Core Advantages of Our Diesel Screw Technology
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.
All-Terrain Mobility: The robust towable air compressor design with 4 wheels allows for easy transport between job sites, even over rough ground.
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.
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
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.

FAQ
Q: What is the average fuel consumption of the ZD-20/20?
A: Under typical load (around 70%), it consumes approximately XX liters per hour, making it one of the most fuel-efficient models in its class. Exact consumption varies with load and altitude.
Q: How often does it require maintenance in continuous mining operations?
A: We recommend following the preventative maintenance schedule in the manual. Key intervals include engine oil changes every 500 hours and air end inspection every 2000 hours. Our design simplifies routine checks.
Q: Can it operate in high-altitude or very cold environments?
A: Yes. The engine and control system are configured to compensate for altitude. For low-temperature starting, optional cold-start kits (glow plugs, battery heaters) are available.
Q: Is training provided for operators and maintenance staff?
A: Absolutely. We provide comprehensive operation and maintenance training, either at your site or in our factory, covering startup, daily checks, troubleshooting, and safety procedures.
