LP4934 KNORR-BREMSE Twin Cylinder, Air Compressor

The LP4934 Twin Cylinder, Air Compressor is a critical component designed to ensure reliable air pressure within the braking system. This high-strength component is engineered to withstand demanding operating conditions in heavy commercial vehicle systems. It features a water-cooled design to maintain optimal thermal stability during operation.

The LP4934 is the OE equivalent of the KNORR-BREMSE LP4934 air compressor used in professional heavy-duty vehicles. This part is specifically developed for compatibility with KNORR-BREMSE systems. It features a cylinder bore of Ø88.00 mm and a swept volume of 608cm³, ensuring consistent performance. The technical configuration includes an air unloader port of M22x1,5 and a water inlet/outlet port of M16x1,5 to facilitate efficient thermal management.

For workshop technicians and fleet managers, maintaining the air compressor is vital for system longevity. Proper installation ensures that the water cooling ports are correctly aligned to prevent overheating. Regular inspections of the air outlet port (M26x1,5) and the through-drive mechanism are recommended to maintain optimal pneumatic pressure in the braking circuit.
