AC version: Axial wall fan with square wall plate, in AC version. Brief description: Protective grille on the suction side, contact protection in accordance with DIN EN ISO 13857. 8-blade impellers made of glass fiber reinforced polyamide. Thermal overload protection as standard. Fans meet the requirements of the European Ecodesign Regulation (EC) No. 327/2011 Directive 2009/125/EC. Vibration-free operation thanks to dynamically balanced impeller and motor (shaft-rotor), in accordance with quality level 6.3, DIN ISO 1940, Part 1. High ventilation-side efficiency, low operating noise. Increased longevity thanks to high-quality materials such as low-noise ball bearings. Fans are maintenance-free. Reversible operation of the fans possible. Customer-specific special voltages available as special versions on request and for an additional charge. Installation for ventilation and exhaust ventilation possible in any position. Direction of flow: The direction of flow is marked. Standard exhaust air operation, direction of flow through motor suction. AC motor: Asynchronous motor. Not suitable for conveying water vapor-saturated air. Rated voltage 230 V, 50 Hz. Fans ... B: Capacitor motors with operating capacitor on the protective grille or on the wall sleeve, protection class IP 55. Fans ... D: Capacitor motors with operating capacitor in the terminal box, protection class IP 54. Fans ... E: Shaded pole motors, protection class IP 54. Speed controllable. Exception for types EZQ 45/6 B and EZS 45/6 B. Devices can be continuously controlled with an optional speed controller or they can be switched in stages with an optional 5-stage transformer. Reversible. Exception for fans with shaded pole motor (... E). Reversing operation: The volume flow is reduced by approx. 35% in the event of an abnormal direction of flow. Thermal overload protection as standard. Electrical connection: On terminal block in the end cover of the motor. Safety instructions: The fan may only be operated if the impeller is protected against contact in accordance with DIN EN ISO 13857, e.g. with Maico protective grille SG.
