LK4973 - KNORR-BREMSE EURO6, Twin Cylinder, Air Compressor

This high-strength air compressor component is engineered to provide reliable pneumatic pressure for heavy commercial vehicle braking systems. As a twin cylinder unit designed for EURO6 standards, it ensures consistent performance and durability under intense operational cycles. The integration of a water-cooled system and high-strength components makes it an ideal choice for professional workshop technicians and fleet managers looking for stability in air brake systems.

The LK4973 is the OE equivalent of the KNORR-BREMSE LK4973 air compressor used in specialized heavy commercial vehicles. This twin cylinder model features a cylinder bore of Ø86.00 mm and a stroke of 56 mm, providing a total swept volume of 650cm³. It is fully compatible with KNORR-BREMSE systems and meets strict technical requirements for modern engine emission standards like EURO6. The VADEN ORIGINAL 1100 440 001 is the direct replacement for the LK4973 reference.

Technical specifications include an air inlet port of Ø34.50 and an air outlet port of M26x1,5. The unit is water-cooled via M18x1,5 inlet and outlet ports to maintain optimal operating temperatures. Maintenance professionals should ensure that the water cooling lines are clear and that all connections are secured to prevent pressure drops or overheating during operation.

For optimal performance and system longevity, always verify that the installation matches the specific requirements of the vehicle's pneumatic circuit. Consult your authorized distributor to ensure this component meets your specific technical needs.
