II33164AT KNORR-BREMSE Twin Cylinder, Air Compressor

This high-strength Twin Cylinder, Air Compressor is engineered to provide reliable air pressure within the heavy commercial vehicle pneumatic system. Designed for high-duty cycles, the component ensures consistent airflow and maintains critical pressure levels required for optimal braking performance and system stability.

II33164AT is the OE-equivalent of the KNORR-BREMSE II33164AT Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This component is specifically built to meet the rigorous demands of professional workshop environments and fleet maintenance schedules.

The assembly features a cylinder bore of Ø88.00 mm and a stroke of 50 mm, providing a swept volume of 608cm³. The unit is water-cooled (W) with inlet and outlet ports measuring M16x1,5 to ensure efficient thermal management during operation. It includes an ESS feature and an air unloader port of M22x1,5 for precise pressure regulation.

Workshop technicians should ensure that all port connections—including the Ø29 air inlet and M26x1,5 outlet—are secured to prevent leaks. Regular inspections of the water cooling lines and the M22x1,5 unloader port are recommended to maintain the integrity of the air compressor system and prevent overheating in high-load scenarios.
