Maico Ventilatoren 0086.0490 Axial fan 1100 m³/h 250 mm

Three-phase design: Axial pipe fan, three-phase. Short description: Tube sleeve made of galvanized steel, both sides with flange. 8-blade impeller made of glass fiber reinforced polyamide. Flange holes according to DIN EN 12220:1998. DZR 56/6 B and DZR 56/4 B: Flange holes according to DIN EN 12220: 1998. To avoid vibration transfer to the pipe system: Use elastic connecting joints, feet and vibration dampers. 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. Installation possible in every position. Direction of conveyance: The direction of conveyance is marked. Standard exhaust operation, suction direction via motor. Three-phase motor: Asynchronous motor. Not suitable for pumping water-vapor-saturated air. Rated voltage 400 V, 50 Hz. High protection class IP 55. Exception EZR/DZR ... D IP 54 Variable speed control Exception for type DZR 40/2 B. Devices can be switched in stages with an optional 5-phase transformer. Reversible. Reverse mode: The volume flow is reduced by approx. 35% with abnormal direction of delivery. Standard thermal overload protection. Exception available for type DZR 25/4 D and pole-reversible axial pipe fans on request. 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. Electrical connection: Outer-lying terminal box with cable sleeves. Safety instructions: The fan may only be put into operation if the contact protection of the impeller in accordance with DIN EN ISO 13857 is ensured, e.g. with MAICO protective gear SG.Article: DZR 25/4 D, displacement volume: 1100 m3/h, speed: 1425 1/min, wheel type: Axial, speed-controlled: Yes, Reversal ability: yes, type of voltage: three-phase, rated voltage: 400 V, mains frequency: 50 Hz, rated power: 50 W, Inside: 0.15 A, IMAX: 0.16 A, protection class: IP 54, heat class: B, pole switchable: no, Mains cable: 5 / 1.5 mm 2, mounting position: horizontal / vertical, material: steel sheet, galvanized, color: silver, weight: 5.74 kg, Weight with packing: 6.58 kg, nominal width: 250 mm, width: 304 mm, height: 372 mm, depth: 300 mm, Width with packaging: 420 mm, height with packaging: 430 mm, depth with packaging: 330 mm, medium temperature at rated current: -20 °C to 40 °C, medium temperature at IMAX: -20 °C to 40 °C, DC motor: false
