Portable Diesel Screw Air Compressor
Towable air compressor provides the power needed to run a variety of tools and equipment. These compressors are used in construction, street repair, refineries, and demolition.
The main engine and the diesel engine are directly connected through a high elastic coupling with the large diameter rotor design of the third generation 5:6, and there is no increasing gear in the middle. The speed of the main engine is the same as that of the diesel engine and the transmission effects achieved a higher rate, better reliability, longer-life for the new technology pull behind air compressor.
