Mine local ventilation fans, axial, are designed for ventilation of dead-end mine workings at air density up to 1.3kg/m3, at ambient air temperature from -40C to +40C, dustiness up to 50mg/m3 and relative humidity 98% at temperature +25C.
Main advantages: High energy efficiency object; Increased length and height of skids for easy movement of the fan; Lightweight antistatic composite impeller; Modernised impeller blade, preventing end air flow; Increased efficiency due to the modernisation of the impeller and the use of a coke instead of a fairing; Increased air supply; Increased pressure; Long overhaul interval; Vandal-proof design; Increased corrosion resistance of the impeller, coke; Increased efficiency due to the use of a coke instead of a fairing; Increased air flow; Increased pressure; Increased pressure; Increased pressure; Increased corrosion resistance of the impeller, coke; Increased efficiency due to the use of a coke instead of a fairing.
