LGCY Single-Stage Diesel Screw Type Air Compressor
LUY series portable screw air compressor is designed for outdoor use and harsh working conditions. It delivers consistent, high-volume compressed air for applications such as drilling, construction, and heavy industrial operations. The air compressor’s robust structure enables reliable performance in extreme climates and challenging terrains.
Features-
1. Each model is equipped with engines sourced from well-known manufacturers. All components are enclosed within a corrosion-treated, weatherproof enclosure
-
2. A high-efficiency multi-stage fuel filtration system with a water separator effectively isolates and removes contaminants
-
3. The robust undercarriage with torsional suspension ensures convenient and safe transportation
-
4. The asymmetric rotor design improves efficiency, while low rotor speed and fewer moving parts minimize wear, providing reliable performance and an extended service life
-
5. Allows reliable operation in high-temperature environments, with working temperatures up to 50°C
-
6. The in-house developed controller, combined with the regulating system, automatically adjusts engine speed to meet operational requirements while minimizing fuel consumption
-
7. The intelligent controller features a fast response curve (Power Xpert), enabling rapid engine acceleration to achieve maximum airflow, while regulating the power curve at specific pressures for improved flushing performance and increased drilling efficiency
8. A high-performance two-stage air intake filter prevents dust and particles from entering the engine and compressor, along with a service indicator alert for when replacement is required
