The main unit and diesel engine are directly connected via a highly flexible coupling, eliminating speed-increasing gears and resulting in high transmission efficiency and a low failure rate. The large-diameter screw rotor design allows for speeds not exceeding 2400 r/min, with overhaul intervals ranging from 40,000 to 80,000 hours.
Equipped with multiple air supply interfaces of different specifications, it can simultaneously drive multiple pneumatic devices. Widely applicable to diverse work scenarios such as road maintenance, pipeline purging, shipbuilding and repair, and trenchless engineering.
