Industrial Inverter Cooling Blower
The RH35M-4EK.2F.1R is a centrifugal blower built for ABB ACS800 R8 drive cabinets. It delivers forced-air cooling for 300 W motor loads in heavy-industry environments such as cement, chemical and power plants. Maintenance teams specify this unit when original-equipment reliability is required for continuous ventilation duty.
Thermal and Electrical Profile
At 230 V the motor draws 1.4 A while spinning at 1340 rpm to move air through the inverter heatsink. The 350 mm blade diameter matches the OEM ductwork so airflow stays within design limits without extra pressure drop. Power consumption remains at the rated 300 W during normal operation.
Build and Integration
Germany Ziehl-Abegg construction uses custom ebm-papst tooling for exact fit in ACS800 R8 frames. The housing bolts directly to existing mounting points so replacement requires no fabrication. Blade geometry is tuned for the inverter’s airflow path, keeping dust ingress low in mining, marine and food-processing installations.

Questions about this item
How is the RH35M-4EK.2F.1R installed in an ACS800 R8 inverter and which step is commonly missed?
Mount the 350 mm blower in the designated R8 cooling duct, connect the 230 V supply to the 1.4 A terminals, and verify the 1340 rpm rotation direction before securing the cover — the direction check is the step most often skipped.
What maintenance or replacement will the RH35M-4EK.2F.1R need during its service life?
Plan periodic cleaning of the centrifugal impeller and inlet grille to prevent dust build-up that reduces airflow, and replace the unit if bearing noise appears or the 300 W motor can no longer maintain 1340 rpm under load.
What limit appears first when the RH35M-4EK.2F.1R runs continuously at full load?
The 300 W motor rating and 1.4 A current draw at 230 V define the thermal ceiling; sustained operation at 1340 rpm will hit winding temperature limits before airflow or mechanical limits are reached.
