Guards on the intake side, yellow chromate, touch protection according to DIN EN ISO 13857. 8-blade impeller made of glass fiber reinforced polyamide. Dynamically weighted in 2 levels, according to quality level 6.3, DIN ISO 1940, part 1. Installation possible in every position. Direction of conveyance: The following figure shows the direction of delivery: Direction A: Suction via the motor, standard. Conveyor direction B: Blowing over the engine, on request. Direction of rotation, reverse operation: The volume flow is reduced by approx. 35% with abnormal direction of delivery. Motor: Asynchronous motor. Variable speed control Exception: Type EZQ 45/6 B, EZS 45/6 B, DZQ 40/2 B and DZS 40/2 B. reversible. Exception: Fans with gap pole motor (...-E). Not suitable for pumping water-vapor-saturated air. Three-phase motor: Type series DZQ and DZS. Rated voltage 400 V, 50 Hz. IP 55 protection Exception DZQ/DZS... D IP 54 Standard thermal overload protection. Exception: Available on request at DZQ/DZS 25/4 D and polarity switchable axial wall fans. The connections are floating on terminals and must be connected to a motor circuit breaker, e.g. MV 25 or the control circuit of a contactor. Fan switches between terminals: Overload protection is ensured by the customer side with a motor circuit breaker. Pole-changing motors with a speed ratio of 8/4 or 4/2 are switched in the Dahlander principle. Electrical connection: On the terminal strip in the end cover of the motor. Safety instructions: The fan may only be put into operation if the contact protection of the impeller is ensured in accordance with DIN EN ISO 13857.Article: DZQ 40/42 B, design: Square wall plate, displacement volume: 4490 m3/h / 8960 m3/h, displacement volume: 3270 m3/h / 6700 m3/h / in opt.
