The OEM Connection: 470K in Factory-Fitted Bus AC
The BOCK FKX40/470K (FK40 470K) is an original equipment compressor for bus air conditioning, fitted and cross-referenced by Yutong and other major Chinese coach manufacturers. When the factory-fit unit fails, the aftermarket answer is a like-for-like FKX40/470K replacement – same displacement, same mounting, same refrigerant circuit behaviour.
We supply the FKX40/470K both as an original new unit and as a professionally remanufactured compressor. Fleet managers, AC workshops and parts distributors across Africa, the Middle East, Latin America and Europe rely on this model as a drop-in fix for their coach fleets.
