Maico Ventilatoren Maico Roof fan 1900 m³/h 250 mm

Short description: Housing, base plate, current nozzle and rain-proof hood made of galvanized steel plate. Galvanized protective grille on the outlet side, accidental contact protection in accordance with DIN EN ISO 13857. Sturdy transport lugs enable crane transport. 8-blade impeller made of glass fiber reinforced polyamide. Standard thermal overload protection. Fans meet the requirements of the European Ecodesign Regulation (EC) No.327/2011 Directive 2009/125/EC. Vibration-free operation by dynamically balanced impeller and motor (shaft-rotor), according to quality level 6.3, DIN ISO 1940, part 1. High ventilation efficiency, low operating noise. Increased long-life by high-quality materials such as low-noise ball-bearings. Fans are maintenance-free. Reversible operation of the fans is possible. Custom special voltages available as special versions on request and at extra cost. Can be switched for ventilation with separate switch (exception: EZD ... E). Direction of conveyance: The direction of conveyance is marked. Standard exhaust air operation, delivery direction via motor blowing. AC motor: Asynchronous motor. Rated voltage 230 V, 50 Hz. Fans ... B and ... D: Capacitor motors with operating capacitor in connection box. Fans ... E: Gap pole motors. Protection class EZD... D and ... E IP 54 Protection class EZD... B IP 55 Variable speed control Devices can be regulated continuously with optional speed controller or they can be switched in stages with an optional 5-stage transformer. Reversible. Exception: For fans with split pole motor (... E). Reverse mode: The volume flow is reduced by approx. 35% with abnormal direction of delivery. Standard thermal overload protection. Electrical connection: Connection cable, approx. 1.7 m long. Safety instructions: The fan may only be operated if the contact protection of the impeller in accordance with DIN EN ISO 13857 is ensured, e.g. with MAICO protective grid SG. A professional fixed installation with horizontal installation position, permanently installed electrical supply line and correct air flow via shaft or pipe is prescribed.Article: EZD 25/2 B, displacement volume: 1900 m3/h, displacement volume: 1290 m3/h / in opt.
