Maico 0083.0116 Axial wall fan DZQ 20/2 B

Three-phase version: Axial wall fan with square wall plate, in three-phase version. Brief description: Protective grille on the suction side, contact protection in accordance with DIN EN ISO 13857. 8-blade impellers 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 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 available as special versions on request and for an additional charge. Installation for ventilation and exhaust ventilation possible in any position. Direction of flow: The direction of flow is marked. Standard exhaust air operation, direction of flow via motor suction. Three-phase motor: Asynchronous motor. Not suitable for conveying air saturated with water vapor. Rated voltage 400 V, 50 Hz. Protection class IP 55. Exception for type DZQ ... D IP 54. Speed controllable. Exception for type DZQ 40/2 B and DZS 40/2 B. Devices can be switched in stages using an optional 5-stage transformer. Reversible. Reversing operation: The volume flow is reduced by approx. 35% if the direction of flow is abnormal. Thermal overload protection as standard. Exception for type DZQ/DZS 25/4 D and pole-changing axial wall fans available on request. The connections are potential-free on terminals and must be connected to a motor protection switch, e.g. MV 25, or the control circuit of a contactor. Pole-changing fans: Ensure overload protection with a motor protection switch to be provided by the customer. Pole-changing motors with speed ratios of 8/4 or 4/2 are connected using the Dahlander principle. Electrical connection: On the terminal block in the end cover of the motor. 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.
