Pipe sleeve made of galvanized sheet steel, with flange on both sides. 8-blade impellers made of glass fiber reinforced polyamide. Dynamically balanced in 2 planes, in accordance with quality level 6.3, DIN ISO 1940, Part 1. 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. High protection class IP 55. Exception EZR/DZR... D IP 54. Installation possible in any position. Motor: asynchronous motor, speed controllable. Exception: type DZR 40/2 B. Not suitable for conveying air saturated with water vapor. The conveying direction is marked on the device with a direction of rotation and conveying direction arrow. Reversing operation: The volume flow is reduced by approx. 35% if the conveying direction is abnormal. Three-phase motor: DZR series. Rated voltage 400 V, 50 Hz. Thermal overload protection as standard. Exception: Available on request for DZR 25/4 D and pole-changing axial tube fans. 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 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.
