11 30 21 Cylinder Head compatible with Mercedes-Benz

What does a compressor cylinder head do?

This compressor cylinder head is a critical cast service component that sits on top of an air brake compressor's cylinder block to seal the compression chamber. It serves as the housing for the inlet and discharge valve seats, ensuring that compressed air is routed correctly through the discharge port while managing thermal loads during operation.

Compatible vehicles and engines

This component is specifically designed for heavy commercial vehicle applications, including Mercedes-Benz CITARO (O 530) models like the GN3 and G, Mercedes-Benz CONECTO (O 345) such as the 18M and 12M, Setra Series 400 (MultiClass S 416 NF/415 UL/415 NF), and CAPACITY units. These parts are often used in conjunction with OM 457 HLA, OM 457 LA, and OM 447 HLA engines to maintain optimal pneumatic pressure.

Installation and maintenance

For workshop technicians performing rebuilds, this part allows for the restoration of compressor performance without requiring a complete unit replacement. It is compatible with WABCO systems. When installing, ensure all valve seats are clean and that the sealing surfaces are free of debris to prevent air leaks under high pressure.
