Air-Electric Fans

Air-electric fans are intended for separate ventilation, dustremoving and cooling devices in underground coal mines. They may be used both for suction and delivery systems with an air pipe system inclination of up to 90° against the horizontal axis.


In case of the electric drive shutoff and operation with the air propulsion, the electric motor is stalled and thus not generating any voltage on the electric motor terminals, even if the fan wheel is actuated by the air turbine.


For air drive operation, the fan is certified for atmospheric condition IM1; in case of electric drive operation it is IM2. The fans are ATEX-certificated according to the Directive 94/9/EC .


Air-electric fans may switch between the air and electric drives. The air-electric fan is automatically switched over to the compressed air drive mode in the event of power supply failure.
