II30899 SP1 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty grade twin cylinder air compressor is engineered to provide reliable air pressure within the pneumatic braking system of heavy commercial vehicles. Designed with a high-strength component architecture, it ensures consistent performance under demanding operational conditions.

II30899 SP1 is the OE-equivalent of the KNORR-BREMSE II30899 SP1 twin cylinder air compressor used in compatible heavy commercial vehicle systems. This unit features a cylinder bore of Ø88.00 and a 50 mm stroke, providing a swept volume of 608cm³ for optimal air delivery.

For workshop technicians, this assembly includes a water-cooled configuration with specific port dimensions: an air inlet port of Ø29, an air outlet port of M26x1,5, and a water inlet/outlet setup of M16x1,5. The integration of the ESS feature and a water-cooled valve plate ensures thermal stability during long-haul operations. Proper installation and routine checks of the water cooling lines are recommended to maintain peak system efficiency.

The unit is specifically designed to meet the exact technical requirements of the original equipment, ensuring seamless integration into existing air brake systems without compromising safety or pressure stability.
