LP4986 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide reliable air pressure for heavy commercial vehicle braking systems. Designed with a high-strength component architecture, it ensures consistent performance in demanding environments through its advanced water-cooled structure and robust internal assembly.

LP4986 is the OE-equivalent of the KNORR-BREMSE LP4986 twin cylinder air compressor used in KNORR-BREMSE systems. This component features a Ø88.00 cylinder bore and a 50 mm stroke, providing a total swept volume of 608cm³. It is specifically engineered for high-load cycles within the air brake system.

For workshop technicians, this unit features an M26x1,5 air outlet port and an M22x1,5 air unloader port. The water cooling system utilizes M16x1,5 inlet and outlet ports to maintain optimal operating temperatures. The inclusion of the ESS feature ensures advanced system integration and reliability during long-haul operations.

Maintenance of the air brake system should be performed by qualified technicians to ensure the integrity of the water-cooled valve plate and the through-drive mechanism. Regular checks of the air inlet and outlet ports are recommended to prevent leakage and maintain optimal pneumatic pressure.
