Maico 0086.0030 May DZR 40/4 B Axial duct fan, DZR 40/4 B

Three-phase version: Axial duct fan, in three-phase version. Brief description: Pipe 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 through high-quality materials such as low-noise ball bearings. Fans are maintenance-free. Can be installed in any position. Air flow direction: The air flow direction is marked. Standard exhaust air operation, air flow direction suction via motor. Three-phase motor: DZR series. Asynchronous motor. Not suitable for conveying water vapor-saturated air. Rated voltage 400 V, 50 Hz. High protection class IP 55. Exception DZR ... D IP 55. Speed controllable. Exception for type DZR 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 air flow 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 motor protection switch, e.g. MV 25-1, or the control circuit of a contactor. Pole-changing fans: Ensure overload protection with a 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 the impeller is protected against contact in accordance with DIN EN ISO 13857, e.g. with a Maico protective grille SG.
