AC version: Axial wall fan for flush-mounted installation, in AC version. Brief description: For flush-mounted installation. Installation possible in any position. Wall sleeve made of galvanized sheet steel. 8-blade impellers made of glass fiber reinforced polyamide. Plastic protective grille on the suction side, pearl white, contact protection in accordance with DIN EN ISO 13857. Thermal overload protection as standard. 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 efficiency on the ventilation side, 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 are available as special versions on request and for an additional charge. Air flow direction: The air flow direction is marked. Standard exhaust air operation, air flow direction suction via motor. AC motor: Asynchronous motor. Rated voltage 230 V, 50 Hz. Protection class IP 54. Exception EZF ... D, EZF ... E IP 54. 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, not reversible. Thermal overload protection as standard. Speed controllable. 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% if the conveying direction is abnormal. Not suitable for conveying air saturated with water vapor. Electrical connection: On terminal block in the end cover of the motor. Safety instructions: With free intake, the fan may only be operated if the impeller is protected against contact in accordance with DIN EN ISO 13857.
