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: EZQ 20 / 4 E, version: square wall plate, conveyor volume: 475 m3 / h, speed: 1380 1 / min, wheel type: axial, speed control: yes, reversability: no, voltage: alternating current, measuring voltage: 230 V, net frequency: 50 Hz, nominal power: 35 W, inlet: 25 ° C, height: 445 ° C, height: 445 ° C, height: 445 ° C, height: 445 ° C, height: 445 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C, height: 455 ° C
