KZ433 KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a vital component designed to provide consistent air pressure within the pneumatic braking system. This part is engineered with high-strength components to ensure long-term reliability in demanding heavy commercial vehicle environments. Its robust design facilitates stable air supply and efficient compression for critical braking-related functions.

KZ433 is the OE-equivalent of the KNORR-BREMSE Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This specific model features a cylinder bore of Ø75.00 and a stroke of 50 mm, delivering a swept volume of 440cm³. It is designed for water-cooled applications to maintain optimal operating temperatures during intense duty cycles.

Workshop technicians should note the precise technical specifications during installation, including the M26x1,5 air ports and M16x1,5 water ports. The unit includes an ESS feature and a water-cooled valve plate to enhance durability. Proper alignment of the through-drive and secure connection of the water inlet and outlet ports are essential for maintaining system integrity and preventing overheating during service intervals.

Maintenance of this air compressor is crucial for the overall safety of the pneumatic system. Regular checks on the water cooling ports and air inlet/outlet connections will ensure that the twin cylinder assembly operates within its intended parameters without degradation.
