Description

The twin cylinder air compressor is a vital component for maintaining consistent pneumatic pressure within the heavy commercial vehicle braking system. This component is designed to provide reliable air compression through a dual-cylinder mechanism, ensuring the stability of the pneumatic circuit under demanding operational cycles.

II30899ATV is the OE-equivalent of the KNORR-BREMSE Twin Cylinder, Air Compressor used in heavy commercial vehicle systems. This high-strength component features a cylinder bore of Ø88.00 and a 50 mm stroke, delivering a swept volume of 608cm³. It is specifically engineered for compatibility with KNORR-BREMSE hardware and includes a water-cooling system with M16x1,5 ports to manage thermal loads effectively.

Workshop technicians should ensure the water inlet and outlet ports are properly connected to maintain the thermal regulation of the valve plate. The unit includes an ESS feature and is designed with a through-drive capability for seamless integration. Regular inspections of the air outlet (M26x1,5) and unloader port (M22x1,5) are recommended during routine maintenance to ensure optimal pneumatic performance and system longevity.
