I8690ES SP1 KNORR-BREMSE Twin Cylinder Air Compressor

This high-strength twin cylinder air compressor is engineered to provide reliable pneumatic pressure within the heavy commercial vehicle air brake system. Designed with a robust water-cooled architecture, the component ensures stable performance under demanding operational cycles. The integrated ESS feature and water-cooled valve plate contribute to enhanced thermal management and long-term durability during intensive service.

I8690ES SP1 is the OE-equivalent of the KNORR-BREMSE I8690ES SP1 twin cylinder air compressor used in KNORR-BREMSE systems. This component maintains strict compatibility with heavy commercial vehicle pneumatic infrastructures, ensuring seamless integration into existing assembly lines. The technical specifications include a 75.00 mm cylinder bore and a 440cm³ swept volume to meet precise industrial standards.

For workshop technicians, this unit offers straightforward installation thanks to its standardized M26x1,5 air ports and M16x1,5 water ports. Regular maintenance of the cooling lines and checking the through-drive integrity is recommended to ensure optimal air production. This part is essential for maintaining consistent air pressure in professional heavy-duty braking environments.
