Description

The heavy-duty single cylinder air compressor is engineered to provide reliable pneumatic pressure for critical braking systems in heavy commercial vehicles. Designed with a robust construction, this component ensures consistent air delivery and high-strength performance under demanding operational conditions.

LK3840 is the OE-equivalent of the KNORR-BREMSE LK3840 single cylinder air compressor used in KNORR-BREMSE systems. This product is a direct replacement designed to meet strict technical specifications for seamless integration and optimal system pressure management.

For workshop technicians, this water-cooled unit features an M26x1,5 air inlet port and M18x1,5 air outlet port for precise assembly. Maintenance of the water cooling circuit and checking the M16x1,5 inlet/outlet connections is essential to ensure long-term durability and prevent overheating during service intervals.

This component is specifically designed for heavy commercial vehicle applications where high-strength parts are required to maintain pneumatic system integrity. Proper installation and adherence to the specified port sizes are vital for maintaining the efficiency of the air brake system.
