This is a diesel-driven air compressor, which is specially designed and produced for construction machinery, so this air compressor can also be called a construction air compressor. Diesel air compressors use diesel fuel as the driving energy source, compared with conventional air compressors driven by electric power, it has the advantage of not being limited to a fixed location or a fixed range, and does not need to be subjected to the limitations of the length of the electric wire. In addition, the compressor has a higher level of protection to cope with different engineering environments, and has a high degree of adaptability to the project.
