Description

Main fans VTs-31.5М2, VTsD-31.5М2, VTsD-47.5UM, VRTsD-4.5SM are designed for air feed to coal and ore mines. Fans application in other industrial facilities, which provide air supply in these parameters, is possible as well.

Main fans VTsD-47 “NORTH” and VTsD-42.5 are designed for air supply in large-scale hardly-aerating mining enterprises, including the ones located in Arctic climate.

Main advantages:

Static efficiency = 0.86.
Reliable and trouble-free operation.
Spherical roller bearings with splined fixation on the rotor shaft.
Operating wheels and guide vanes blades are made of stainless steel.
Comparatively low rotor frequency.
