ebm-papst R2E250-AQ05-12 – 230 V AC Centrifugal Fan (Motorized Impeller), 250 mm
The ebm-papst R2E250-AQ05-12 is a 230 V AC centrifugal fan from the ebm-papst R2E250 series, supplied as a single-intake motorized impeller. Its 250 mm backward-curved impeller has 11 blades in glass-fibre reinforced PA plastic. It is driven by the ebm-papst M2E068-DF single-phase, 2-pole external rotor motor, which runs on ball bearings and has a black-painted rotor.
At 230 V the fan runs at 2550 / 2750 rpm (50 / 60 Hz), draws 130 / 180 W and delivers up to 1230 / 1310 m³/h in free air. It still moves around 1000 m³/h against 100–120 Pa. Class F insulation, condensation drainage holes and an internally connected thermal overload protector (TOP) make it a robust choice for air handling, ventilation and cabinet cooling.
