1300 290 310 Unloader Kit — KNORR-BREMSE

This unloader kit serves a critical role in the pneumatic regulation of the air brake compressor system, ensuring stable pressure management within the braking circuit. Manufactured with heavy-duty grade materials, the component provides reliable performance to maintain the operational integrity of the air compressor during intensive driving cycles.

1300 290 310 is the OE-equivalent of the KNORR-BREMSE K159064K50 unloader kit used in VOLVO FMX Euro6, FM Euro6, and FH Euro6 heavy commercial vehicles. This precision-engineered part ensures seamless integration with the original compressor systems to maintain optimal pneumatic output.

Workshop technicians should ensure that the compressor housing is thoroughly cleaned before installing this kit to prevent contamination. Regular inspection of the unloader function is recommended during routine service intervals to prevent pressure regulation issues. This kit is designed for efficient assembly within the air brake compressor assembly to support long-term reliability in heavy-duty applications.
