AC version: Axial wall fan with square wall plate, AC version. Short description: Protective grille on the suction side, accidental contact protection in accordance with DIN EN ISO 13857. 8-blade impeller made of glass fiber reinforced polyamide. Standard thermal overload protection. Fans meet the requirements of the European Ecodesign Regulation (EC) No.327/2011 Directive 2009/125/EC. Vibration-free operation by dynamically balanced impeller and motor (shaft-rotor), according to quality level 6.3, DIN ISO 1940, part 1. High ventilation efficiency, low operating noise. Increased long-life by high-quality materials such as low-noise ball-bearings. Fans are maintenance-free. Reversible operation of the fans is possible. Custom special voltages available as special versions on request and at extra cost. Installation for ventilation in every position possible Direction of conveyance: The direction of conveyance is marked. Standard exhaust operation, suction direction via motor. AC motor: Asynchronous motor. Not suitable for pumping water-vapor-saturated air. Rated voltage 230 V, 50 Hz. Fans ... B: Capacitor motors with operating capacitor on the protective grille or wall sleeve, protection class IP 55. Fans ... D: Capacitor motors with operating capacitor in connection box, protection class IP 54. Fans ... E: Split pole motor, protection class IP 54. Variable speed control Exception for type EZQ 45/6 B and EZS 45/6 B. Devices can be regulated continuously with optional speed controller or they can be switched in stages with an optional 5-stage transformer. Reversible. Exception for fans with split pole motor (... E). Reverse mode: The volume flow is reduced by approx. 35% with abnormal direction of delivery. Standard thermal overload protection. Electrical connection: On the terminal strip in the end cover of the motor. Safety instructions: The fan may only be put into operation if the contact protection of the impeller in accordance with DIN EN ISO 13857 is ensured, e.g. with MAICO protective gear SG.Article: EZQ 25/2 B, design: Square wall plate, displacement volume: 2100 m3/h, displacement volume: 1470 m3/h / in opt.
