The Liutech LUY050-7 is a portable, oil-injected screw air compressor designed for heavy-duty, off-road, and construction applications. It is powered by a 191kW diesel engine (often utilizing Kubota), offering a free air delivery of 5 cbm/min (180-185 cfm) at 7 bar (100 psi). It features a robust design suitable for mining, road repair, and jackhammer operations.
For the demolition for building and road maintenance, compressed air is essential on the job site to power the tools. Liutech offers compressor in a wide size of range to fit air flow and pressure requirements of the job — all designed to be robust and reliable to meet the needs of tough, demandingconstruction environments.APPLICATIONS: On construction sites, Liutech portable air compressors are typically used to power hand-held pneumatic breakers, jack hammers, air guns, shotcrete equipment, pneumatic wrenches, nut runners and more. They are commonly used in applications such as building sites, road maintenance, bridges, tunnels, concrete pumping and shotcreting.Dimension stone quarries, stabilization projects and foundation excavation demand equipment that can stand up to hot, dusty working conditions. Liutech compressors are designed to do just that. High-performance engines deliver the power margin to work in tough environments. Large fuel tanks allow uninterrupted operation for a full work shift. Plus, an oversized cooler pack helps ensure reliable performance in high ambient temperatures. The compressor controller, plus electrotonic engine, makes the user experience more easier, more convenient and faster. Improving working efficiency.
