Wheel: Axial roller made from conductive plastic. Balancing quality of the engine-impeller combination G 6.3 according to category BV-3 according to ISO 14694. Direction of conveyance: The direction of conveyance is marked. Standard exhaust operation, suction direction via motor. Motor: Robust three-phase motor with ball bearing, maintenance-free. Reversible. Reverse mode: The volume flow is reduced by approx. 35% with abnormal direction of delivery. Operating mode S1 (continuous mode). Speed control with transformer TR... possible. Exception: DZR 35/2 B ex... The temperature in the fan motor is monitored by PTC thermistor. The PTC thermistors must be connected to a tripping system (safety device in accordance with Directive RL 2014/34/EU) which permanently disconnects the fan from the mains when the temperature is too high. The MAICO PTC thermistor tripping system MVS 6 or TMS is recommended as the activation system. Electrical connection: Terminal box mounted on fan, explosion-proof, with cable gland. Safety instructions: Do not operate the fan during free suction or blowing-out unless the contact protection of the impeller in accordance with DIN EN ISO 13857 is ensured, e.g. with protective grille SG.Article: DZR 20/2 B Ex e, displacement volume: 1050 m3/h, speed: 2950 1/min, impeller type: Axial, speed-controlled: Yes, Reversal ability: yes, type of voltage: three-phase, rated voltage: 400 V, mains frequency: 50 Hz, rated power: 65 W, cosphi: 0.4, inner: 0.23 A, Imax at Unn: 0.25 A, protection class: IP 64, heat class: F, mounting position: vertical / horizontal, material: steel plate, galvanized, material housing: steel plate, galvanized, Colour: galvanized, weight: 7.24 kg, weight with packing: 7.91 kg, nominal width: 200 mm, width: 317 mm, height: 317 mm, depth: 240 mm, Width with packaging: 350 <<19 mm, height with packaging: 335 mm, depth with packaging: 265 mm, EX designation according to ATEX directive: Ex II 2 G, EX designation according to standard: Ex EB IIB + H2 T4 GB / Ex h IIB + H2 T4 T4 GB, Ta ambient temperature: -20 °C = +40 °C, IA/IN: 100, time TA: 69 sec., operating mode: S1, PTC DIN 44082: M 7.3, EUSEPRI EX 1900Ex TEX.
