The A4D450-AO14-02 from EBM-Papst is a robust AC axial fan measuring 446 × 446 × 214 mm. The fan is equipped with HyBlade technology and a three-phase AC motor, type M4D094-HA, providing high efficiency and low noise levels. It is an excellent choice for demanding industrial ventilation systems where reliable and efficient air treatment is required.
With support for both star and delta connections at 400/480 V AC and frequencies of 50/60 Hz, the fan is flexible and easy to integrate into existing systems. Its IP54 protection class makes it suitable for tougher environments, and the sickle-shaped HyBlade blades, made of pressed sheet metal coated with PP plastic, contribute to quiet and efficient operation.
