Axial wall fan DZQ 45 / 4 B Ex e wall plate, rotary current, ex- protection, DN450

Product design: Rotary current motor, Ex II 2G Ex eb IIB + H2 T3 / T4 Gb X / Ex II 2G Ex h IIB + H2 T3 / T4 Gb X. For use temperatures of -20 ° C < = Ta < = + 40 ° C Switchable for ventilation or ventilation. Special features: Axial wall fan, explosion-proof, medium gas. Explosion protection and approvals according to ATEX and IECEx. For all gases and vapours of the Ex- group IIA and IIB qualified and additionally for hydrogen. MAICO Ex- fans meet the safety requirements of European Directive RL 2014 / 34 / EU for equipment and protection systems in potentially explosive areas. For zones 1 and 2, types of protection: e - increased safety and c - constructive safety. Protection type IP 64. Safety belts on the suction side, contact protection according to DIN EN ISO 13857. Installation possible in any location. Type series: EZQ / DZQ.. Ex e with square wall plate. EZS / DZS.. Ex e with steel wall ring. Wheel: Axial wheel made of conductive plastic. The weight quality of the engine wheel combination G 6,3 by category BV-3 according to ISO 14694. Support direction: The support direction is marked. Standard exhaust air operation, direction of transport via engine suction. Rotary current motor: Robust current motor with ball bearing, maintenance-free. Reversible. Reverse operation: The volume flow rate is reduced by about 35% with an abnormal direction of transport. Type of operation S1 (continuous operation). Speed control with transformer TR... possible. Exemptions: DZ.. 35 / 2 B Ex... The temperature in the fan engine is monitored by cold conductor. The cold conductors must be connected to a discharge system (safety device in accordance with Directive RL 2014 / 34 / EU) which permanently separates the fan from the net at too high temperatures. The MVS 6 or TMS MAICO- cold-pressure trigger system is recommended as a trigger system. Electric connection: EZ.. Ex..: connection line about 0.5 m long. DZ.. Ex..: Connection line about 1.7 m long. Other terminal box, ex- protected, with cable connection.
