VENTILATOR FANS VNS

One-sided suction ventilator fans of the VNS type are of a radial-flow low-pressure design with directly installed electric motors. These ventilator fans are manufactured for a non-explosive environment as well as for a potentially explosive working environment – Zone 2. The supporting frame is round the casing and holds el. motor. The ventilator fans are intended for transportation of air for temperatures ranges of up to 50°C. The air shall not contain solid impurities which could deposit on the fan propeller.

One-sided suction ventilator fans of the VNS type are of a radial-flow low-pressure design with directly installed electric motors. The supporting frame is round the casing and holds el. motor. It stands on four silenblocks. The ventilator fans are intended for transportation of air for temperatures ranges of up to 50°C. The air shall not contain solid impurities which could deposit on the fan propeller. These ventilator fans are manufactured for a non-explosive environment as well as for a potentially explosive working environment – Zone 2. The ventilator fans are powered with flange electric motors where the fan propeller is set overhung on the shaft of the electric motor. The electric motor is fixed on a steel frame with the suction mouth of the fan directed downwards. The electric motor operates in a vertical position. The frame is provided with anti-corrosion surface coating. The casing and the fan propeller are zinc-coated. Ventilator fans are made in left or right-hand construction. There is a left-hand construction on the scheme. Position of the construction shall be cited in the order. The ventilator fans intended for non-explosive environment may be manufactured with speed regulator, but only for speed drop. Use of speed regulator with ventilator fan for Zone 2 is forbidden. If you want to order the speed regulator, please cite it in the order.
