LP4985 SP1 KNORR-BREMSE Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Designed with high-strength components, it ensures stable air production even under demanding operating conditions. The dual-cylinder configuration is specifically optimized for durability and long-term service life in professional workshop environments.

LP4985 SP1 is the OE-equivalent of the KNORR-BREMSE LP4985 SP1 twin cylinder air compressor used in KNORR-BREMSE systems. This component is a precise match for the 7600 880 002 and 1677848 (with gear) specifications, ensuring seamless integration with existing hardware and maintaining system integrity.

For workshop technicians, this unit features a water-cooled design with specific inlet and outlet ports (M16x1,5) to manage thermal loads effectively. The assembly includes an ESS feature and a water-cooled valve plate to maintain optimal performance. Maintenance should focus on checking the water cooling connections and ensuring the M26x1,5 air outlet remains unobstructed to prevent system pressure drops.

The technical precision of this part involves a cylinder bore of Ø88.00 and a swept volume of 608cm³, making it an essential part for heavy-duty air brake systems requiring reliable through-drive functionality.
