Local mine ventilation fans of VMEVO series with built-in explosion-proof motor are designed for ventilation of dead-end coal and ore mine workings
VMEVO FAN
VMEVV FAN APPLICATION
Local mine ventilation fans of VMEVO series with built-in explosion-proof motor are designed for ventilation of dead-end coal and ore mine workings, including mine workings with gas and dust hazard by feeding air through a flexible or rigid pipeline with diameter of 0.6 and 1 m. They are also used in tunnel and gallery driving.
Fans of VMEVO series are certified by Federal Technical Regulation and Metrology Agency of Russia and have a permit of Federal Service for Ecological, Technological and Nuclear Supervision of the Russian Federation for use in coal mines, including mines with gas and dust hazard.

VMEVO fan design
The fan is built on the basis of a new high-pressure aerodynamic scheme, specially designed for optimal operation with ventilation ducts.
The lightweight fan impeller, which increases the reliability and durability of the motor bearings, is made of high-strength carbon steel with increased resistance to mechanical stress

—
If it is necessary to increase the air supply to the mine face and in case of extra-long workings, the fan design provides for the possibility of sequential sectioning of two or more units into a single unit
—
Special antistall device prevents the occurrence of surging modes and expands the working area of the fan
—
Brass protectors are installed in places of possible friction to prevent spark formation
—
At the customer's request, the fans are equipped with noise reduction devices.
