lists 9,065 m³/h, 550 Pa, 1,680 rpm; use the exact datasheet for the complete operating curve.
Verify mounting orientation, inlet and outlet clearance, fastener security, electrical connections and the exact dimensional drawing before startup.
