R2E225-RA92-37 ebmpapst 230VAC 225mm AC Centrifugal Fan

Description

The ebmpapst R2E225-RA92-37 is a high-performance 230VAC single-phase AC centrifugal fan with an impeller size of Ø 225 mm and external dimensions of 225 x 225 x 100 mm, specifically engineered for intensive thermal management in commercial HVAC and industrial ventilation systems. Powered by a robust M2E068-DF motor, this single-intake backward-curved RadiCal motorized impeller delivers high-volume airflow and pressure performance. Operating at a rated speed of 2,500 / 2,600 RPM under 230 VAC (50 / 60 Hz), it efficiently draws 0.68 / 0.92 A with a power consumption of 155 / 210 W and a starting current of 1.25 / 1.2 A. Built with a 7-blade PA plastic impeller, painted black rotor surface, IP44 protection rating, Insulation Class F, and precision ball bearings, it operates with a 3.5 µF / 450 VDB capacitor and weighs 2.3 kg. The R2E225-RA92-37 ensures long-term continuous-duty reliability under operating temperatures ranging from -25 to +70 °C.
