ebm-papst R2E225-AT51-05 – 230 V AC Centrifugal Fan (Motorized Impeller), 225 mm
The ebm-papst R2E225-AT51-05 is a 230 V AC centrifugal fan from the ebm-papst R2E225 series, supplied as a single-inlet motorized impeller. Its 225 mm backward-curved impeller has 11 blades in glass-fibre reinforced PA6 plastic. It is driven by the ebm-papst M2E068-DF single-phase, 2-pole external rotor motor on ball bearings, with a black-painted rotor.
At 230 V the fan runs at 2650 / 2950 rpm (50 / 60 Hz) and draws 105 / 145 W. It delivers up to approx. 825 m³/h at 50 Hz. The motor is protected by an internal thermal overload protector (TOP). With H1 moisture protection and condensation drainage holes, the fan copes well with humid conditions, which makes it a robust choice for air handling, ventilation and cabinet cooling.
