kz4331x50 KNORR-BREMSE Twin Cylinder, Air Compressor

This high-strength component is engineered to provide reliable air compression within the pneumatic braking system of heavy commercial vehicles. Designed with a robust dual-cylinder architecture, it ensures consistent pressure delivery and long-term operational stability under demanding service conditions.

The VADEN ORIGINAL kz4331x50 is the OE equivalent of the KNORR-BREMSE KZ4331X50 air compressor used in heavy-duty vehicle systems. This twin cylinder model features a 75.00 mm bore and 50 mm stroke, optimized for high-performance air generation. It is specifically designed to be compatible with KNORR-BREMSE hardware and professional braking systems.

For workshop technicians, this unit features a water-cooled design with dedicated inlet and outlet ports (M16x1,5) to manage thermal loads effectively. The inclusion of the ESS feature and a through-drive design ensures seamless integration with existing engine drive setups. Always verify port dimensions and compatibility with existing pneumatic lines during installation.

Maintaining the correct air pressure and monitoring the water cooling system is essential for the longevity of this compressor. Regular inspection of the valve plate and port seals will help prevent pressure drops in the vehicle's braking circuit.
