VENTILATOR FANS VNC

One-sided suction ventilator fans of the VNC type are of a radial-flow low-pressure design with directly installed electric motors. These ventilator fans are manufactured for a non-explosive environment. The ventilator fan is of circulating type with isolating plate and is not provided with a spiral casing. The ventilator fan is intended for circulation of air with temperature ranges of up to 250°C.

One-sided suction ventilator fans of the VNC type are of a radial-flow low-pressure design with directly installed electric motors. These ventilator fans are manufactured for a non-explosive environment. The ventilator fans are powered with flange electric motors where the fan propeller is set overhung on the shaft of the electric motor. The ventilator fan is welded from steel plates and it has zinc surface coating. The ventilator fan is of circulating type with isolating plate and is not provided with a spiral casing. It does not transport air as ventilator fan of the VNG type, but only circulate. Therefore there are not any capacity diagrams. The suction mouth is fixed to a steel structure – see the design scheme. The ventilator fan is intended for circulation of air with temperature ranges of up to 250°C. The air shall not contain abrasive particles. The ventilator fans may be manufactured with speed regulator, but only for speed drop (min. 700 r.p.m.). If you want to order the speed regulator, please cite it in the order.

The ventilator fans shall be in operation until the temperature of the transported air has dropped below +80°C.
