Axial tube fan EZR 30 / 2 B DN300, AC

AC version: Axial pipe fan, in AC version. Short description: Tube case made of galvanized steel sheet, both sides with flange. 8-leaf wing wheels made of glass fibre-reinforced polyamide. Flange drilling according to DIN EN 12220: 1998. DZR 56 / 6 B and DZR 56 / 4 B: flange drilling according to DIN EN 12220: 1998. To avoid vibration transfer to the pipe system: use elastic connection pins, feet and vibration absorbers. 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. Installation possible in any location. Support direction: The support direction is marked. Standard exhaust air operation, direction of transport via engine suction. AC motor: type series EZR. Asynchronous motor. Not suitable for the production of steam-saturated air. Measurement voltage 230 V, 50 Hz. High protection type IP 55. Derogation EZR... D IP 54. Speed controllable. Devices can be controlled with optional speed control or can be switched with an optional 5-step transformer. Reversible. Reverse operation: The volume flow rate is reduced by about 35% with an abnormal direction of transport. Condenser engine with operating capacitor ready for connection in the terminal box. Thermal overload protection as standard. The connections are free of potential to clamps and must be connected to an engine full-length protection switch e.g. MVE 10-1 (not suitable for EZR 25 / 4 D, EZR 30 / 6 B and EZR 35 / 6 B) or the control circuit of a protective device. Electric connection: external terminal box with cable cases. 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, e.g. with Maico protection grid SG.Article: EZR 30 / 2 B, conveyor volume: 3690 m3 / h, conveyor volume: 2660 m3 / h / in the opt.
