R3G630-AB07-01: The Giant of EC Ventilation
The R3G630-AB07-01 is one of the largest and most powerful EC centrifugal fans in the ebm-papst lineup. With a 630mm diameter, this unit is designed for critical infrastructure cooling, such as hyperscale data centers and large industrial process ventilation. The «RadiPac» aluminum impeller is designed for high efficiency at medium pressures. The 3-phase EC motor provides exceptional torque and speed stability, allowing the fan to maintain precise airflow setpoints regardless of filter loading. It is the preferred choice for constructing FanGrids (Fan Walls), where multiple units operate in parallel to provide redundancy (N+1) and huge airflow capacity.
Advanced Technical Data
- Diameter: 630 mm.
- Voltage: 3~ 380-480 VAC (50/60 Hz).
- Motor Power: Approx. 3.4 kW.
- Communication: RS485 Modbus-RTU.
- Protection: Integrated Locked-rotor, Over-temp, Phase-loss.
- EMC: Integrated filter for industrial environments (Class A).
Engineer’s Integration Guide
Lifecycle State: Active. Diagnosis: The most advanced feature is the internal logging. Via Modbus, engineers can retrieve the fan’s history (run hours, peak temps). If a unit in a FanGrid fails, the BMS can command the remaining fans to speed up instantly to compensate, maintaining the cooling load. Installation Advice: Ensure the inlet ring clearance is perfect (factory supplied nozzle recommended). For FanWalls, install backdraft dampers to prevent air recirculation through a failed fan. Compatibility: Fully supported by TIA Portal libraries. The R3G630 supports daisy-chaining, simplifying wiring significantly compared to traditional VFD setups where each motor needs a shielded cable run back to the panel.

Pro-Tip for FanGrids
Using the R3G630 in a 2×2 or 3×3 array is often more efficient and reliable than using one gigantic AC fan. It provides redundancy and easier handling during replacement.
