Fan - Duct fan 1100m³/h DZR 20/2 B

Fan - Duct fan 1100m³/h DZR 20/2 B – Maico – 0086.0020 – 4012799860204: Fan DZR 20/2 B, housing material=stainless steel, air volume unloaded=1100 m³/h, connection voltage=400 V, DC motor=no, protection class (IP)=IP55, pole-changing=no, length=240 mm, diameter of the housing =254 mm, three-phase version: Axial tube fan, in three-phase version. Short description: Pipe sleeve made of galvanized sheet steel, with flange on both sides. 8-blade impellers made of glass fiber reinforced polyamide. Flange holes according to DIN EN 12220:1998. DZR 56/6 B and DZR 56/4 B: Flange holes according to 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 running thanks to dynamically balanced impeller and motor (shaft-rotor), in accordance with quality level 6.3, DIN ISO 1940, Part 1. High ventilation 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 are available as special versions on request and at an additional cost. Installation possible in any position. Conveying direction: The conveying direction is marked. Standard exhaust air operation, conveying direction via motor suction. Three-phase motor: asynchronous motor. Not suitable for pumping air saturated with water vapor. Rated voltage 400 V, 50 Hz. High protection class IP 55. Exception EZR/DZR ... D IP 54. Speed controllable. Exception for type DZR 40/2 B. Devices can be switched step by step using an optional 5-stage transformer. Reversible. Reversing operation: The volume flow decreases by approx. 35% if the conveying direction is abnormal. Thermal overload protection as standard. Exception for type DZR 25/4 D and pole-changing axial tube fans available on request. The connections are potential-free on terminals and must be connected to a full motor protection switch, e.g. MV 25, or the control circuit of a contactor. Pole-changing fans: Ensure overload protection with a full motor protection switch to be provided on site. Electrical connection: External terminal box with cable grommets. Safety instructions: The fan may only be put into operation if contact protection of the impeller is guaranteed in accordance with DIN EN ISO 13857, e.g. with Maico protective grille SG.
