AC version: Axial wall fan with square wall plate, in AC version. Brief description: Guard grille on the suction side, contact hazard protection to DIN EN ISO 13857. 8-bladed impellers made of glass-fibre 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 due to dynamically balanced impeller and motor (shaft-rotor), according to quality class 6.3, DIN ISO 1940, part 1. High efficiency on the ventilation side, low operating noise. Increased durability due to high-quality materials such as low-noise ball bearings. Fans are maintenance-free. Reversible operation of the fans possible. Customised special voltages as special designs available on request and at extra cost. Installation for aeration and deaeration possible in any position. Direction of air flow: The direction of air flow is marked. Standard exhaust air operation, conveying direction via motor suction. AC motor: Asynchronous motor. Not suitable for conveying water vapour-saturated air. Rated voltage 230 V, 50 Hz. Fans ... B: Capacitor motors with operating capacitor on the guard 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 type EZQ 45/6 B and EZS 45/6 B. Units can be controlled steplessly with optional speed controller or switched in steps with optional 5-step transformer. Reversible. Exception for fans with shaded-pole motor (... E). Reversible operation: The volumetric flow is reduced by approx. 35 % in the event of an abnormal direction of flow. Thermal overload protection as standard. Electrical connection: To terminal strip in the end cover of the motor. Safety instructions: The fan may only be put into operation if protection against contact with the impeller is ensured in accordance with DIN EN ISO 13857, e.g. with Maico guard grille SG.Article: EZQ 25/2 B, Design: square wall plate, Delivery volume: 2100 m3/h, Delivery volumeNominal: 1470 m3/h / in opt. efficiency, Pressure pfs, Nominal: 135 Pa - in opt. efficiency, Speed nNominal: 2770 1/min - in opt. efficiency, Speed: 2833 1/min - in opt. efficiency.
