II31730 KNORR-BREMSE Twin Cylinder Air Compressor

This heavy-duty Twin Cylinder Air Compressor is engineered to provide consistent air pressure within the braking system of heavy commercial vehicles. Designed with a high-strength component structure, it features a Ø88.00 cylinder bore and a 50 mm stroke to achieve a swept volume of 608cm³. The unit is water-cooled to ensure thermal stability during intensive operation, making it an essential component for maintaining pneumatic system integrity.

II31730 is the OE-equivalent of the KNORR-BREMSE II31730 Twin Cylinder Air Compressor used in KNORR-BREMSE systems. This part is manufactured to meet strict technical standards for compatibility and performance. It features a specialized water inlet and outlet configuration (M16x1,5) and an air unloader port (M22x1,5) to facilitate seamless integration into existing vehicle architectures.

For workshop technicians, this component offers precise fitment with an M26x1,5 air outlet port and a Ø29 air inlet port. The inclusion of the ESS feature and a water-cooled valve plate ensures reliable operation under high load. Regular inspection of the water cooling ports and connection points is recommended to maintain optimal service intervals and prevent system downtime.

Professional installation requires attention to the water cooling interface to ensure maximum efficiency. This assembly is designed for heavy commercial vehicle applications where high-strength components are critical for safety and reliability.
