R2E270-AA01-05 ebmpapst 230V 270mm AC Centrifugal Fan

Description

The ebmpapst R2E270-AA01-05 is a high-performance 230VAC AC Centrifugal Fan featuring a backward-curved, single-inlet impeller, specifically engineered for mission-critical cooling in Industrial Frequency Converters and ventilation systems. Driven by a 1-phase M2E074-GA external rotor motor with maintenance-free ball bearings, this 4.7 kg unit operates at 230 VAC delivering a Max. Power Consumption of 280 / 430 W and a Max. Current Draw of 1.23 / 1.88 A at a rated speed of 2750 / 3100 RPM. This High-performance unit achieves a Max. Air Flow of 903.5 / 1000.6 CFM (1535.0 / 1700.0 m³/h / 25.58 / 28.33 m³/min) and a Max. Static Pressure of 50.99 / 61.18 mmH₂O (500.0 / 600.0 Pa / 2.01 / 2.41 inAq). Featuring a thermal overload protector (TOP) and Class F insulation, this 11-blade unit with sheet steel construction is optimized for industrial VFD systems requiring steady airflow and high static pressure in any installation position at the end.
