Description
The ebm-papst R2E225-BE47-09 (also known as R2E225BE4709) is an industrial unhoused backward-curved motorized centrifugal impeller powered by an integrated M2E068-EC single-phase external rotor motor, measuring 225 mm (8.86 in) in diameter by 88.00 mm (3.46 in) in depth. Operating at 230 VAC, 60 Hz, this high-performance fan delivers up to 755 CFM (1285 m³/h) of airflow at 3000 RPM with an electrical draw of 185 W and 0.81 A. Constructed with a 7-blade glass-fiber reinforced PA6 plastic impeller and heavy-duty dual ball bearings, it delivers reliable continuous S1 duty across demanding static pressure environments reaching up to 2.01 in H₂O (500 Pa). The unit is thermally protected by an internal thermal overload protector (TOP) and connects via a durable 4-conductor AWG20 PVC lead harness.
Key Features
- Aerodynamic Impeller Design: Glass-fiber reinforced PA6 composite backward-curved 7-blade wheel maximizes static pressure efficiency.
- Integrated External Rotor: Compact single-phase M2E068-EC motor saves space while delivering robust continuous torque.
- Internal Thermal Protection: Integrated thermal overload protector safeguards motor windings against overheating under severe loads.
- Universal Mounting Flexibility: Precision ball bearing architecture allows maintenance-free operation in any arbitrary spatial orientation.
- Robust Environmental Sealing: IP44 ingress protection rating resists dust ingress and water splashing in industrial environments.

Applications
The ebm-papst R2E225-BE47-09 backward-curved motorized impeller is engineered for high-static-pressure air movement across industrial ventilation, environmental control, and cleanroom infrastructure. It serves as a primary cooling and circulation blower inside data center precision air conditioning (CRAC/CRAH) units, semiconductor cleanroom fan filter units (FFUs), and commercial building heat recovery ventilation (HRV/ERV) plenums. Furthermore, it delivers reliable high-impedance thermal management in telecom power plant shelters, commercial refrigeration evaporators, and industrial enclosure heat exchangers.
