Axial tube fan DZR 30 / 4 B Ex t rotary current, ex- protected, 1,760 m3 / h

Product design: For application temperatures of -20 ° C < = Ta < = + 60 ° C. Special features: Axial tube fan, explosion-proof, medium dust. Explosion protection and approvals according to ATEX and IECEx. Ex II 2 D Ex tb IIIB T135 ° C / T200 ° C Db IP64 X / Ex II 2 D Ex h IIIB T135 ° C / T200 ° C Db X. Application temperatures depending on temperature class: T135 ° C -20 ° C < = Ta < = + 40 ° C, T200 ° C -20 ° C < = Ta < = + 60 ° C For all dusts of the Ex- group IIIA and IIIB qualified. MAICO Ex- fans meet the safety requirements of European Directive RL 2014 / 34 / EU for equipment and protection systems in potentially explosive areas. For zone 21 and 22. Protection type IP 64. Switchable for ventilation or ventilation. Tube case made of galvanized steel sheet, both sides with flange - hole image according to DIN 24155, for simple and direct installation into a pipe system. Installation possible in any location. 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. 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: DZR 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: clamping box mounted on the fan, ex- protected, with cable connection. Safety instructions: Ventilator in the case of free intake or inflation only in operation if the contact protection of the wing wheel is guaranteed in accordance with DIN EN ISO 13857, e.g. with protection grid SG.Article: DZR 30 / 4 B Ex t, conveyor volume: 1760 m3 / h, speed control: yes, reversible: yes, voltage: current, measurement voltage: 400 V, nominal power: 95 W, INenn: 0.48 A, I2b, temperature control: 440 ° C, weight: 440 ° C, weight: 440 ° C, weight: 440 ° C, weight: 440 ° C, weight: 440 ° C, weight: 440 ° C, weight: 440 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 ° C, weight: 460 °
