Description

The high-strength single cylinder air compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. Designed to provide consistent air pressure, this part ensures the reliability of the vehicle's air brake operations. Its robust construction and water-cooled architecture are engineered to withstand rigorous duty cycles in demanding environments.

LP3986 is the OE equivalent of the KNORR-BREMSE Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This component features a cylinder bore of Ø92.00 and a stroke of 54 mm, providing a swept volume of 360cm³. It is specifically designed for high-performance compatibility within professional heavy-duty vehicle service and maintenance workflows.

For workshop technicians, this unit includes an M26x1,5 air inlet and outlet port, alongside M16x1,5 water ports for efficient thermal management. The through-drive design and water-cooled valve plate ensure optimal durability during long-haul operations. Regular checks of the water inlet and outlet connections are recommended to maintain peak performance and prevent system overheating.
