Mine fan with electric drive VVM-8
The VVM-8 counter-rotating shaft mine fan with an explosion-proof electric drive is designed to ventilate dead-end mines with a cross section of 16 to 35 m2 at an air density of 1.3 kg / m3, a temperature of 268 to 308 K, dust content of up to 50 mg / m3 and relative humidity up to 95% (at a temperature of 298 K).

Kemerovo Engineering Plant "KemMash"Description
During operation, the fan is installed in a horizontal position with a permissible deviation of the fan axis from the horizontal of not more than ± 30 °. A distinctive feature of this type of fan from VME-2 fans is a significantly higher created head with a smaller nominal diameter and greater efficiency, due to the absence of losses in rectifying devices and loss of twisting at the fan outlet. If necessary, VVM-8 fans can operate with one engine turned on, which increases the efficiency of the machine. At the request of the consumer, the fans can be supplied with voltage 380/660 V and 660/1140 V.
Advantages:
modern aerodynamic design with high pressure characteristic.
thermal protection with the ability to turn off the fan when the normal temperature of the motor winding is exceeded.
fan blades are made of non-combustible materials.
profitability.
at the request of the customer, the fan can be equipped with a silencer.
