Water wells and geotechnical applications that require very deep drilling depend on high-powered air compressors to drive the drill rig. Liutech compressors are designed to get the job done. They feature an efficient, fast-reacting speed regulator that delivers consistent outlet pressure for stable hammer/drill operation and a high penetration rate. High pressure ensures faster operation, while high low ensures larger drill diameter. And high ambient
temperature operation is standard for reliable performance in demanding conditions, job after job.
APPLICATIONS: The Liutech range is suitable for Down The Hole (DTH) and rotary drilling, offering a comfortable operating zone for drill hole diameters from 4.5 to 15 in (114 to 351 mm). Common applications include drilling for water wells and foundations for high-rise buildings, as well as geotechnical/geothermal applications.
