EZF 40 / 4 B, Axial wall-in fan EZF 40 / 4 B

Axial wall mounting fan EZF 40 / 4 B underplaster, AC, DN400

AC version: Axial wall installation fan for undercleaning installation, in AC version. Short description: To the underfloor assembly. Installation possible in any location. Wall sleeve made of galvanized steel sheet. 8-leaf wing wheels made of glass fibre-reinforced polyamide. Plastic protection belts on the suction side, pearl white, contact protection according to DIN EN ISO 13857. Thermal overload protection as standard. 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. Support direction: The support direction is marked. Standard exhaust air operation, direction of transport via engine suction. AC motor: type series EZF. Asynchronous motor. Measurement voltage 230 V, 50 Hz. Protection type IP 55. Derogation ECF... D, ECF... E IP 54. Ventilators... B: Condenser motors with operating capacitor on the protective grid or on the wall sleeve. Ventilators... D: capacitor motors with operating capacitor in the connection box. Ventilators... Thermal overload protection as standard. 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. Not suitable for the production of steam-saturated air. Electric connection: on the terminal bar in the engine's final cover. Safety instructions: In the case of free suction, the fan may only be put into operation if the contact protection of the wheel is guaranteed in accordance with DIN EN ISO 13857.
