INDUSTRIAL FANS
Glass-fiber reinforced plastic blades, in comparison with metal blades, have much higher strength-to-weight ratio and rigidity, they don’t corrode and are fit for maintenance under high humidity conditions and in the wide range of chemical active media.
The ideally smooth polished surface of a glass-fiber reinforced plastic blade ensures high aerodynamic characteristics increasing the efficiency of fan maintenance. Moreover, power consumption, noise, mechanical components wear are decreased.
The right choice of materials and technologies of manufacturing is proved by the long-term experience of reliable operation of the blades of our production at the metallurgical works of Krivoj Rog region.
The manufacturer ensures the monitoring of the blades in the warranty period and carries on post-warranty maintenance.
The blades are made according to TU U 29.2-31043814.001-2003.
