LP4857 KNORR-BREMSE Twin Cylinder Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's braking system. Designed with a high-strength component architecture, it features a cylinder bore of Ø86.00 mm and a 40mm stroke to ensure efficient air production. The unit is specifically optimized for water-cooled applications, utilizing M18x1,5 inlet and outlet ports to maintain stable operating temperatures during intensive service cycles.

LP4857 is the OE-equivalent twin cylinder air compressor used in KNORR-BREMSE systems. This component is engineered to meet strict technical specifications for compatibility with professional heavy commercial vehicle maintenance requirements. It features a swept volume of 460cm³ and includes an ESS feature for enhanced system reliability and performance stability.

For workshop technicians, the installation process is streamlined by the precision-engineered M26x1,5 air inlet and outlet ports, as well as the M12x1,5 air unloader port. Proper maintenance of the water-cooling system is essential to ensure the longevity of the valve plate and internal components. This part is designed for direct integration into existing pneumatic circuits within heavy-duty truck and bus architectures.
