Axial roof fan EZD 50 / 6 B horizontal inflating, AC, DN500

Short description: housing, base plate, supply nozzle and rain protection hood made of galvanized steel sheet. Galvanized protection grid on the fading side, contact protection according to DIN EN ISO 13857. Stable transport eyes allow transport by crane. 8-leaf wing wheel made of glass fibre-reinforced polyamide. Thermal overload protection as standard. Ventilators meet the requirements of European ecodesign Regulation (EC) No 327 / 2011 Directive 2009 / 125 / EC. Vibration-free run by dynamically weighted wing wheel and engine (wave rotor), according to quality level 6.3, DIN ISO 1940, part 1. High ventilation-side efficiency, low operating noise. Increased durability through high-quality materials such as low-noise ball bearings. Fans are maintenance-free. Reversible operation of the fans possible. Customer-specific special voltages as special versions available on request and at an additional price. Can be switched over for ventilation or ventilation with a separate switch (except EZD... E). Support direction: The support direction is marked. Standard exhaust air operation, direction of transport over engine flashing. AC motor: Asynchronous motor. Measurement voltage 230 V, 50 Hz. Ventilators... B and... D: capacitor motors with operating capacitor in the connection box. Ventilators... Protection type EZD... D and... E IP 54. Protection type EZD... B IP 55. Speed controllable. Devices can be controlled with optional speed control or can be switched with an optional 5-step transformer. Reversible. Exemptions: for fans with a split-pole engine (... E). Reverse operation: The volume flow rate is reduced by about 35% with an abnormal direction of transport. Thermal overload protection as standard. Electric connection: connection cable, about 1.7 m long. Safety instructions: The fan may only be put into operation if the contact protection of the wheel is guaranteed in accordance with DIN EN ISO 13857, for example with Maico protection grid SG. A professional fixed installation at horizontal installation position, fixed electrical supply line and correct air flow via shaft or pipe is required.
