LP3861 KNORR-BREMSE Single Cylinder, Air Compressor

The single cylinder air compressor is a vital component within the pneumatic braking system of heavy commercial vehicles, ensuring a consistent air supply for optimal braking performance. This unit is engineered to handle high-pressure demands while maintaining structural integrity under continuous operation. By utilizing high-strength components and a robust water-cooling design, it provides reliable service in demanding environments.

LP3861 is the OE-equivalent Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This part is designed for precise integration and features a Ø78.00 mm bore with a 52 mm stroke to achieve a 248cm³ swept volume. It is fully compatible with the technical requirements of the KNORR-BREMSE system architecture.

For workshop technicians and fleet managers, this compressor offers a seamless installation process thanks to its standardized M26x1,5 air ports and M18x1,5 water ports. The water-cooled design ensures stable operating temperatures during long-haul transport cycles. Regular maintenance of the air intake and cooling lines is recommended to ensure the longevity of the single-cylinder assembly.

Choosing high-grade replacement parts like this ensures that the pneumatic system remains responsive and efficient. The precision-engineered through-drive mechanism and water-cooled valve plate provide the durability required for heavy commercial vehicle service applications.
