I90499ES KNORR-BREMSE Twin Cylinder, Air Compressor

The technical function of this twin cylinder air compressor is to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Built with high-strength components, it ensures reliable air generation through a robust two-cylinder design. This part is essential for maintaining stable air pressure and system integrity during long-haul operations.

I90499ES is the OE-equivalent of the KNORR-BREMSE Twin Cylinder, Air Compressor used in heavy commercial vehicle systems. This unit features a Ø75.00 cylinder bore and a 50 mm stroke with a 440cm³ swept volume. It is specifically designed to meet the precise requirements of KNORR-BREMSE hardware, ensuring seamless integration into the existing pneumatic architecture.

For workshop technicians, this unit features an M26x1,5 air inlet and outlet port, alongside M16x1,5 water inlet and outlet ports for effective cooling. The assembly includes a water-cooled valve plate and an ESS feature to support high-demand service intervals. Maintenance teams should ensure all port connections are secured according to technical specifications to prevent leaks in the air brake circuit.

Maintaining the air compressor is vital for the overall safety of the vehicle's braking system. Regular checks of the water cooling ports and the integrity of the dual-cylinder mechanism help prevent unexpected downtime in heavy commercial vehicle fleets.
