II30899 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty grade twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's braking and control systems. The unit features a robust design with a Ø88.00 cylinder bore and a 50 mm stroke, ensuring a stable 608cm³ swept volume during operation. Designed specifically for water-cooled applications, it maintains optimal thermal stability under heavy commercial vehicle workloads.

II30899 is the OE-equivalent of the KNORR-BREMSE II30899 twin cylinder air compressor used in heavy commercial vehicle systems. This part is precisely engineered to meet the rigorous standards of the KNORR-BREMSE system architecture. It features a specialized water inlet and outlet configuration with M16x1,5 ports to ensure efficient heat dissipation during high-pressure cycles.

For workshop technicians, this component offers seamless integration into existing pneumatic layouts. The assembly includes an M22x1,5 air unloader port and an M26x1,5 air outlet port to facilitate standard installation procedures. Regular maintenance of the water-cooling lines and checking the valve plate integrity is recommended to ensure long-term reliability in heavy commercial vehicle fleets.

The technical construction focuses on durability and precision, featuring a through-drive design and integrated ESS functionality. This ensures that the air compressor maintains its functional capacity even under extreme thermal stress, making it a reliable choice for professional fleet maintenance.
