Explosion Proof Screw air compressor for Coal Mining with KA MA Certificate

The pneumatic tools and spraying equipment can be used in digging tunnel. It  often confronts the problem of low efficiency of compressed air in the pit. So the pressure decreases for the long pipeline. While this kind of air compressor can operate safely in the development area under the pit and moves forward along with the digging process. It keeps high pressure, raising the efficiency of pneumatic machinery by 30% even one times and decreasing the electricity consumption

 by 30%. In additional, it also saves the pipeline.This kind of air-compressor is also applicable in the funnel construction engineering.
