Core Advantages of Our Diesel Screw Technology
01.
Two-Stage Screw Advantage
Delivers more air per horsepower with lower operating temperatures, leading to better fuel efficiency and longer component life compared to single-stage compressors.
02.
All-Terrain Mobility
The robust towable air compressor design with 4 wheels allows for easy transport between job sites, even over rough ground.
03.
Built for Harsh Environments
The enclosed canopy offers superior dust-proof and water-proof protection, and the high-capacity cooling system ensures operation in high-temperature environments.
04.
Pure Air Output
An advanced oil-gas separation system guarantees low oil carry-over, providing clean air that extends the service life of your valuable pneumatic tools.
Professional Applications
Where the ZD-20/20 Diesel Air Compressor Excels
Widely used in mining, tunneling, bridge construction, and emergency rescue for powering high-pressure pneumatic tools and equipment in off-grid environments.
Underground & Open-Pit Mining Operations
This mining air compressor provides continuous, high-pressure air to power face drilling rigs, pneumatic rock breakers, and ventilation systems. Its rugged build and dust protection are essential for extreme mining conditions.
Remote Bridge and Road Projects
As a mobile high-pressure air source, it easily moves across large sites to operate pile drivers, caisson sinking equipment, and other bridge construction machinery.
Tunnel and Subway Construction
Ideal for tunnel drilling and shotcreting, supplying steady air to jackhammers and spraying equipment. The stable 20-bar output ensures efficient operation of all pneumatic tools for construction.
Emergency and Disaster Relief
IWith self-contained power, it serves as a critical portable air supply for rescue operations, running lifting bags, cutting tools, and dewatering pumps independently of the grid.
