The 4656EZU from EBM-Papst is a robust AC axial fan with a metal housing, measuring 119 × 120 × 38 mm. It is designed for demanding environments, delivering reliable airflow performance with a maximum free air flow of 124 m³/h at 50 Hz. With an IP65 rating, it withstands dust and water splashes without problems.
The fan is excellent for industrial machinery, cooling systems, and applications where the operating environment places high demands on durability and continuous operation. Thanks to ball bearings and impedance protection for locked rotor, it is built for long and maintenance-free operation.
