Турбокомпрессор Cummins QSB6.7 HE300VG для строительной техники

Compatible Models: Cummins QSB6.7 series diesel engines

Suitable Equipment: Excavators, loaders, motor graders, industrial pump stations, and various medium-sized construction machinery.

Housing Material: Constructed from high-strength, heat-resistant alloy castings capable of withstanding extreme temperatures and high-pressure shocks at the turbine end, preventing thermal deformation of the housing.

Precision Dynamic Balancing: Factory-tested for high-speed dynamic balance to eliminate operational vibration, significantly extending the service life of the bearing and rotor systems.

Fluid Dynamic Design: Flow channels optimized for the QSB6.7’s exhaust characteristics, achieving a perfect balance between low-speed torque and high-speed power output while significantly reducing power lag.

Sealing Reliability: Features OEM-grade multi-layer metal seals and high-performance air-floating bearings to effectively prevent oil from entering the intake tract, eliminating issues such as blue smoke and excessive oil consumption.

Ease of Installation: Fully compliant with OE installation specifications; flange positions and oil inlet/outlet ports match the original factory layout, ensuring a "plug-and-play" fit.
