Maico 0087.0209 EZD 40/4 B axial roof fan

Brief description: Housing, base plate, inlet nozzle and rain protection hood made of galvanized sheet steel. Galvanized protective grille on the outlet side, contact protection in accordance with DIN EN ISO 13857. Stable transport eyes enable transport by crane. 8-blade impeller 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 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 available as special versions on request and for an additional charge. Can be switched to ventilation or exhaust ventilation with a separate switch (except EZD...E). Air flow direction: The air flow direction is marked. Standard exhaust air operation, air flow direction blowing over the motor. AC motor: Asynchronous motor. Rated voltage 230 V, 50 Hz. Fans ...B and ...D: Capacitor motors with operating capacitor in the terminal box. Fans ...E: Shaded pole motors. Protection class EZD...D and ...E IP 54. Protection class EZD...B IP 55. 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 motors (...E). Reverse operation: The volume flow is reduced by approx. 35% if the air flow direction is abnormal. Thermal overload protection as standard. Electrical connection: Connection cable, approx. 1.7 m long. Safety instructions: The fan may only be put into operation if the impeller is protected against contact in accordance with DIN EN ISO 13857, e.g. with a Maico protective grille SG. Correct permanent installation with a horizontal mounting position, permanently laid electrical supply line and correct air routing via a shaft or pipe is mandatory.
