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.
Features1. 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
