VENTILATOR FANS VRS

One-sided suction ventilator fans of the VRS type are of a radial-flow medium-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 ventilator fans are intended for transportation of air within temperature ranges between –20°C and +50°C. The air shall not contain solid impurities which could deposit on the fan propeller.

One-sided suction ventilator fans of the VRS type are of a radial-flow medium-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 (labelled as Z2). The ventilator fans are powered with flange or bottom electric motors, where the fan propeller is set overhung on the shaft of the electric motor. The electric motor operates with its shaft in a horizontal position. The casing of the ventilator fan is made of zinced plates. The holder of the electric motor is made of plates and profiles with anti -corrosion surface coating. The fan propeller is zinc-coated and suction mouth is aluminium. The ventilator fans are intended for transportation of air within temperature ranges between –20°C and +50°C. The air shall not contain solid impurities which could deposit on the fan propeller. Please specify the position of ventilator fan in the order according of numbering on the picture. There is an option to use a speed regulator for speed drop of ventilator fans manufactured only for non-explosive environment. If you want to order the speed regulator, please cite it in the order.
