Easy ways to get the answers you need.



Diesel mobile screw air compressor is special designed for water well and geothermal well drilling, which is widely used in highway, railway, mining, water conservancy, shipbuilding, urban construction, energy, military and other industries.


1. Main engine: large-diameter rotor design, the main engine and the diesel engine are directly connected through a highly elastic coupling, and there is no speed-increasing gear in the middle between them engine. The main engine rotates at the same speed as the diesel engine, with higher efficiency, better reliability and longer life.

2. Diesel engine: Cummins, Yuchai and other famous domestic and foreign diesel engines are selected, which meet the national II emission requirements. With strong power, low fuel consumption, and nationwide after-sales service system, users can get rapid and comprehensive services.

3. The air volume control system is simple and reliable. According to the size of the air volume, the air intake volume is automatically adjusted from 0 to 100%, and the diesel throttle is automatically adjusted at the same time, which greatly saves diesel oil.

4. The microcomputer intelligently monitors air compressor exhaust pressure, exhaust temperature, diesel engine speed, oil pressure, water temperature, fuel tank level and other operating parameters.

5. Multi-stage air filter, suitable for dusty working environment. Multi-stage fuel filter, suitable for the current status of domestic oil quality. Oversized oil-water cooler, suitable for high temperature and plateau environments.

6. Spacious maintenance and repair door, all parts needed to be maintained are within easy reach. The maintenance of air filters, oil filters, fuel tanks, batteries and oil coolers is easy and convenient, reducing downtime.

7. Easy to move, it can still move flexibly under the harsh terrain conditions. Each compressor is equipped with lifting rings for safe and convenient lifting and transportation.
