LP4996 KNORR-BREMSE Twin Cylinder, Air Compressor

The twin cylinder air compressor is a critical component within the pneumatic systems of heavy commercial vehicles, ensuring consistent air pressure for braking and suspension functions. This unit is engineered with high-strength components to maintain operational reliability under demanding industrial conditions. Its robust construction is designed to meet the precise technical requirements of modern heavy-duty vehicle architectures.

LP4996 is the OE-equivalent KNORR-BREMSE twin cylinder, air compressor used in KNORR-BREMSE systems. This component features a cylinder bore of Ø88.00 and a stroke of 50 mm, providing a swept volume of 608cm³. It is specifically designed for water-cooled applications, ensuring optimal thermal management during operation.

For workshop technicians, this part offers seamless integration into existing pneumatic circuits. The assembly includes a through-drive system and an ESS feature to maintain system integrity. Maintenance professionals should verify the M16x1,5 water inlet and outlet ports and the M26x1,5 air outlet port during installation to ensure perfect fitment and prevent leakage in the air brake system.

Proper installation of this twin cylinder compressor is essential for the longevity of the vehicle's air supply. The water-cooled valve plate and specialized port configurations are designed to handle high-pressure cycles without compromising performance. Regular checks of the air unloader port and water cooling lines are recommended to maintain optimal service intervals.
