LP3997 KNORR-BREMSE Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable air pressure for heavy commercial vehicle braking systems. Designed with a robust structure, it ensures consistent performance under demanding industrial conditions. The component features a water-cooled system to manage thermal loads effectively during continuous operation.

LP3997 is the OE-equivalent of the KNORR-BREMSE single cylinder air compressor used in KNORR-BREMSE systems. This technical component is manufactured to meet exact specifications for heavy-duty performance. It is fully compatible with the specified technical requirements of the original braking assembly to ensure seamless integration and long-term reliability.

The assembly features a Ø92.00 mm cylinder bore and a 54 mm stroke, providing a swept volume of 360cm³. The unit is designed for water cooling, utilizing M16x1,5 ports for both water inlet and outlet to maintain optimal operating temperatures. Workshop technicians should verify all port connections and cooling line integrity during installation to ensure the high-strength components function within intended parameters.

Maintaining proper service intervals for the air compressor system is essential for fleet stability. Regular inspection of the water cooling ports and the M26x1,5 air inlet/outlet connections helps prevent pressure drops in the pneumatic circuit. This part is designed for professional workshop service and heavy commercial vehicle maintenance.
