APPLICATION OFVTsG-7M FAN
VTsG-7M fan is designed for reducing volume of gas in mining sections and eliminating methane accumulations at the junctions of rooms and air gates in coal mines dangerous due to gas and dust, by sucking methane-air mixtures from the mined-out space and removing them through rigid pipelines.

The fan is installed in a special chamber or working and is connected to a suction or discharge pipeline.

VTsG-7M design and features

Fans consist of a split housing, a rotor installed in two bearings, a frame, a guide vane, a motor, a noise muffler, an inlet and outlet pipes.

Pressure and flow rate are adjusted by the guide vane.

modern aerodynamic design with a high-pressure characteristic


thermal and vibration protection with the function of switching off the fan when heating and exceeding the bearings vibration normal value


explosion-proof electric motor


brass seals in places of possible frictional sparking


impeller blades are filled with foam, preventing protecting from the water ingress


dynamic balancing of the impeller according to a high accuracy class of


highly reliable design of the guide vane, allowing smoothly changing the power and direction of the air jet


thick lubrication of bearing units


especially rigid massive metal structures of the frame and housing


original petal coupling between motor and rotor


noise muffler with extended service life
