LP3977 KNORR-BREMSE Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component designed to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Engineered for high-strength performance, it utilizes a water-cooling mechanism to ensure thermal stability during operation. The robust construction and precision-engineered ports allow for reliable air compression and system longevity in demanding environments.

LP3977 is the OE-equivalent of the KNORR-BREMSE LP3977 single cylinder air compressor used in heavy commercial vehicle braking systems. This technical component features a 360cm³ swept volume with a cylinder bore of Ø92.00 and a 54mm stroke. It is designed to maintain high performance standards within the air brake compressor category, ensuring seamless integration with existing pneumatic hardware.

For workshop technicians, this unit is designed for straightforward installation and maintenance. It features an M26x1,5 air inlet port and an M22x1,5 air outlet port, alongside M16x1,5 water ports for efficient thermal regulation. Ensuring the water-cooled valve plate remains clean and the connections are secure is essential for optimal service intervals and system pressure stability.

Maintaining the integrity of the air supply is vital for heavy vehicle safety. This part is engineered to meet the strict requirements of modern pneumatic systems, providing stable output even under high-load operating conditions typical of long-haul transport.
