Axial wall fan EZS 25 / 4 D steel wall ring, AC, DN250

AC version: Axial wall fan with steel wall ring, in AC version. Short description: For cleaning. Safety belts on the suction side, contact protection according to DIN EN ISO 13857. 8-leaf wing wheels 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. Installation possible for ventilation and ventilation in any location. Support direction: The support direction is marked. Standard exhaust air operation, direction of transport via engine suction. AC motor: type series EZQ / EZS. Asynchronous motor. Not suitable for the production of steam-saturated air. Measurement voltage 230 V, 50 Hz. Ventilators... B: Condenser motors with operating capacitor on the protection grid or on the wall sleeve, protection type IP 55. Ventilators... D: capacitor motors with operating capacitor in the connection box, protection type IP 54. Ventilators... E: Fission motors, protection type IP 54. Speed controllable. The exception for type EZQ 45 / 6 B. Devices can be controlled continuously 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: on the terminal bar in the engine's final cover. 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.Article: EZS 25 / 4 D, version: steel wall ring, conveyor volume: 1000 m3 / h, speed: 1425 1 / min, wheel type: axial, speed control: yes, reversible: yes, voltage: AC-current, voltage: 230 V, power: 50 Hz, nominal power: 32 W, inline: 0.A to 60 ° C, weight: 400 ° C: 400 mm, height: 80 ° C, height: 80 ° C, diameter: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C, height: 80 ° C
