Description
The ebm-papst A2E300-AC47-01 (also known as A2E300AC4701) is an industrial-grade 300 mm (11.81 in) AC axial fan driven by an external rotor M2E068-EC motor. Engineered with five straight sheet-steel blades in a ‘V’ airflow configuration, this unit delivers high-volume throughput up to 1,590 CFM (2,700 m³/h) at 2,900 RPM on 60 Hz and 1,435 CFM (2,435 m³/h) at 2,650 RPM on 50 Hz. Rugged mechanical construction features dual maintenance-free ball bearings, an IP44 protection rating, H0+ environmental moisture protection, and an internally connected thermal overload protector (TOP). Electrical connection is facilitated via a 4-conductor PVC lead wire assembly configured for 230 VAC single-phase permanent split capacitor operation.
Key Features
- Heavy-Duty Aerodynamic Impeller: Five straight sheet-steel blades coated in black paint deliver robust mechanical strength and vibration-free air movement.
- External Rotor Motor: Integrated M2E068-EC single-phase motor provides efficient thermal dissipation and high operational torque across continuous S1 duty cycles.
- Integrated Motor Protection: Built-in internal thermal overload protector guards against phase loss, excessive ambient heat, and locked-rotor conditions.
- Industrial Ingress Sealing: Rated IP44 with H0+ environmental moisture classification and dedicated rotor-side condensation drainage holes for demanding environments.
- Flexible Installation: Engineered for horizontal or vertical rotor-up mounting with standardized 4xM4 mounting threads on a 58 mm pitch circle.

Applications
The ebm-papst A2E300-AC47-01 axial fan is primarily engineered for condenser coils, air-cooled chillers, and commercial refrigeration condensing units requiring high air volume displacement. It functions reliably within industrial heat pump assemblies, evaporative coolers, and ducted ventilation air intake cowls. Maintenance technicians and plant engineers also source this assembly for heat exchanger exhaust venting and cooling air circulation in heavy machinery compartments.
