Description

This high-strength component is designed to provide reliable air compression within the pneumatic braking system of heavy commercial vehicles. The twin cylinder design ensures consistent performance under demanding operating conditions. It features a robust construction with a cylinder bore of Ø88.00 and a stroke of 50 mm to maintain optimal pressure levels.

The II30899 is the OE equivalent of the KNORR-BREMSE II30899 air compressor used in specialized heavy commercial vehicle systems. This component is engineered for precise fitment, featuring a swept volume of 608cm³, an air outlet port of M26x1,5, and a water-cooled design for thermal stability. It is fully compatible with KNORR-BREMSE systems.

Maintenance technicians should ensure that all ports, including the water inlet/outlet (M16x1,5) and air unloader port (M22x1,5), are checked for seal integrity during installation. Regular inspection of the water-cooled valve plate and the through drive mechanism is recommended to prevent system downtime in the workshop. View the technical details.
