Description

This single cylinder air compressor is engineered to provide reliable pneumatic pressure within the heavy commercial vehicle braking system. Designed with high-strength components, it ensures consistent performance under demanding operational conditions. The component is specifically optimized for water-cooled applications to maintain thermal stability during continuous operation.

LK3840 is the OE-equivalent of the KNORR-BREMSE Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This unit features a precise 80.00 mm cylinder bore and a 45 mm stroke to deliver a swept volume of 225cm³. It is fully compatible with the technical requirements of heavy-duty braking architectures requiring high-pressure air delivery.

For workshop technicians performing system maintenance, this compressor features an M26x1,5 air inlet port and an M18x1,5 air outlet port. The water cooling system utilizes M16x1,5 ports for both inlet and outlet to ensure efficient heat dissipation. Proper installation and regular inspection of the water cooling connections are essential to maintain optimal service intervals and prevent overheating in the pneumatic circuit.

Maintaining the integrity of the air supply system is critical for heavy commercial vehicle safety. This component's robust construction supports the high demands of long-haul transport environments.
