Glass-fiber reinforced plastic blades have, in comparison with metal blades, higher specific durability and rigidity, they don’t corrode and are suitable for exploitation under high humidity conditions and in a wide range of chemically active media. Ideally smooth polished surface of a plastic blade provides it with high aerodynamic characteristics that increases the efficiency of a ventilator operation. In addition, the power consumption, noise, mechanical part wear of a fan are decreased.
Correctness of techniques of design and applied production technologies are confirmed by the long-term experience of reliable maintenance of the blades of our production at the Nikolaev allumina plant (“Russian Aluminium” joint-stock), Cherkassy joint-stock company “AZOT”and other Ukrainian enterprises.
The blades are produced according to TU U 29.2-31043814.001-2003.
The conditions of the delivery are stated in the price-list.
