1300 090 010 KNORR-BREMSE Compatible Twin Cylinder Air Compressor

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure within heavy commercial vehicle braking systems. Designed with a dual-cylinder configuration, it ensures reliable air production and maintains high-strength performance under demanding operating conditions. The unit is specifically designed to integrate seamlessly into existing air brake architectures.

1300 090 010 is the OE-equivalent of the KNORR-BREMSE LK4921 SP1 and VOLVO 70330094 SP1 / 8113634 SP1 air compressors used in heavy duty truck and bus applications. This component is engineered to meet strict technical requirements for compatibility with KNORR-BREMSE and VOLVO hardware systems.

The installation process requires precision regarding the water inlet and outlet ports (M16x1,5) to ensure effective thermal management. The unit features an Ø88.00 mm cylinder bore and a specialized air unloader port (M22x1,5). Workshop technicians should verify all port connections and the through-drive alignment to ensure optimal assembly and prevent system leaks or pressure drops.

Maintenance of the cooling system is essential for the longevity of this water-cooled compressor. Regular inspections of the M26x1,5 air outlet and the Ø29 air inlet ports are recommended to prevent debris buildup. This part is a robust solution for maintaining stable air supply in heavy-duty transport fleets.
