The Tukjang Area Coal-Mining Complex has established the compressor production process.

Compressed air is produced by the water ring by the rotation of the spiral fans. The compressor is an energy-saving one.

It is simple in structure and small in volume and mass.

It is very effective in producing compressed air needed in rock-drill and loader. It has been proved that its utilization rate is very high.

It can be used not only in the fields of metallurgy, chemistry, mining, spinning and weaving, paper and agriculture but also in the fields of public health and foodstuff industry.
