Axial wall fan AC, explosion protection, DN200 - Ex-proof ventilator EZQ 20/4E E Ex e – Maico – 0083.0850 – 4012799838500: Axial wall fan AC, explosion protection, DN200 EZQ 20/4E E Ex e nominal voltage 230... 230V, frequency 50... 50Hz, power consumption 45kW, housing material steel, unloaded air volume 440m³/h, protection class (IP) IP64, duct width 345mm, channel height 345mm, installation location wall, for Ex zone gas 1, 2, for Ex zone dust without, device group according to Directive 94/9/EC II, explosion protection category for gas ATEX gas explosion protection, cat. 2G, Temperature class according to Directive 94/9/EC T1 to T3, protective grille on the suction side, yellow chromated, contact protection according to DIN EN ISO 13857. 8-bladed impellers made of glass fiber reinforced polyamide. Dynamically balanced in 2 levels, in accordance with quality level 6.3, DIN ISO 1940, Part 1. Installation possible in any position. Conveying direction: The following figure shows the conveying direction: Conveying direction A: Suction via the motor, standard. Conveying direction B: Blowing via the motor, on request. Direction of rotation, reversing operation: The volume flow decreases by approx. 35% if the conveying direction is abnormal. Motor: asynchronous motor. Speed controllable. Exception: Type EZQ 45/6 B, EZS 45/6 B, DZQ 40/2 B and DZS 40/2 B. Reversible. Exception: Fans with shaded-pole motors (...-E). Not suitable for pumping air saturated with water vapor. Three-phase motor: DZQ and DZS series. Rated voltage 400 V, 50 Hz. Protection class IP 55. Exception DZQ/DZS... D IP 54. Thermal overload protection as standard. Exception: Available on request for DZQ/DZS 25/4 D and pole-changing axial wall fans. 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. Pole-changing motors with speed ratios of 8/4 or 4/2 are connected using the Dahlander principle. Electrical connection: To the terminal strip in the end cover of the motor. 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.
