Product Details

The LGZJ-30/35-35/25K is a high-pressure air compressor in the LGZJ series, built for demanding industrial duty. Its twin-screw airend runs oil-injected compression, with aftercooler and oil separator conditioning the discharge. The unit pairs with DTH hammers and button bits for drilling, and suits PET bottle blowing, pipeline pressure testing, breathing air systems and industrial cleaning. Kaishan supports it through its service network, spare parts supply and operator training.
