Description
The ebmpapst R2E250-AC09-05 is a high-performance 230VAC single-phase AC centrifugal fan with an impeller size of Ø 250 mm and external dimensions of 250 x 250 x 115 mm. Powered by a robust M2E068-GA motor, this single-intake backward-curved motorized impeller delivers high-volume airflow and pressure capabilities under free-air conditions. Operating at a rated speed of 2,650 RPM under 230 VAC (50 Hz), it draws a maximum current of 1.16 A with a power consumption of 265 W and a starting current of 1.0 A. Built with a 16-blade hot-dip galvanized sheet steel impeller, unpainted rotor surface, IP44 protection rating, Insulation Class B, and precision ball bearings, it operates with an 8 µF / 400 VDB capacitor (S2 standard) and weighs 3.9 kg, supporting reliable continuous-duty performance across operating temperatures from -25 to +30 °C.
