LP3861 KNORR-BREMSE Single Cylinder, Air Compressor

The technical functionality of this single cylinder air compressor is centered on providing reliable pneumatic pressure within the heavy commercial vehicle braking system. Designed with a water-cooled architecture, it ensures stable thermal management during intensive operation. This component is engineered using high-strength components to maintain consistent performance under high-pressure cycles.

LP3861 is the OE-equivalent of the KNORR-BREMSE Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This part features a cylinder bore of Ø78.00 mm and a stroke of 52 mm, ensuring precise volumetric displacement of 248cm³. It is specifically designed for compatibility with heavy commercial vehicle braking architectures where water cooling is required for optimal durability.

For workshop technicians, installation requires attention to the water inlet and outlet ports, which utilize M18x1,5 specifications. The air inlet and outlet ports are both M26x1,5 to ensure a secure fit within the existing pneumatic lines. Regular maintenance of the cooling system and checking the through-drive integrity are recommended to ensure long-term operational stability in heavy-duty environments.
