LK4951 SP2 KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a vital component designed to maintain consistent air pressure within the braking system. This part ensures reliable pneumatic performance through its precision-engineered dual-cylinder structure and water-cooled functionality. It is built to withstand the rigorous demands of heavy commercial vehicle environments, providing consistent service life and operational stability.

LK4951 SP2 is the OE-equivalent Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This component is specifically engineered to meet the strict technical requirements of the original equipment. It features a high-strength design with a 720cm³ swept volume and specialized port dimensions (M26x1,5 inlet and M22x1,5 outlet) to ensure seamless integration into the vehicle's air management system.

For workshop technicians, this assembly requires careful attention to the water inlet (M18x1,5) and outlet (M18x1,5) connections to maintain proper cooling. The inclusion of an M10x1 air unloader port and an ESS feature ensures optimized pressure regulation. Regular inspections of the water-cooled valve plate and port integrity are recommended during routine heavy commercial vehicle maintenance to prevent system degradation.
