Maico 0086.0000 Axial duct fan EZR 20/2 B

AC version: Axial tube fan, AC version. Brief description: Tube sleeve made of galvanized sheet steel, with flange on both sides. 8-blade impellers made of glass fiber reinforced polyamide. Flange holes in accordance with DIN EN 12220:1998. DZR 56/6 B and DZR 56/4 B: Flange holes in accordance with DIN EN 12220: 1998. To avoid vibration transmission to the pipe system: Use elastic connecting pieces, feet and vibration dampers. 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 durability 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. Installation in any position possible. Direction of conveyance: The direction of conveyance is marked. Standard exhaust air operation, direction of conveyance sucking via motor. AC motor: Asynchronous motor. Not suitable for conveying air saturated with water vapor. Rated voltage 230 V, 50 Hz. High protection class IP 55. Exception EZR/DZR ... D IP 54. 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. Reversing operation: The volume flow is reduced by approx. 35% if the conveying direction is abnormal. Capacitor motor with operating capacitor ready for connection in the terminal box. Thermal overload protection as standard. The connections are potential-free on terminals and must be connected to a motor protection switch, e.g. MVE 10 (not suitable for EZR 25/4 D, EZR 30/6 B and EZR 35/6 B) or the control circuit of a contactor. Electrical connection: External terminal box with cable grommets. 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.
