SKU CH-HGNK-N6ETW MPN RH45M-VDK.4F.1RMotor

Centrifugal cooling fan with 450 mm blades, 350 W motor and 400 V supply

  • High airflow for industrial cooling with 450 mm blade diameter
  • Dual-speed operation at 1210 and 830 r/min for flexible performance
  • High power 350 W motor handles demanding thermal loads
  • 400 V three-phase supply suits industrial electrical infrastructure
  • Centrifugal design delivers focused pressure for ducted airflow applications

Industrial centrifugal fan

The RH45M-VDK.4F.1R is a ZIEHL-ABEGG centrifugal fan built for industrial cooling duties. Its 450 mm blade diameter and dual-speed motor suit equipment enclosures, rail vehicles and medical systems that need steady airflow. Custom processing is available for specialised integration. Buyers who need a compact axial fan for a desktop PC cannot use this unit.

Thermals noise and power

The motor runs at 350 W or 690 W depending on winding, drawing 0.66 A or 1.3 A at 400 V. Two fixed speeds of 830 r/min and 1210 r/min let the installer choose the airflow level that matches the thermal load. No variable-speed control or acoustic data are supplied.

Accessories and software

The package contains only the fan assembly; no mounting brackets, wiring harnesses or control software are included. Integration requires separate procurement of hardware and any drive electronics the application demands.

Questions about this item

How do I wire the RH45M-VDK.4F.1RMotor centrifugal fan for 400 V three-phase supply?

Connect the three-phase 400 V lines to the motor terminals following the wiring diagram on the nameplate; the critical step people miss is verifying the rotation direction matches the arrow on the housing before securing the impeller.

Which components of the RH45M-VDK.4F.1RMotor will need replacement after extended industrial use?

The motor bearings and impeller blades are the primary wear items; plan bearing replacement when vibration or noise increases beyond the baseline measured at 1210 r/min.

What thermal limit appears first when the RH45M-VDK.4F.1RMotor runs continuously at 350 W?

The motor winding insulation class defines the maximum continuous temperature; sustained operation at 350 W will reach that limit before the 1.3 A current rating is exceeded.
