Basic Product Information External rotor motor with maintenance-free operation 230V AC, 50/60Hz dual-frequency operation IP44 protection rating for dust and splash resistance Thermal overload protection for enhanced safety Compact design with standardized mounting dimensions Low noise and high efficiency for energy savings Forward-curved centrifugal impeller for high airflow at low speeds Technical Specifications Version & Model Difference The R4E355-RM03-05 is a specific model within the R4E355 series. Compared to other variants, this model features a 230V AC motor with dual-frequency capability (50/60Hz) and a power rating of 0.65 kW. Some versions may have different voltage ratings (e.g., 115V AC) or higher power outputs. The RM03-05 designation indicates a particular motor and impeller configuration optimized for moderate airflow and pressure requirements. Always verify the exact model number for compatibility with your system. Application Scenarios Can this fan be used in outdoor applications? Yes, the IP44 protection rating makes it suitable for outdoor use where it is protected from direct water jets. However, it should be shielded from heavy rain or prolonged exposure to moisture to ensure longevity. Is the R4E355-RM03-05 compatible with variable speed drives? The fan is designed for direct mains operation. For speed control, it can be used with phase-cut (triac) controllers or variable transformers. It is not compatible with standard VFDs unless specified by ebm-papst, as the motor is not inverter-rated. What maintenance is required for this fan? The external rotor motor is maintenance-free. Periodic cleaning of the impeller and housing is recommended to prevent dust buildup, which can affect performance. Bearings are sealed and do not require lubrication. What is the airflow capacity of the ebm-papst R4E355-RM03-05? The fan delivers up to 2200 m³/h at free blowing conditions, but actual airflow depends on system resistance. At typical operating points, it can achieve around 1800 m³/h at 150 Pa static pressure. ebm-papst W2E200-HK38-01 230 V AC Axial Fan ebm-papst A4E500AE0301 500 mm Axial Fan ebm-papst W2E200-HK38 Axial Fan ebm-papst R3G250-RE07-20 EC Centrifugal Fan ebm-papst D4E225-CC01-39 Centrifugal Fan (D4E225-CC01-39)
