3VG 50-K fans made of composite materials (based on synthetic resin and fiberglass), with vertical axis of impeller rotation, are designed to create induced draw inside the typical fan cooling towers of water recycling systems in oil refining, petrochemical, chemical, metallurgical and other industries, at the ambient temperatures from - 40 °C up to 50 °C.

Environment characteristics: non-explosive, not containing corrosive gases and vapors in concentrations, able to destroy metal and motor insulation.

The impeller blades are made of composite materials (based on synthetic resins and fiberglass), by contact molding, followed by thermocuring with non-joint input and output feather of the blade edge.

Technical specifications:

  • Motor (drive) power, kW
  • Rotational speed, rpm
3VG 50-K impeller 4VG 50-K impeller
VG 50-22K diffuser VG 50-15K diffuser

Upon the customer’s request, we can change the hub dimensions, as well as impeller size, and introduce other changes to the fan design. The blade has got a combined nature: the spar and mount flange are made of structural steel, the blade feather is made of fiberglass with an internal power set. On special request, to work in erosive environment, blades can be covered with special b = 0.8 mm metal polymers, with HB 155 hardness (GOST 4670), while the wear-resistant polyurethane coating is applied on the front edge of the blade.
