R2E190-AE77-B8 ebmpapst 230V 190mm AC Centrifugal Fan

Description

The ebmpapst R2E190-AE77-B8 is a high-performance 230VAC AC Centrifugal Fan featuring a backward-curved, single-intake impeller, designed as the definitive high-efficiency successor to the legacy R2E190-AO26-30 model, specifically engineered for mission-critical cooling in Industrial Frequency Converters and AHU systems. Driven by a 1-phase M2E068-BF external rotor motor with maintenance-free ball bearings, this 1.2 kg unit operates on a 230 VAC supply delivering a Max. Power Consumption of 58 / 75 W and a Max. Current Draw of 0.26 / 0.34 A at a rated speed of 2500 / 2700 RPM. This High-performance unit achieves a Max. Air Flow of 335.5 / 359.0 CFM (570.0 / 610.0 m³/h / 9.50 / 10.17 m³/min) and a Max. Static Pressure of 24.47 / 28.55 mmH₂O (240.0 / 280.0 Pa / 0.96 / 1.12 inAq). Featuring a thermal overload protector (TOP) and Class B insulation, this 7-blade unit is optimized for industrial VFD systems requiring seamless legacy replacement and robust airflow performance at the end.
