The Liutech LUY120-14 is a high-pressure, portable diesel-driven screw air compressor designed for demanding applications like drilling, mining, and sandblasting. It provides a free air delivery (FAD) of roughly 12 m³/min (424-425 cfm) at a nominal working pressure of 14 bar (205 psi).
Engineered by LIUTECH (a core brand of Atlas Copco Group), the LUY120-14 is built to tackle the harshest off-grid mining environments, combining durability, efficiency and mobility. Powered by a robust diesel engine with 75kW output, it features a heavy-duty screw air end—adopting Atlas Copco’s proven rotor technology—to ensure stable air supply even during long-hour continuous operations. Its compact frame (3650×1580×1820mm) and 1280kg weight allow easy towing by a standard construction vehicle, making it flexible for moving between different mining workfaces without extra equipment.

 

 

Operating the LUY120-14 is user-friendly, even for on-site workers with basic training. First, check the 120L fuel tank and top up with diesel; then inspect the lubricating oil level to ensure it stays within the green range as improper oil level may affect performance. Start the engine, wait for 2-3 minutes to warm up, and adjust the pressure between 10-14 bar via the intuitive control panel—no complex programming needed. Routine maintenance is simple too: clean the air filter every 200 working hours, replace the lubricating oil every 5000 hours, and check for air or oil leaks regularly, which helps reduce downtime and extend the unit’s service life significantly.

 

 

The transformation it brings to mining sites is striking. Before the LUY120-14, most medium-sized mines relied on low-pressure compressors or bulky fixed units, which failed to meet the high-pressure demand of deep rock drilling. This led to slow drilling speed, frequent equipment breakdowns, and high fuel consumption—on average, mines wasted 20% more diesel and completed 35% fewer drilling tasks per day. Now, with the LUY120-14’s 14bar high pressure, drilling efficiency has increased by 40%, and fuel consumption has dropped by 15% thanks to its energy-saving engine design. Its portability also cuts setup time from 2 hours to 30 minutes, letting teams focus more on core operations.
