General information

– axial single-stage with explosion-proof detachable motor/engine

Default configuration:

– straightener

– mouth

By request:

– silencer

– engine 380/660V or 660/1140V

Full pressure regulation, developed by the fan in the working area, is realized through the rotation of the impeller blades on stopped fan. Inside the fan case there is a straightener, which provides straightening of air flow and increase total fan pressure. The mouth improves the conditions of air inlet, increases the full pressure, reduces fan noise. The fan is connected to the pipe column by the socket. For ease of transportation and installation the fan is mounted on skids and has loops that allows to hang it to the roof of the mine working.

Function

The mine fans for local ventilation are designed for ventilation of blind workings in mines, including gas and dust hazardous, if the air density to 1,3 kg/m3, at the temperature of from -20 to +35 C, when dust to 50 mg/m3 and at the relative humidity up to 95% (at the temperature +25C).

Aerodynamic characteristics allows to use the fan in a relatively small dead-end workings.
