Designed for ventilation of closed and operating mines, mines, tunnels with a productivity range of 20-840 m / s and a static pressure of 100-6700 Pa, and can also be used in general industrial reversible ventilation systems.
They are completed with adjustable inlet guide vanes designed to increase the maximum fan pressure by 15-20% without reducing efficiency and for deep economical regulation. In the “Reverse” mode, the inlet guide vanes significantly increase the reversibility of the fans. The version with an anti-tearing device ensures stable operation of the fan under variable characteristics. They can be completed with devices for noise reduction, air heaters, connecting pipes.
