The range of shaft fans supplied by Balkancorex d.o.o. is quite diverse and includes many design models that differ in technical features and installation method, including shaft fans of local ventilation. This type of equipment got its name from the fact that it is located directly in the places where the work is currently concentrated.

Local shaft fans are classified as explosion-proof units, the blades of the impeller of which are characterized by increased resistance to mechanical damage. They have been certified and are optimally suited for ventilation of dead ends of mines with a high content of foreign matter in air masses with an acceptable density from 1200 mg to 1300 mg/ cubic meter and dust content up to 50 mg/ cubic meter.

Design features of mine fans for local ventilation of VMEVO

They are designed on the basis of the latest scientific and technical achievements in the field of ventilation equipment for the mining industry.

• The impeller of the unit is made of high-strength carbon steel, resistant to mechanical damage, which provides increased reliability and durability of the entire structure.
• The design of the equipment involves connecting several units into one, to ensure an increased air supply to the production site.
• The presence of a node that prevents surging operation and expands the working field of the device.
• The use of brass protectors, which eliminates the possible formation of sparks in friction zones.

When installing the equipment, it should be borne in mind that the fan must be positioned horizontally with respect to the floor surface, with a maximum deviation of 30 °.
